Open loop distribution network power flow simulation method based on multi-agents

Abstract

The invention relates to a simulation method in the technical field of electric power system simulation, in particular to an open loop distribution network power flow simulation method based on multi-agents. According to the method, a feeder line section is divided into a bus feeder line section, a load feeder line section and a terminal feeder line section, different agent models are respectively built, meanwhile, the content formats of information packets and the information exchange ruler and mode among the agents are determined; after different agents are initialized, the calculation finishing rulers of each agent are set, each agent receives the information packets and carries out calculation, the calculation stops after the rulers are met, and finally, distribution network power flow simulation calculation results are obtained. The method has the advantages that the physical principles of each key element equipment in a distribution network are simulated, the simulation method can be applied to distribution systems with the complicated structure, the whole topological analysis storage on a distribution network is not needed, in addition, PV (peak voltage) nodes can be easily processed, for the large-scale complicated distribution system in the future, the requirements of a plurality of control centers and calculation implementation can be met, and the power flow simulation analysis capability of a management system is greatly improved.
