摘要
风电汇集区域建设储能电站可在保证整个区域一次调频能力的同时提高经济性。针对风电汇集区域建设储能电站提出一种基于运营策略的储能容量配置方法。储能电站采用独立运营机制,在保证区域一次调频容量的前提下参与电力市场交易,实现储能利用率、效益最大化。提出储能电站运营配置协同优化双层模型,外层以全生命周期投资回报率最大为目标进行储能配置,内层计及储能循环寿命以日运行期望利润最大为目标优化运营策略,内外层联合优化达到综合最优,从而得出储能配置结果。提出一种改进麻雀搜索算法提高收敛速度,对双层配置模型进行求解。通过算例验证了所提方法能够在确保区域具备一次调频能力的同时提高储能的经济性。
The construction of energy storage power stations in wind power gathering areas can ensure the primary frequency modulation capability of the whole area and improve the economy at the same time.A storage capacity allocation method based on operational strategy is proposed for building storage power stations in wind power gathering areas.Energy storage stations use an independent operation mechanism to participate in power market transactions on the premise of ensuring the primary frequency modulation capacity of the region,so as to maximize the utilization rate and efficiency of energy storage.A two-tier model for collaborative optimization of operation configuration of energy storage power stations is proposed.The outer layer configures energy storage with the maximum return on investment in the whole life cycle as the target.The inner layer optimizes operation strategy with the maximum expected profit in daily operation as the target considering energy storage cycle life.The outer and inner layers are optimized to achieve comprehensive optimization,so as to get the result of energy storage configuration.An improved sparrow search algorithm is presented to improve the convergence rate and analyze the two-level configuration model.An example shows that the proposed method can improve the economy of energy storage while ensuring the primary frequency modulation capability of the region.
