Description:FIELD OF INVENTION
A large portion of the world's electricity is still produced from fossil fuels due to the low cost of generating electricity. Such efforts have helped to increase the penetration of these renewable resources into the energy sector which requires an urgent understanding of their impact on the stability of the power system, especially at a high level of penetration. Wind power is the conversion of wind energy into electricity or mechanical energy using wind turbines. Air power is released by allowing it to blow through moving blades using torque on the rotor. The amount of energy transferred depends on the size of the ridge and the wind speed.
BACKGROUND OF INVENTION
Concerns about the environment, the depletion of fossil fuels and the increase in energy demand have fueled the demand for alternative energy sources. Recent advances in renewable energy technologies, coupled with lowering the cost of generating energy units, have opened up opportunities for renewable energy resources to be integrated into power networks. More importantly, unlike conventional energy sources focused on limited areas around the world, renewable energy sources are virtually ubiquitous. Wind power is the most promising of renewable resources from a technical and economic point of view. People have used wind energy since ancient times through their use such as pumping water, grinding grain, cutting wood from saws, etc. Since the 20th century, wind power has found a new application in generating electricity from small wind farms suitable for farms. And residential areas on large scale wind farms that are connected to power grids.

SUMMARY
School system stability of the energy system is the property of the energy system that enables it to maintain a stable operating environment under normal conditions and also to achieve acceptable balance. Name the following network disruption. Such interference in the power network may be small in the form of slow shift load, control operation, etc., and large in the form of loss of a large generator or load, as well as a short circuit in the power cord, etc. The stability of the power system can be classified as the rotation angle of the rotor and the stability of the voltage.
DETAILED DESCRIPTION OF INVENTION
At any given time, the average amount of energy delivered to the power grid from wind production to the total amount of energy delivered to the grid from all sources during that time. For example, if within a specified time, 1000 megawatt-hours (MWh) of electricity is delivered to the grid where 200 MWh is obtained from the wind power generator, the input of wind power at that time is 20%. The stability of the power system can be classified as the rotation angle of the rotor and the stability of the voltage. The rotation angle of the rotor refers to the synchronism in the synchronous machines in the power system, whereas, the voltage stabilization refers to the power of the power system to maintain acceptable voltage across all its buses. Rotor angle stability can be as subdivisions as low signal stability and short-term stability. Small signal stability is the ability of the power system to maintain synchronization following the emergence of small disturbances. In contrast, transient stability refers to its ability to maintain synchronism following major temporal disruptions [9]. Energy system stability is a major concern for the safe and reliable operation of the energy system. The growth of connections, the addition of new renewable technologies and their performance in stressful situations have raised concerns about the instability of the energy system much higher than before.
STABILITY IMPACT OF WIND POWER PENETRATION
Wind power is one of the leading renewable resources being utilized for electricity generation all over the world due to its technological and economic superiority over the rest of the renewable resources. Apart from that, the wind integration has already given beneficial impacts by cutting off carbon emissions from electricity production and reducing the operational costs of the power system. Additionally, the wind power integrated into power networks also adds the capacity value to the power system. In the technical sense, there is no limitation to wind integration; however, such integrations should not reduce the reliability, and must guarantee the stability of the power system. Even though a power system is designed to withstand a wide range of disturbances, small and large, the dynamic behavior of such a power system is determined by the behavior and the interaction of the generators existing there, including the wind generators. Till date, the majority of the wind farms are based on the constant speed technology due to the simplicity in its design, low cost, and robustness.
WIND ENERGY CONVERSION SYSTEM
The normal power system is controlled by power output; however, the wind-based energy system depends on the availability of flexible air from nature. However, with technological advancement and economic competition, wind power is an important source of energy today. These positive qualities exist in addition to other renewable sources, making wind power a clear choice for state-scale power generation. The wind energy conversion system converts wind kinetic energy into electrical energy or other forms of energy. Having the natural friendliness and benefits mentioned above in addition to other resources, wind power has shown tremendous growth over the past decade. Technological advances have improved the reliability and power of wind turbines in addition to reducing the cost of power generation unit. The basic wind power conversion system consists of a wind turbine, an electric generator, power cords and loads as shown in the figure. Horizontal wind turbines and straight wind turbines. Horizontal wind turbine is the most common style of wind turbine in which the turbine rotates on a horizontal axis, and on a straight wind turbine is the main. Rotor shaft vertically. Grid wind farms are mainly type of horizontal wind turbines. These turbines can also be classified as types of fixed speed. In wind turbines of fixed speed, the rotor is connected to the generator, and the stator winding is connected directly to the grid. For flexible wind turbines, a DFIG-based generator, a permanent synchronous magnet generator and a rotary synchronous generator are used. Among them, a flexible wind technology that uses a DFIG-based generator is the most popular wind technology today. In this thesis, DFIG-based generator-powered flexible wind engine technology is considered to analyze stability.

A schematic diagram of a DFIG-based wind generator model is shown in Fig. 2. The stator is connected to a three-phase grid, and the rotor side is fed with a back to back pulse wide modulation based voltage source inverter with a standard DC connector. The supply side converter controls the flow of power between the DC and grid connector while the power switch next to the rotor provides mechanical enjoyment. The supply side converter operates at a grid frequency, whereas, the rotor-side converter at different frequencies depending on the speed of the blades. The converter is installed as a current source with d-axis rotor current and q-axis rotor current as a variable, and these variables are used for rotor speed and voltage control. DFIG-based flexible model. The wind generator is made up of the following components: wind speed model, aerodynamic model, voice angle control model, driving machine model, and DFIG model. The wind speed model is made up of four parts: basic wind, storm, outflow wind and random air.
