摘要: 针对光伏配储系统在电力市场多场景调度中的耦合问题,提出一种多场景优化调度策略。首先,基于光伏出力的不确定性分析,构建储能平抑光伏波动的模型。其次,结合电价不确定性,提出储能系统参与电力市场的调度策略。最后,通过多时间尺度的优化调度框架,综合考虑平抑光伏波动、电能量市场收益和调频市场收益的目标,优化储能系统的充放电计划。仿真结果表明,所提出的策略能够有效平抑光伏波动,并在电能量和调频市场中实现经济收益的最大化。具体而言,储能系统在平抑光伏波动的同时,通过低储高发的策略在电能量市场中获利,并在调频市场中提供灵活的辅助服务,显著提升了系统的经济性和稳定性。

Abstract: In order to solve the coupling problem of PV distribution and storage system in multi-scenario scheduling in power market, a multi-scenario optimal scheduling strategy is proposed. Firstly, based on the uncertainty analysis of photovoltaic output, a model of energy storage to stabilize photovoltaic fluctuations is constructed. Secondly, combined with the uncertainty of electricity price, the scheduling strategy of energy storage system to participate in the power market is proposed. Finally, through the optimal scheduling framework of multiple time scales, the charging and discharging plan of the energy storage system is optimized by comprehensively considering the goals of stabilizing photovoltaic fluctuations, electric energy market income and frequency modulation market income. The simulation results show that the proposed strategy can effectively stabilize the fluctuation of PV and maximize the economic benefits in the electric energy and frequency modulation markets. Specifically, the energy storage system not only stabilizes the fluctuation of photovoltaic, but also makes a profit in the electric energy market through the strategy of low storage and high generation, and provides flexible auxiliary services in the frequency modulation market, which significantly improves the economy and stability of the system.

Key words: photovoltaic power generation, energy storage system, optimal scheduling, electric energy market, frequency modulation auxiliary service, fluctuation stabilization
