摘　　要：为了有效抑制分布式发电输出的随机性、间歇性对大电网所产生的不利影响,提高分布式发电并网的功率协调控制,针对包含光伏发电、混合储能和卸荷器的微电网并网对大电网的冲击,提出了卸荷器和储能的微电网并网功率协调控制策略,在确保微电网系统向大电网提供指定的有功功率、无功功率的同时,避免混合储能单元因充放电功率过大而导致对自身的损害。通过Matlab/Simulink平台开展了仿真研究,仿真结果验证了协调控制策略的有效性。For the effective suppression of bad effects caused by the randomness and intermittence of distribution generation to the grid and to make the micro-grid system more grid-friendly, aimed at a micro-grid with photovoltat- ie/hybrid storage/dump load, a coordinated control strategy of grid-connected power for the micro-grid system with dump load and energy storage is proposed. It ensures that the micro-grid system can provide specified active power/ reactive power to the grid, at the same time avoid damage to the energy storage due its overlarge charging and dischar- ging power. The simulation is carried out through the Matlab/Simulink platform. The simulation results verify the va- lidity of the proposed coordinated control strategy.
