This paper aims at the design and testing of a wind mill based power generation and distribution. The main concern in this project is to ensure that the reactive power generated throughout distribution line is reduced. This occurs due to the non-linear type of load. These types of loads are common in electronics devices such as; laptops, printers, chargers, LED TVs, etc. All these types of loads consist of rectifiers which necessarily convert the domestic alternating voltage to direct voltages. This induces a reactive power due to the lagging of current behind the voltage. Hence, in this project addressing the effects of non-linear loads becomes vital. This paper is applicable to microgrid composed of BESS (Battery energy storage systems), distributed generators (DGs), and Loads. DG is realized using wind mills. The theory and method of active and reactive power coordinated control before wind speed fluctuations were proposed based on the PQ transforms and hysteresis band controller where the control system is designed to reduce the power loss due to the reactive powers. The simulation has been done to improve the power quality in terms of real power. This is achieved by increasing the total power produced by the wind mill (keeping the reactive power same). Simulation results show that the controllers can extract maximum power and regulate the voltage and frequency under varying wind and load conditions. The controller shows very good dynamic and steady-state performance. The simulations had been done with MATLAB ver 2018a using power systems and simscape tool boxes available in Simulink library.
