Performance study on pmsg based grid connected wind energy conversion system with non linear feedback controllers

Abstract

People around are abundantly worried about the non-renewable energy source depletion and the ecological issues caused by the conventional power generation. So people are moving to renewable power sources and among them Photovoltaic Boards and wind-generators are broadly utilized at present. Wind sources are used today in numerous applications, for example, battery charging, water pumping, home power supply, swimming-pool heating frameworks, satellite power frameworks, and so on. They have the benefit of being support and contamination-free, however, their establishment cost is high in many applications. The share of wind power concerning the total installed power capacity is increasing worldwide. The Permanent Magnet Synchronous Generator (PMSG) based wind turbine with a variable-speed variable-pitch control scheme is the most popular wind power generator in the wind power industry. This machine can be operated either in grid-connected or standalone mode. A thorough understanding of the modeling, control, and dynamic as well as the steady-state analysis of this machine in both operation modes is necessary to optimally extract the power from the wind and accurately predict its performance. The strategies differ in complexity, sensors required, combination speed, cost, the scope of effectiveness, usage equipment, popularity, and in various regards. To mitigate the issues, different control calculations are produced to accomplish maximum power from the Wind Energy Conversion System (WECS) under variable speed conditions. In this work, the three advanced methods are proposed to dynamic characterises from the WECS integrated grid. In the first method is Firefly Algorithm (FA) and Artificial Neural Network (ANN) algorithms are used to attain the optimal pulses of cascaded H-bridge multilevel inverter. With optimized design parameters, the grid integrated power system design attained a voltage THD of 11.47%. newline
