Abstract

This paper proposes the behavior of the hybrid renewable energy system, HRES, without and with pitch angle control during the variation in frequency. The HRES is a wind/PV one. The WG is based on a double fed induction generator (DFIG) when the rotor side converter (RSC) is used to connect the DFIG to DC bus voltage, put with a PV generator. The integration of the HRES in the grid introduces some problems such as the stability of the system and the quality of the injected power. This paper aims is to evaluate the ability of the HRES to remain connected to the grid following some disturbance, such as frequency variations. That is why the HRES will have to participate in primary frequency control. The only method of involving the HRES in the primary frequency control is to reduce the wind power captured by the wind turbine in order to increase the power in the event of a frequency drop. Simulation results prove that the pitch angle control can keep the HRES connected to the grid during the frequency variations.
