Comprehensive Controller Implementation For Wind-pv-diesel Based Standalone Microgrid

In this project we are integrating three types of renewable energy sources (RES) which are Solar photovoltaic (PV) system, Wind energy system (WES) and  a diesel generator connected to a  Standalone Micro-grid. This Micro-Grid is controlled by a   active power control based on proportional-integral controller with anti-windup, is used for voltage and frequency regulation.   The LCL filter based on virtual resistor, is used for power quality improvement at PCC.  And , to ensure perfect synchronization of a diesel generator to the point of common coupling (PCC), a control algorithm is developed, which is based on in-phase and quadrature units.  The power ratio variable step perturb and observe method is applied to achieve maximum power point tacking of a solar photovoltaic array and a variable speed wind turbine coupled a permanent magnet brushless DC generator without rotor/wind speed sensors.  Simulation and test results are presented for the validation of proposed system.
