Photovoltaic power generation has certain volatility and uncertainty,weather,seasons and other factors will lead to changes in photovoltaic power,the energy storage system needs to track,forecast and adjust in real time to maintain the balance of supply and demand,but volatility and uncertainty increase the complexity of control.Therefore,a new adaptive coordinated control method for distributed energy storage capacity is proposed.Calculate the reactive power loss of energy storage after a high proportion of photovoltaic energy is added,and set power constraints to ensure power stability.Based on this,the optimal voltage condition,the lowest access load and net power,and the optimal power adjustable range at the high proportion photovoltaic access point are taken as the regulatory goals,and the adaptive coordinated control of distributed energy storage capacity of high proportion photovoltaic access is realized.Experimental data prove that the proposed method has significant advantages in terms of control effect,and can realize efficient distributed energy storage control and ensure efficient photovoltaic output.
