Specification

DESC:DESCRIPTION:
Field of the invention:
[0001] The present disclosure generally relates to the technical field of distributed renewable resource utilization, and in specific relates to, a microgrid energy management system that optimizes energy production and consumption, thereby reducing energy costs and environmental impact.
Background of the invention:
[0002] A power grid is a vast network of power plants, transmission lines, and distribution centers. The grid constantly balances the supply and demand for energy that powers everything from industry to household appliances. Traditional power grids face challenges such as limited reach, vulnerability to outages, and reliance on fossil fuels. The increasing adoption of distributed energy resources (DERs) such as solar panels and battery storage has paved the way for microgrids.

[0003] The microgrids are localized power systems that can operate independently or in conjunction with the main grid, which offers benefits that include increased resilience, improved sustainability, and reduced reliance on fossil fuels. However, managing the complexity between various DERs and loads within a microgrid requires sophisticated control systems. Microgrids integrate diverse components include generators, storage, and loads, each with unique characteristics and dynamic interactions. This complexity makes it difficult to predict and optimize energy flows, leading to potential issues such as power imbalances and inefficient resource utilization.

[0004] Furthermore, microgrids often prioritize internal energy consumption, minimizing power exchange with the utility grid, which can limit the potential benefits of sharing excess renewable energy and participating in grid balancing services. In addition, conventional protection methods might not be adequate for systems with distributed storage, making data analysis and optimal energy procurement challenging.

[0005] The Internet of Things (IoT) architecture is used to manage and operate microgrids effectively. By leveraging power grid equipment and IoT-enabled technologies, microgrids enable local networks to offer additional services on top of the essential delivery of electricity to local networks that function concurrently with or independently of the regional grid. For data collection, processing, and visualization, as well as with the next wireless generation, many platforms that make use of IoT technologies are used. An electronic communication network, an electronic billing system, and smart meters make up the modern smart microgrid. The smart microgrid will feature automatic distribution, secure distributed energy resources management (DER), and production capabilities.

[0006] In an existing technology, a method for controlling the operation of a microgrid comprises plurality of distributed energy resources that include controllable distributed electric generators and electrical energy storage devices. The method includes periodically updating a distributed energy resource schedule for the microgrid that includes on or off status of the controllable distributed electric generators and charging or discharging status and rate of the electrical energy storage devices and which satisfies a first control objective for a defined time window, based at least in part on a renewable energy generation and load forecast for the microgrid.

[0007] The method further includes periodically determining power set points for the controllable distributed energy resources that satisfy a second control objective for a present time interval within the defined time window, the second control objective being a function of at least the distributed energy resource schedule for the microgrid. However, the method for controlling the operation of the microgrid is less effective for energy utilization. Moreover, the method for controlling the operation of the microgrid has the least probability of sharing the power from microgrids with the utility grid.

[0008] Therefore, there is a need for a microgrid energy management system that integrates microgrids with a utility grid to optimize energy production and consumption. There is also a need for a microgrid energy management system that is energy efficient, safe and reliable. There is also a need for a microgrid energy management system that reduces energy costs and environmental impacts.

[0009] There is also a need for a microgrid energy management system that recovers from outages quickly and improves uptime by avoiding unplanned outages. There is also a need for a microgrid energy management system that is easy to control. There is also a need for a microgrid energy management system that shares the power from one microgrid with another microgrid and avoids creating a burden on the utility grid.
Objectives of the invention:
[0010] The primary objective of the invention is to provide a microgrid energy management system that integrates microgrids with a utility grid to optimize energy production and consumption, thereby reducing energy costs and environmental impact.

[0011] Another objective of the invention is to provide a microgrid energy management system that is reliable, safe and energy efficient.

[0012] The other objective of the invention is to provide a microgrid energy management system that recovers from outages quickly and improves uptime by avoiding unplanned outages.

[0013] The other objective of the invention is to provide a microgrid energy management system that optimizes maintenance and develops more time for electrical assets.

[0014] The other objective of the invention is to provide a microgrid energy management system that utilizes a dual arrangement of solar installations accompanied by battery-equipped microgrid clusters.

[0015] The other objective of the invention is to provide a microgrid energy management system that is easy to control.

[0016] The other objective of the invention is to provide a microgrid energy management system that shares power from one microgrid to another microgrid and avoids creating much burden on the utility grid.

[0017] Yet another objective of the invention is to provide a microgrid energy management system that analyzes gathered electrical parameter data and maintains optimum energy procurement.

[0018] Further objective of the invention is to provide a microgrid energy management system that develops low-cost IoT-based energy management for microgrid clusters.
