摘要： 由于新能源发电存在波动性和间歇性，其大量接入时会给电网运行带来新的困难，而利用储能技术提高新能源的可调度性是当前研究的热点。为缓解新能源并网对电力系统的不良影响，针对并网型风储微网提出了一种基于飞轮储能阵列系统的分层优化控制方法，上层优化中心根据功率缺额和各台飞轮的转速建立相应充/放电优化模型，并求解相应飞轮的功率参考值；下层飞轮控制器采用双模双环控制方法，实现飞轮转速和输出功率的控制，最后通过MATLAB/Simulink仿真验证了所提控制方法的有效性和可行性。

Abstract: Due to the fluctuation and intermittent nature of renewable energy, they massive access will bring new difficulties to the power grid operation. Improving the scheduling of renewable energy by using energy storage technology is the focus of current research. In order to mitigate the bad effect of renewable energy generation on power grid, a layered optimal control method based on flywheel energy storage array is proposed for grid-connected wind-storage microgrid. The upper optimization center establishes the corresponding charge/discharge optimization model according to the power shortfall and the speed of each flywheel, and solves the power reference value of the corresponding flywheel. The lower flywheel controller adopts dual-mode double loop control method to realize the control of flywheel speed and output power. Finally, the effectiveness and feasibility of the proposed control method are validated by MATLAB/Simulink simulation.
