PROJECT TITLE :

Solution to short-term frequency response of wind farms by using energy storage systems

ABSTRACT:

The increasing high penetration of wind power is bringing a significant challenge to the frequency regulation of Power System, for wind turbine generators are unable to naturally contribute to system frequency response. To deal with this problem, this study proposes a control strategy to compensate the lack of short-term frequency response ability of wind farms (WFs) by the energy storage system (ESS). Initial, the rated power and capability of the ESS, which is put in at the point of common coupling of the WF to create it have similar short-term frequency response ability to that of synchronous generators, are determined. The theoretical minimum rated power of the ESS should be regarding fivepercent rated power of the WF, solely if the active power output of the ESS is controlled as its rated power during the entire inertial response process. Then, a fuzzy logic controller is meant for the ESS therefore that the desired rated power of the ESS might reach its theoretical minimum value as closer as possible. Simulation results of a simplified practical Power System show that WFs with the proposed strategy could response to the frequency modification rapidly and support short-term frequency control effectively underneath various disturbances.
