Wind farm energy storage configuration

What is wind farm energy storage capacity optimization?

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.

How to reduce the cost of energy storage in wind farms?

Considering whole-life-cycle cost of the self-built energy storage, leasing and trading cost of the CES and penalty cost of wind abandonment and smooth power shortage, an optimal configuration model of combined energy storage capacity in wind farms based on CES service was established to minimize the total annual cost.

Do wind farms lease CES based on energy storage capacity configuration?

Through theoretical analysis and case studies, the following conclusions can be drawn: This paper designs an architecture of wind farm configu-ration system based on CES. Wind farms lease CES and participate in energy trading mechanism, so as to reduce the input cost of energy storage capacity configuration and suppress wind power fluctuations.

Do wind farms need energy storage capacity?

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.

What is the capacity of a wind farm?

Through Table 3 analysis, when there is only one wind farm in the alliance, the capacity of the energy storage facilities required by the wind farm 3 is the largest, with a capacity of 80 MW/h, followed by the capacity of the energy storage power station configured only by the wind farm 2, which is 78MWh.

How CES can help a wind farm?

The CES operator can aggregate idle energy storage capacity and invest in a portion of centralized energy storage devices to provide energy storage leasing service. Wind farms can lease CES to suppress wind power fluctuations, which brings new problems of energy storage capacity configuration.
