Research on Development and Upgrade of Distribution Network Planning Technology

Recently, the distribution network has faced a situation of persistent improvement of clean energy penetration rate, continuous application of energy storage technology and rapid development of diverse loads such as electric vehicles. The new situation has put forward higher requirement for distribution network planning. This paper summarizes and analyzes the development and upgrade of distribution network planning technology from the perspectives of conventional distribution network planning, planning of clean energy access to the grid, and planning of regional integrated energy system. The scope covers load forecasting, distributed generation forecasting, location and capacity of distributed energy resources, network planning, technical and economic evaluation, and so on. And it is expected to provide some reference for relevant research and engineering applications.
