Photovoltaic group string side battery energy storage adaptive coordination power distribution method

The invention discloses a photovoltaic group string side battery energy storage self-adaptive coordination power distribution method, the output end of a photovoltaic group string is connected with a grid-connected inverter and an energy storage inverter, the grid-connected inverter realizes photovoltaic maximum power tracking and electric energy feeding into a power grid, and the energy storage inverter performs power distribution according to the photovoltaic output power and the battery charging stage. And the storage power value is adaptively adjusted, the maximum storage of photovoltaic electric energy is realized, meanwhile, photovoltaic curve characteristics are kept for a power curve of the grid-connected inverter, and photovoltaic maximum power tracking failure is avoided. 本发明公开了一种光伏组串侧电池储能自适应协调功率分配方法，伏组串输出端分别并网逆变器以及储能逆变器连接，并网逆变器实现光伏最大功率跟踪与电能送入电网，储能逆变器依据光伏输出功率以及电池充电阶段，自适应调节存储功率值，实现光伏电能最大存储，同时给予并网逆变器的功率曲线保持光伏曲线特征，避免光伏最大功率跟踪失败。
