摘　　要：随着我国“双碳”政策的稳步推进,以风电、光伏为代表的可再生能源大规模并网。储能技术能够解决新能源出力的间歇性以及功率波动等问题,提出一种飞轮储能(flywheel energy storage,FES)和电池储能(battery energy storage,BES)相结合的方式进行调度。建立混合储能系统(hybrid energy storage system,HESS)的优化调度模型,其次采用非线性规划方法进行求解,最后结合实际算例进行验证。结果表明,在保证各类储能技术的工程总成本、运维成本最小和生命周期的基础上,通过考虑FES和BES的斜坡速率,实现了HESS的2种内部储能技术的最优功率分配。With the steady advancement of China's dual-carbon policy,renewable energy sources represented by wind power and photovoltaic have been connected to the grid on a large scale.Energy storage technology can solve the problems of intermitent output of new energy sources and power fluctuations.A combination of flywheel energy storage(FES)and battery energy storage(BES)is proposed for scheduling.The optimized scheduling model of hybrid energy storage system(HESS)is established,the nonlinear planning method is used to solve it and verified in combination with actual examples.The results show that on the basis of ensuring the total engineering cost,minimum operation and maintenance cost and life cycle of various energy storage technologies,the optimal power distribution of the two internal energy storage technologies of HESS can be realized by considering the slope rate of FES and BES.
