Compound Voltage Control Based on Ramp Charging Algorithm

In this paper we come up with three-stage voltage control to solve the voltage overshoot, consist of OLTC (On-Load Tap Changer) BESS (Battery Energy Storage System) and PRPC (Photovoltaic Reactive Power Control) to strengthen control capability. As the amount of home energy storage increases, SOC (State Of Charge) unified management becomes more and more complicated. Therefore, slope charging algorithm is proposed to unify SOC, simplify management and extend battery life. Experiments show that this method can improve the quality of power grid effectively and simplify the SOC management process in the later stage.
