Abstract:


This paper deals with power control of a wind and solar hybrid generation system for interconnection operation with electric distribution system. Power control strategy is to extract the maximum energy available from varying condition of wind speed and solar irradiance while maintaining power quality at a satisfactory level. In order to capture the maximum power, variable speed control is employed for wind turbine and maximum power point tracking is applied for photovoltaic system. The grid interface inverter transfers the energy drawn from the wind turbine and PV array into the grid by keeping common dc voltage constant. To ensure safety these inverters automatically shut down in the event of : High/Low grid AC-voltage; High/Low grid frequency; Grid Failure; or Inverter malfunction. Modeling and simulation study on the entire control scheme is carried out using a power system transient analysis tool, Matlab Simulink. The simulation results show the control performance and dynamic behavior of the wind/PV system.
