摘要/Abstract

摘要： 随着电力系统中可再生能源比例的不断提高,在梯级水电站中引入抽水蓄能及电化学储能可有效提高风光消纳。针对不同风光比例下系统最优容量配置的变化情况和各设备的运行情况,构建风电-光伏-梯级混合式抽水蓄能-电化学储能联合系统,首先以经济性最优为目标对并网型联合系统进行最优容量配置并分析各设备的运行情况;其次分析不同风光比例对系统最优容量配置的影响;最后相较于并网型联合系统,对比分析离网型联合系统在不同风光比例下最优容量配置的变化情况。结果表明：随着风光比例升高,风光电逐渐承担主要负荷需求,而梯级混合式抽水蓄能电站水轮机容量减小、电化学储能容量迅速增大以满足系统对储能设备的需求,且相较于离网系统,并网型联合系统在兼具供电独立性的情况下更具有灵活性。

Abstract: With the increasing proportion of renewable energy in the power system, the introduction of pumped storage and electrochemical energy storage in the cascade hydropower station can effectively improve the wind and solar energy consumption. A combined wind power-photovoltaic-terrace hybrid pumped storage-electrochemical energy storage system is constructed. Firstly, the economic optimization is taken as the goal to make the optimal capacity configuration of the grid-connected combined system and the operation of each equipment is analyzed. Secondly, the impact of different wind and solar proportions on the optimal capacity configuration of the system is analyzed. Finally, the change of optimal capacity configuration of the off-grid combined system with different wind and solar proportions compared with the grid-connected combined system is analyzed. The results show that, as the proportion of wind and solar power increases, wind and solar power gradually takes up the main load demand, while the turbine capacity of the cascade hybrid pumped storage plant decreases, and the capacity of the electrochemical energy storage increases rapidly to meet the system demand for energy storage equipment. Compared to off-grid systems, grid-connected combined systems are more flexible with both power supply independence.
