Optimization Strategy for Line Loss Reduction of Distribution Network Based on Multi-distributed Photovoltaic Access

The number of distributed photovoltaic power generation systems connected to the system is increasing, especially for residents and non-residents. A large amount of photovoltaic grid-connected power brings new problems to the line loss management of the distribution network. This paper proposes a theoretical calculation model of line loss for distribution network with multi-distributed photovoltaic access. This paper adopts the actual case of Shanghai Power Grid, calculates based on the mathematical model proposed, and puts forward targeted optimization suggestions by comparing the simulation analysis results.
