Aiming at the problems of increased operating cost
insufficient line capacity and high operating risks caused by short-term peak loads after distributed photovoltaic is connected to the distribution network
a two-layer planning method of distribution network including distributed power is proposed considering the influence of short-time peak load. The upper-layer planning model is based on particle swarm optimization algorithm
and takes PV
energy storage cost
location and line expansion planning cost as the objective function to solve the problem. The lower-layer planning model uses self-organizing mapping method to select typical days of different load types and takes the minimum daily operating cost of distribution network as the objective function to solve the problem. Then
using the established two-stage planning method
taking the IEEE33-node distribution network system as an example
the influence of short-time peak load on the distribution network is analyzed. Finally
through scenario comparison
the necessity of considering the impact of short-term peak loads is further verified.
