中文说明：
针对带储能的光伏系统出力不稳定问题，基于储能变流器提出了一种带有灰色补偿的Back-stepping控制方法，以实现对并网点上层规划层面有功功率P和无功功率Q指令的跟踪控制，同时保证并网点电压的稳定。
English Description：
Storage of photovoltaic system output associated with unstable problem, based on the energy storage converter is proposed with a grey Back - stepping control method of compensation, in order to achieve the upper planning level and branch active power P and reactive power Q order tracking control, at the same time, guarantee and node voltage stability.
