PROJECT TITLE :

Ramp Event Forecast Based Wind Power Ramp Control With Energy Storage System

ABSTRACT:

Wind power ramp events became one of the major challenges of power balance in power systems with high wind power penetration. Conventional thermal or hydro units should be dispatched, close up or started up additional frequently to keep the balance between generation and load. This paper proposes a wind power ramp management method with energy storage system (ESS) based mostly on wind power ramp event forecast. An optimization model is established to optimize the output power of ESS and also the wind curtailment to satisfy a hybrid wind power ramp limit. Three varieties of wind power ramp situations are presented based on the ramp event forecast, as well as traditional scenario, positive ramp eventualities, and negative ramp scenarios. In every scenario, the optimization model is modified with scenario switching adjustment (SSA) to scale back the capacity demand of ESS and therefore the curtailed wind energy. Whereas the parameters for modification are obtained by completely different fuzzy logic systems (FLS). Finally, the effectiveness of the proposed wind power ramp control method is verified through case studies.
