Abstract

The invention relates to a microgrid distributed communication topology design method based on graph theory connectivity, and the method comprises the steps: selecting candidate topological structureswith communication connectivity in a microgrid; obtaining algebraic connectivity, delay margin and communication cost corresponding to each candidate topological structure; obtaining performance index of each candidate topological structure, and selecting the optimal distributed communication topological structure corresponding to the maximum performance index; finally establishing distributed secondary voltage control of the microgrid based on the optimal distributed communication topological structure of the microgrid, and achieving reactive power equalization and average voltage recovery.The design method is based on the graph theory connectivity, and the convergence of secondary voltage control and delay robustness are used as performance indexes of the distributed communication topology, which provides the basis for the design of a distributed secondary control strategy and realizes reactive power equalization and average voltage recovery of microgrid, thereby improving the overall power quality of the microgrid.

Description

technical field [0001] The invention relates to a micro-grid distributed communication topology design method based on graph theory connectivity, and belongs to the technical field of micro-grid operation control. Background technique [0002] With the depletion of the earth's resources and people's attention to environmental issues, the access to renewable energy has attracted more and more attention from all over the world. Microgrid is an emerging energy transmission mode that increases the penetration rate of renewable energy and distributed energy in the energy supply system, and its components include different types of distributed energy resources (DER, including micro gas turbines, wind turbines, Photovoltaic, fuel cells, energy storage equipment, etc.), user terminals of various electrical loads and / or thermal loads, and related monitoring and protection devices. [0003] The power supply inside the microgrid is mainly responsible for energy conversion by power ele...
