Abstract

Abstract: Microgrid group is a direction of future microgrid connection. Our research group has proposed an intelligent structure adaptive to the large-scale application of microgrid， which is called honeycomb active distribution grid. This paper studies its optimal scheduling problem. Firstly， active microgirds and smart power/information exchange stations in the topology are explained. Secondly， the distributed optimization method based on the consistency constraint is used to decompose the grid into several parts， and the mathematical model of the honeycomb distribution grid is derived. Next， considering the economic and reliability， the minimum operation cost is selected as the optimization target， and the MATLAB/YALMIP/IPOPT business solver is used to solve the optimized model. Finally， a honeycomb active distribution grid consisting of seven microgrids is taken as an example to illustrate the optimized model and solution method. The effects of the honeycomb distribution grid on the economy and reliability of the microgrid group are analyzed.

Key words: honeycomb active distribution grid, smart power/information exchange station, distributed optimization, consistency constraints
