摘要/Abstract

摘要： 本文研究了并联到同一直流母线的飞轮储能阵列协调控制策略，对经典的3种功率控制策略下的荷电状态（SOC）变化率进行了推导和分析，提出改进系数的下垂控制策略，同时针对微网电压低、阻抗小引起的静态误差控制问题，采取引入虚拟阻抗的改进系数下垂控制策略进行补偿，从而改善了系统功率分配精度。最后建立了含风电场的微电网模型，仿真验证上述控制策略的有效性。

关键词: 飞轮储能阵列, 荷电状态(SOC), 微电网, 协调控制, 下垂控制

Abstract: The coordinated control strategy of flywheel energy storage array from parallel to the same DC bus is studied in this paper. The change rate of charge state (SOC) under three classical power control strategies is deduced and analyzed. An improved coefficient droop control strategy is put forward. The virtual impedance of improved coefficient droop control strategy is adopted to improve the accuracy of power allocation to solve the static error control problem caused by low voltage of micro-grid. Finally, a micro-grid model with wind farm is established, and the effectiveness of the above control strategy is verified by simulation.

Key words: flywheel energy storage array, state of charge, micro-grid, coordinated control strategy, droop control strategy
