摘要

针对光伏出力的波动导致户用光储系统能量优化不确定性的问题,提出了一种多时间尺度能量管理策略。在日前阶段,综合考虑分时电价、储能系统的寿命和负荷的可控性,建立了以用户用电成本、储能运行成本和环境成本最小化为目标的调度模型;在日内阶段,基于模型预测控制(model prediction control, MPC)并参考日前调度计划进行实时调度能量优化,矫正光伏出力的预测偏差,在不影响用户舒适度的前提下降低系统运行成本。最后,仿真结果验证了所提能量管理策略的经济性和有效性。

Abstract

A multi-time scale energy management strategy is proposed to solve the problem that the fluctuation of photovoltaic (PV) power leads to the uncertainty of energy optimization of household PV-storage system. In the day-ahead stage, considering the time-of-use price, the life of energy storage system and the controllability of load, a scheduling model with the goal of minimizing the user’s electricity cost, energy storage operation cost and environmental cost is established. In the inner-day stage, real-time scheduling energy optimization is carried out based on model prediction control (MPC) and reference to the day-ahead scheduling scheme to correct the forecast deviation of PV power, so as to reduce the operation cost of the system without affecting 
the user comfort. Finally, the simulation results verify the economy and effectiveness of the proposed energy management strategy.
