Abstract - The generator acts as the primary component in
concentrations of greenhouse gases, which are incredibly harmful to our planet. When compared to other sustainable power sources, wind energy has emerged as a viable solution for generating clean energy and is now the source that is developing the fastest. However, the usage of the energy that is available is dependent on the weather (wind speed), and its integration results in volatility in the power system. The generation of power and the reduction of CO2 could change as a result of the integration of renewable energies with network connectivity, intelligent control, and storage systems. The worldwide energy storage has previously conducted an analysis of the need for a 100% renewable electricity supply [2,3]. The author of International Electrotechnical Commission claims that advances in smart grids and rising use of renewable energy are to blame for the demand for energy storage [4]. Renewable energy sources (RESs) are predicted to be able to supply 70% of the world's energy requirements by 2050. The most significant energy sources will be wind, solar, and storage technologies. The utilisation of these alternative energy sources reduces dependence on fossil fuels and greenhouse gas emissions in the electrical industry [5]. The majority of nuclear and fossil fuel sources will also be totally replaced, with wind energy likely being the most prevalent and the first viable power of a worldwide energy system. Numerous academics are currently interested in initiatives to increase and improve the wind sector's participation in the power generation industry [6]. A squirrel-cage induction generator (SCIG), a doubly fed induction generator (DFIG), and a direct-drive synchronous generator (DDSG) are a few examples of the several types of generators utilised in the wind power industries [7–9]. The advantages of DFIG include its ability to independently manage active and reactive power output, a tiny power converter rated at 30% of the generator to handle the rotor power for excitation, and the capacity to control terminal voltage via reactive power control. The main cause of problems in WT is faulty generators. The generator, which is a key element in a wind turbine and is responsible for converting the mechanical energy of the wind into electrical energy, is the heart of the wind turbine. The costs of operation and maintenance will rise as a result of the rapid breakdown in WT. Therefore, a fault investigation of the generator model in the wind turbine is required to learn the specific characteristics in order to avoid the generator from breaking. The majority of WT
a wind turbine (WT) system since it transforms mechanical energy into electrical energy. Most wind turbine malfunctions are caused by an unreliable generator. As a result, it is now more important than ever to understand the specific characteristics of the generator in wind turbines in order to avoid errors. The objective of this paper is to create a mathematical model of a wind turbine generator that is simply changeable to apply any generator fault for the research of the dynamic WT system. This is because the majority of developed WT models are either too simplistic in generator modelling or have intellectual property protection. MATLAB/Simulink was used in this research to create the mathematical model of the induction generator based on a wind turbine. The wind turbine model that was built comprises of an induction generator model, an aerodynamic model, and a wind turbine drive train based on two mass models. Electrical equations in Park's reference frame served as the basis for the development of the induction generator. Electrical and mechanical subsystems make up the model. The proposed model of the wind turbine with an induction generator was then verified using a thorough MATLAB model of a wind farm with a doubly-fed induction generator (DFIG). Comparisons were made between the two models' simulated responses for mechanical torque, electrical torque, generator speed, and power. The outcome demonstrates that both WT models' simulated responses shared the same waveform shape and dynamic behavior due to variable configuration or rating.

1. INTRODUCTION The need for the generation of renewable energy is increasing in recent years due to social and environmental reasons, such as climate change and the dangers of fossil fuels. Given this increase in demand, a number of nations, including China, the USA, and Europe, have demonstrated the efficiency and cleanliness of producing electricity from wind turbine systems [1]. Globally, the advancement of renewable energy in contemporary production power systems has multiplied due to the rise in atmospheric
