This paper examines an improved dual-battery energy storage scheme designed to achieve wind power dispatchability. The capacity of the battery energy storage system is greatly reduced by allowing direct power flow from wind turbine generator to the grid via a dc bus, as the two batteries interchange their charging and discharging roles at specific time. The method to determine the optimal capacity...
A dispatch strategy is proposed for the purpose of maximizing the income for a wind turbine - dual battery energy storage power station. The strategy takes into consideration the complex relationship between the efficiency of the battery and the BESS discharge level while meeting the prevailing power market rules. The technique requires an accurate forecast in both the variable wind power and electricity...
The paper addresses a novel scheme for the control of variable wind energy and energy storage plant such that the generation and energy storage can deliver a smooth and constant power as demanded by the grid load. In addition, the wind energy generators are assumed large compared to the local grid rating and will contribute to the voltage and frequency regulation of a grid using adaptive frequency...
This paper investigates embedding Energy Storage (ES) with multiple wind turbines in order to deliver to the grid a smooth and constant power as demanded by the system operator. The demand power is shared by DFIGs proportional to their ratings utilizing classical voltage and frequency droop characteristics. The paper addresses the system control methodologies for delivering constant power to the grid...
