Reactive Voltage Control Strategy of Distributed Generation with High Proportion Access to Distribution Network

With the vigorous development and utilization of new energy, the amount of distributed photovoltaic access in the distribution network has increased significantly, and it has also brought a series of problems when it brings convenience to users. Among them, because the distributed photovoltaic grid-connected changes the power flow characteristics of the traditional distribution network, more and more high-proportion distributed photovoltaic access makes the phenomenon of voltage over-limit more prominent, and brings higher network loss power. Therefore, this paper uses PSO to perform VVO on the active distribution network to eliminate voltage problem and explore the minimum network loss under the voltage range. Finally, this paper uses the IEEE33 node typical distribution network system to eliminate the over-limit problem PV in the distribution network within 0–48 h and find the minimum network loss.
