The goal of wind farm energy storage capacity optimization is to meet the constraints of smooth power fluctuations and minimize the total cost, including the cost of self-built energy storage, renting CES, energy transaction service, wind abandonment penalty and smooth power shortage penalty.
Considering the economic benefits of the combined wind-storage system and the promotion value of using energy storage to suppress wind power fluctuations, it is of great significance to study the optimal allocation of energy storage capacity for wind farms.
According to , 34 MW and 40 MW h of storage capacity are required to improve the forecast power output of a 100 MW wind plant (34% of the rated power of the plant) with a tolerance of 4%/pu, 90% of the time. Techno-economic analyses are addressed in , , , regarding CAES use in load following applications.
Currently, research on the control of wind power and energy storage to participate in frequency regulation and configuration of the energy storage capacity is at its nascent stage. Similar to wind generators, energy storage can be involved in system frequency regulation through additional differential-droop control.
Wind farms can lease CES to suppress wind power fluctuations, which brings new problems of energy storage capacity configuration. Therefore, it is urgent to study the joint optimal configuration of leased CES capacity and self-built physical energy storage capacity.
Energy Storage Systems (ESSs) may play an important role in wind power applications by controlling wind power plant output and providing ancillary services to the power system and therefore, enabling an increased penetration of wind power in the system.
