说明：  微电网能量平衡的基本任务是指在一定的控制策略下，使微电网中的各分布式电源及储能装置的输出功率满足微电网的负荷需求，保证微电网的安全稳定，实现微电网的经济优化运行。
(The basic task of micro grid energy balance is to make the output power of each distributed power source and energy storage device in micro grid meet the load demand of micro grid under certain control strategy, ensure the safety and stability of micro grid, and realize the economic and optimal operation of micro grid.)
