Optimal Power Sharing Control of Wind Turbines

Abstract

Wind generation can significantly disturb the power balance within particularly a weak power grid such as stand-alone microgrids. To counterbalance the impacts, an optimal power sharing control scheme that seeks to cope with the power dispatching demand by system operator is proposed for DFIG wind turbines. The control scheme can fulfill the dispatching command via maximizing the rotational kinetic energy stored in DFIGs, which can be later released for system support when needed.
