Analysis and Quantification of the Impact of Energy Storage on Wind Power Utilization

Energy storage plays a significant role in accommodating the rapidly increasing wind power in power system, and its two important parameters, maximum charging/discharging power and total capacity, have important impacts on wind power utilization. In this paper, we propose two characterization models to quantify the relationship between wind power curtailment rate and energy storage parameters, in the sense of expectation and robustness for wind uncertainty. By adopting typical wind power scenarios and duality theory, the original characterization models are reformulated into a series of linear programs with different parameter sets for efficient solving. Case studies demonstrate the effectiveness of the proposed models and methods.
