Aiming at the problem that the whole network topology information of the new power system Internet of Things is managed in a decentralized manner by taking power plants and stations (including power plants, substations, renewable energy power plants, virtual power plant, etc). Firstly, a topology analysis method for power plants based on switch path function was proposed. Secondly, the rules for decentralized coordination of plant and station information were proposed, and an improved switch path function method for adjacent plant and station topology analysis was proposed, as well as a method for achieving full network topology analysis through plant and station decentralization. Finally, the feasibility of the proposed method was demonstrated through simulation of an actual new power system.
