Therefore, it is of great significance to study the voltage control strategy of a distribution network containing PV. The most traditional reactive power voltage control in distribution networks is to use reactive power resources such as transformer taps and capacitor banks [6, 7] for regulation.
The distributed energy storage and photovoltaic are connected at the same node. The total load of the system and the active output of photovoltaic are shown in Figure 8. Figure 6. Schematic of distribution network structure and distribution of photovoltaic-storage system. Figure 7. Installed capacity of PV vs. peak load power. Figure 8.
The above methods have mainly focused on consideration of distributed photovoltaic as a fixed power source, and the uncertainty has not been fully considered. In response to this, reference proposed a dynamic voltage control method for a distribution network based on distributed model predictive control.
First, the impact mechanism of PV access on the distribution network voltage needs to be further investigated; second, the regulation costs of photovoltaic and energy storage are different, and the effects of the control by different node powers on node voltage are also different.
