Evaluation of the Credible Capacity of Wind Farms Considering Energy Storage

Abstract

Credible capacity in measure the value of intermittent power supply connected to the power system is of great significance. In this paper, we've established the probability model of the wind power, and given the operational characteristics of the energy storage device, it proposes a strategy of storage control, and then proposes a credible capacity calculation method for a wind-generated unified generator system. Using the non-sequential Monte Carlo simulation framework, based on the proposed savings and control strategy, it evaluates the effect of the storage capacity on the capacity of the wind power system. The effectiveness of the evaluation algorithm is tested by using the RTS-79 reliability example, and the results show that the proposed method can be used to evaluate the planning scheme of wind storage power generation system.
