Abstract
Currently, some small islands with high wind potential are trying to reduce the environmental and economic impact of fossil fuels using its renewable resources. Nevertheless, the characteristics of these renewable resources negatively affect the quality of the electrical energy causing frequency disturbances, especially in isolated systems. In this study, the combined contribution to frequency regulation of variable speed wind turbines (VSWT) and a pump storage hydropower plant (PSHP) is analyzed. Different control strategies, using the kinetic energy stored in the VSWT, are studied: inertial, proportional, and their combination. In general, the gains of the VSWT controller for interconnected systems proposed in the literature are not adequate for isolated systems. Therefore, a methodology to adjust the controllers, based on exhaustive searches are proposed for each of the control strategies. The control strategies and the methodology have been applied to a hybrid wind-hydro power plant committed in El Hierro island in the Canary archipelago. At present, in this isolated power system, frequency regulation is only provided by the PSHP and diesel generators. The improvements in the quality of frequency regulation including the VSWT contribution have been proven based on simulating different events related to wind speed, or variations in the demanded power.
