TY - JOUR ID - TI - MAXIMUM POWER COEFFICIENT CONTROL OF A MICRO GRID-CONNECTED WIND ENERGY SYSTEM AU - Kassim A. Al-Anbarri AU - Ali Jafer Mahdi AU - Mustafa M. Atiyah PY - 2022 VL - 26 IS - 2 SP - 56 EP - 66 JO - Journal of Engineering and Sustainable Development (JEASD) مجلة الهندسة والتنمية المستدامة SN - 25200917 25200925 AB - This paper proposed the integration of the wind energy system (WES) with the grid consists of a wind turbine, a permanent magnet synchronous generator (PMSG), a switch-mode rectifier (SMR) and a three-phase voltage source inverter (VSI). Optimal torque control (OTC) method is applied to the converter on the generator side for maximizing the power coefficient under the change in wind speeds. To synchronize the WES with the grid, another controller is applied to keep dc-bus voltage at constant value and to regulate active and reactive power transmitted into a grid. A system of WES connected into a grid is created and tested in the MATLAB/SIMULINK platform version 2019b. Comprehensive simulation results are used to analyze and verify the excellent performance of the suggested two- control strategy on the machine and grid side.
