Operating Policy of Short-Term Power Dispatch for a Wind Farm

This paper investigates diesel units (DU)-battery energy storage systems (BESS) scheme to enable short-term dispatch commitment from a grid-connected wind turbine generating power station.The scheme is supplied by two distributed resources (DR) units, i.e., a synchronous machine and an electronically interfaced BESS. An operating policy to schedule short-term power dispatch for the scheme based on wind power forecast of the next interval,load demand and the charging/discharging characteristics of BESS is proposed. The studies show that an appropriate control strategy which by tracking active currents of BESS can ensure an acceptable level of dispatch security while maximizing wind energy harness.
