FIELD OF THE INVENTION:
The present invention relates to an integrated, closed-loop, highly efficient renewable energy system designed for rural, semi-rural and urban application. More specifically, the invention provides for a control system that is able to optimize the use of energy drawn from different types of renewable energy sources.
BACKGROUND OF THE INVENTION:
Due to the negative impact of the non-renewable sources of energy on the environment such as climate change and global warming as well as the limitation of the availability of non-renewable resources such as fossil fuels, governments are pushing for the research and commercialization of alternative and renewable sources of energy.
Currently, the main sources of renewable energy include solar energy, energy derived from harnessing hydropower, wind and geothermal activity, or from gasification of biomass or through pyrolysis of non-biodegradable matter. The advantages associated with these renewable energy sources is that they are clean sources of energy and do not produce any net pollution or green-house gas effect unlike nonrenewable sources of energy.
Although these renewable sources of energy have tremendous potential to replace the non-renewable sources, their wide spread use is hindered by a variety of problems. For example, the source is required in copious amounts in the production of electricity, which may be a problem. As another example, solar energy is not available in the night or during the monsoon and unseasonal rains. Similarly, biomass is limited by the

seasonal variation while wind energy is limited by the variability of the wind.
Another major source of energy loss typically found in thermal energy systems is that the energy usage is not often optimized to use all of the energy generated.
These types of inefficiencies in capturing energies result in the higher cost of producing energy, which is the major reason for non-exploitation of viable sources of renewable forms of energy in many countries. Therefore, most developing as well as developed countries continuously rely on non-renewable resources such as coal, petroleum, etc.
Hence there is an urgent need for a highly efficient renewable energy system which can efficiently provide energy to a community in a fully sustainable and cost effective way.
OBJECT OF THE INVENTION:
The main object of the invention is to provide an integrated, closed-loop, highly efficient renewable energy system that optimizes the generation of energy from the various different types of renewable energy production units as per the available renewable energy resources.
Another object of the invention is to provide an integrated, closed-loop, highly efficient renewable energy system having a self-adaptive control system which identifies and finds the optimum operating conditions at which the system ought to operate in order to optimize the energy generated by the electricity producing unit and the energy demands of the various applications based on the energy generation and usage data

collected over a period from the renewable energy processing units and the various applications including thermal units.
Yet another object of the invention is to provide an integrated, closed-loop, highly efficient renewable energy system wherein the unused heat in the electricity producing unit is used by Thermal Application Units for applications requiring heat energy such as laundry, washing and cooking.
Yet another object of the invention is to a provide integrated, closed-loop, highly efficient renewable energy system wherein the control system is capable of monitoring of the energy resources produced by the renewable energy production units and apportioning the said energy resources between the electricity producing unit and Thermal Application Units in such a manner that the system operates with peak achievable efficiency.

DETAILED DESCRIPTION OF INVENTION:
The present invention relates to the integrated, closed-loop, highly
efficient renewable energy system designed for rural, semi-rural and
urban application. The present invention provides the integrated energy
solution for most of the basics needs of a community, village, an
organization in a semi-urban area, hospital, and others in a sustainable
way. It provides the basic needs of cooking, water, cleaning, and
electricity along with optional additional industrial processes such as desalination. It uses solar power and other locally available renewable energy resources, while cleaning up waste. It can also sustainably provide jobs and income.
“Heat " is hereby defined to be any medium that contains heat in either present actual or latent form, and could include any form of, including but not limited to, heat generated through steam, hot water and fuels such as hydrogen, producer gas and biogas. The Renewable Energy Processing

Unit may also contain any form of storage of the said heat or storing a product of converting the heat to another medium.
Fig. 1 describes the architecture of the integrated, closed-loop, highly efficient renewable energy system which is designed for rural, semirural and urban application.
The system comprises of Renewable Energy Processing Unit (1100),
System Control Unit (1200), Thermal Application Unit (1400). The
Electricity Producing Unit (1300) is also illustrated in the Figure 1. However the system can be implemented with or without the Electricity Producing Unit (1300).
The Renewable Energy Processing Unit system (1100) comprises of the heat generating subunits including, but not limited to Solar Unit (1110), Biomass Unit (1130), and Pyrolysis Unit (1140). These subunits are employed as single or multiple units, either single or in combination based on the specific resources of the community. The Solar Unit also has an optional storage unit (1120). The Electricity Producing Unit (1300) has one or more energy conversion devices, for example a gas turbine or a steam turbine or an Organic Rankin turbine.
The System Control Unit (1200) comprises of Data Collection Subsystem (1220), Data Storage Subsystem (1250), Control Actuator Subsystem (1230), Control Subsystem (1210). The Control Subsystem (1210) links the Data Collection Subsystem (1220) to the Data Storage Subsystem (1250). The Thermal Application Unit includes one or more subunits selected from Cooking, Air conditioning, Steam washing steam, desalination, or others, either single or in combination.

The Renewable Energy Processing Unit (1100) in its heat generating subunits i.e. Solar Unit (1110), Biomass Unit (1130) and Pyrolysis Unit (1140) creates heat by using local community resources such as biogas, solar energy, which serves as thermal input in one or more forms (hot water, steam, hot air, fuels) to the Electric Producing Unit (1300) as well as the Thermal Application Unit (1400). The heat generating subunits of the Renewable Energy Processing Unit (1100) work either as single unit or as a group which supplement each other.
The heat in the form of steam (10) is fed to the energy conversion device of the Electricity Producing Unit (1300) to produce the electricity and during this process some unused heat is also produced which is passed on to the Thermal Application Unit (1400) as a rejected heat (16).
The Thermal Application Unit (1400) fulfils the various needs of the community for example cooking, Air conditioning, hot water for bathing, washing and drying, and steam cleaning.
The Control Subsystem (1210) comprising of processors, either server based, personal computer, embedded systems, distributed, or others, As illustrated in Figure 1, the Control Subsystem (1210) of the System Control Unit (1200) continuously monitors (12) the heat generating subunits (1110,1120,1130,1140…n) of the Renewable Energy processing Unit (1100), and also continuously monitors the flow of heat (13) to the Electricity Producing Unit (1300) and the Thermal Application Unit (1400). During monitoring of Renewable Energy Processing Unit (1100) the Control Subsystem (1210) fetches the information data with regards to the

availability of resources via the data collection Subsystem (1220) and transfers it to the Data Storage Subsystem (1250).
Further, the System Control Unit (1200) also monitors the load demand (17) at the various subunit of the Electricity Producing unit (1300) and Thermal Application Unit (1400) in which data regarding the demand of the end user at the subunits of the Thermal Application Unit is collected at the Data Storage Subsystem (1250) via Data Collection SubSystem (1220).
Based on the data/information collected in the Data Storage Subsystem (1220) and comparison with the present inputs of demand of heat, consumption of heat and production of heat, the Control Subsystem (1210) via Control Unit Actuator Subunit (1230) continuously sends the controls signals to the Renewable Processing unit to control the amount of production of heat (11) in the heat generated unit (1110,1120,1130,1140..n). of the Renewable Energy Processing Unit (1100). For example if there is less availability of solar energy in solar unit (1110) while availability of biomass increases in the biomass unit then control unit sends control signal to Renewable Processing Energy unit (1100) to produce maximum thermal energy from the Biomass unit (1130) as compare to Solar Unit (1140).
As depicted in Figure 1 on basis of data collected in the Data Storage Subsystem, the Control Subsystem (1210) controls the amount of heat i.e. heat flow (14) to the Electricity Producing Unit (1300) and Thermal Application Unit (1400) via sending control signal through Control Actuator Sub-system (1230).

For example in subunits of Thermal Application Unit(1400) if user switches off cooking equipment in the Thermal Application Unit then System Control Unit automatically readjust the loads for the other process or subunits.
According to one embodiment, the Control Subsystem (1210) sends the Bypass control in which the thermal heat inputs (10) generated at the Renewable Energy processing Unit (1100) is transferred to the Thermal Application unit directly as bypassed heat (15).
The system is scalable and can be operated by a local technician with minimum training. The System Control Unit (1200) also have a graphical interface (1240) which is user interface where the technician or user can set the input for the individual inputs and the system further automatically adjust the other inputs in order to maintain the energy generation capacity to meet the energy required for output.
The various subunits of the Renewable Energy Processing Unit (1100) are specifically designed as per available resources that are ambient where they are installed. For example in rural and semi suburban areas the solar unit can employ a Solar Power Tower layout as land space is extremely limited in many rural and semi-urban areas. A power tower requires less area due to its use of 3D concentration (dual axis tracking), which gives it a much higher concentration ratio, which leads to higher temperatures and higher efficiency. An optimal layout is possible in a highly spatially constrained scenario with higher spatial efficiency. The concentrated solar energy powers the tower receiver boiler.

The Biomass Unit (1130) serves as heat input for the system when the solar power is unavailable or limited or planned with smaller capacity than the total energy requirement, there by supplementing solar power for efficient operation. This subunit utilizes various locally available wooden wastes, such as coconut shells, carpentry waste, or other compatible bio-matter (typically available in surplus). Added benefits of the biomass unit are reuse of carbon waste for other purposes, elimination of waste disposal requirements, providing economic support for biomass collectors, and the carbon neutrality.
The Pyrolysis Unit (1240) employs the pyrolysis process to create pyrolysis oil by combusting hydrocarbon based materials, such as plastics and rubber waste, including tires, at high temperatures in an anaerobic environment. The pyrolysis oil has a quality better than fuel/furnace oil, but it is a grade below diesel oil. It supplements biomass gas to the boiler. Incorporating pyrolysis, serves the triple function of a plastic waste free environment, providing fuel for the system and generating revenue even for non-recyclable plastic and rubber waste collectors. Thus, the waste becomes a sellable commodity.
Each subunits of the Renewable energy processing units connects to the boilers which generates heat. For example, the solar unit could have a solar power tower receiver and be powered by renewable energy/fuel resources, such as biogas, generated in the various sub units.
The System Control unit is the core of the entire system because of which the system efficiently provides energy to a community in a fully sustainable and cost effective way.

The System Control Unit (1200) has Control Subsystem (1210) which comprises of a network of wired or wireless sensors and networks and multiple safety systems that handle real-time performance analysis and conduct remote monitoring of energy generation and energy consumption. This can be a wired or wireless system or network, or a combination of the two, and utilizing wireless, wired, or networked sensors and Control subsystems.
Further, the Control Subsystem link the Data Collection SubSystem (1220) to the Storage Subsystem (DCSS) (1250) which has the data storage system for storing data collected periodically.
The Control Subsystem (1210) is a self-adaptive system as it finds and identifies the optimum operating conditions at which the system operates given the demand at the loads and also by analyzing data collected in the Data Storage SubSystem (1250) over a period of time.
The Control Subsystem (1210) is a server which can be selected from dedicated server, a cloud computing server, an embedded system, or a distributed system of any combination of these types. The Control Subsystem (1210) is programmed through learning algorithms in a manner that it continuously looks for ways to improve its performance.
The System Controller Unit (1200) in its storage unit has the database of all system variables, values, inputs, outputs, etc. for future analysis, study, and for self-adaptive algorithms, remote data acquisition, and monitoring, via internet or other means.

In one of the embodiment the system provides the full and flexible utilization of the said heat in the form of steam or hot water produced from using any heat which is not used by the Electricity Producing Unit in the Thermal Application Unit. As aforementioned, the subunits of the Renewable Energy Processing Unit (1100) uses community local resources to generate heat in the form of high quality steam which is fed to the Electricity Producing Unit (1300). The Electricity Producing Unit (1300) employs an electrical turbo generator to generate the electricity which could be either a steam or Organic Rankine Turbine (ORC) turbine-generator. Other turbine/generator types are also possible. The System Control Unit (1200) automatically senses when less solar power is available and automatically assigns more biomass or pyrolysis fuel to be supplied to maintain the required steam flow. The system is designed to generate a predetermined amount of steam or electricity. For example, at about 400 and 40 barns system produces about 1000 - 1200kWh of electricity per day depending on hours of operation of the system. .
The remaining rejected heat (17) by turbine which is energy conversion device is a typical quality of heat for example 6 bar and 200 degree Celsius. The rejected heat is transferred to the Thermal Applications Unit for common community needs.
In the Thermal Application Unit (1400) this rejected heat is used for the thermal processes such as cooking, desalination, air conditioning, laundry (drying and washing), bathing hot water, and steam cleaning, or any other processes requiring steam. Heat exchangers can be used to change the pressure and temperature of the steam.. Flexible and full utilization of heat is used amongst all these processes. The overall system efficiency is expected to be 65 – 75%. The higher system efficiency is obtained by using

all unused heat from the steam exiting the Energy Producing Unit by means of efficiently putting it use for various processes
The flexible and full utilization of heat in the Thermal Application Unit is explained by the non-limiting example.
Example 1: Cooking
For this purpose, rejected heat from the Energy Producing Unit, in the form of steam, is used to generate culinary steam at about 120°C and 2 bars by using a reboiler which could be fueled by Syngas from the Biomass unit or Fuel Oil from the Pyrolysis Unit. This culinary steam is used to cook rice, vegetables, lentils, or other foods either by directly injecting steam or by passing it through a jacketed vessel. A large number of meals (in the hundreds or thousands) can be cooked.
Example 2: Air conditioning
An absorption chiller is a thermally driven cooling system that operates on the principle of cooling by using thermal energy rather than electrical energy. The chiller uses a hot water loop which is heated by exhaust/ unused heat in the form of steam from the Electric Producing Unit, which powers a thermodynamic, hygroscopic process to cool water to as low as 7°C. Cold water is used to condition and cool the air for the AC system.
Example 3: Hot water for washing, drying, steam cleaning, and bathing
Other potential outputs of the system are steam washing, drying, and ironing. Steam cleaning can also be optionally done. The steam is passed through the dryer first. The same steam is then used for washing as well. Steam heated drying has many benefits such as deeply penetrating and moistening clothes and reducing wrinkles though its softening effect. The

high temperature steam more effectively sanitizes clothes and eliminates smells, which is important in hospital environments. It works by heating moisture to the evaporation point. The dryer then circulates this moisture out of the system. Steam cleaning removes tough stains, for example, in laundry used in kitchens. In addition to the above examples, hot bathing water at 45-50 °C can also be obtained from the system.
Example 4: Desalination and other processes
The system can use steam powered desalination to make drinking water. The amount of water is variable and depends on the heat available. Desalination using low-grade thermal energy is ideal for a Combined Cooling, Heat, and Power (CCHP) system in which every bit of heat rejected by turbine is used in order to maintain high combine efficiency. An efficient multistage desalination system consumes a smaller quantity of low-grade heat plus relatively smaller amounts of electricity for pumping sea water than what is required to boil to produce the same quantity of distilled water. After desalination, a UV treatment process is used for drinking, storage and distribution.
Where desalination is not needed, all the remaining heat, whose quantity can be controlled, can be used to power the main process in applications such as in small scale sugar processing or other steam applications. If no other processes are required to be run, the remaining heat can all be used to power a smaller scale Organic Rankine Cycle turbine to generate electricity. Though such a use of the remaining heat to produce electricity will bring down the overall system efficiency, it will be maintained at the maximum possible value, on the average, achievable by any practical system with variable needs.

ADVANTAGES Waste products
The system does not produce any waste product and runs with zero toxic emissions. On the contrary, the biomass and pyrolysis units produce residue carbon black that can be recycled. For example if the rubber is input in the Pyrolysis unit, then it produces 30 to 35 % carbon black which is recyclable, 10 to 15% steel wire, usable gas about 10%, with no pollution or toxic emission. In another case where input is plastic, the pyrolytic unit emits only 10-15% carbon black with no pollution or toxic emission.
Another advantage of the present invention is that the system is scalable and can be operated by a local technician with minimal training. The control system ensures that the system works at the highest efficiency, whenever desalination or some other processing unit is installed, while meeting most of the basic demands of the community energy requirement.
In summary, this is a comprehensive integrated energy solution for meeting most of the basics needs of a community, village, organization in a semi-urban area, hospital, and others, in a sustainable way. It provides the basic needs of cooking, water, cleaning, and electricity along with optional additional industrial processes such as desalination. It uses solar power and other locally available renewable energy resources, while cleaning up waste products. It can also sustainably provide jobs and income. It is decentralized, distributed and uses local resources.
