双碳目标下我国配电网形态快速演进的思考OA北大核心CSTPCD

Many countries are promoting energy transformation.Due to the rapid development of new energy and the improvement of electrification of terminal energy consumption,the form of distribution network is gradually evolving.The distribution network in China faces multiple missions of making up for shortcomings,supporting demand growth and promoting energy transformation,and the time span from carbon peaking to carbon neutrality is only 1/2 of that of developed countries,so the evolution of the distribution network form is more drastic.This paper proposes an analysis method based on three scenarios of city,park and rural areas,and three forms including network architecture,technical control and commercial operation.It considers the driving force,path and goal of the form evolution of distribution network under three scenarios separately.The urban distribution network will evolve towards"distribution power system dominated by the large power grid with flexibly regulated load,and flexibly configured new energy storage".The park distribution network will evolve towards"comprehensive energy system supported by large power grid and multi-energy complementary".The rural distribution network will evolve towards"a new type of local power system led by distributed new energy and energy storage and inter-connected with large grid".The relevant stakeholders including government,industry,research and users should establish systematic thinking and apply systematic methods to coordinate source,network,load and storage to promote the planning,construction and operation of the distribution network in an orderly and friendly manner.
