The control strategy of energy storage externality for reducing wind curtailment from wind farm cluster. (October 2018) - Mu, Gang
Abstract: Due to its flexible power regulation capability, energy storage is been considered as an efficient technology to reduce wind curtailment. However, since the fluctuation characteristics and low energy density characteristics of wind power, energy storage might be inefficient when reducing the wind curtailment from a single wind farm and the regulation capability of energy storage system (ESS) may not be fully utilized. Based on theoretical analysis the externality effect of energy storage is revealed in this paper, the control strategy of energy storage externality for reducing wind curtailment from wind farm cluster is established. By simulating analysis, the feasibility of the energy storage externality is verified. Moreover, by comparing with the conventional ESS control method, the paper evaluates the efficiency of the control strategy. The simulation results prove it can expand the influence scope of ESS and reduce more wind curtailment from wind farm cluster, the utilization of ESS is also promoted significantly.
