Design of hybrid multilayer systems to improve energy management system in multi-microgrid systems in the presence of wind and solar power

Abstract

Connecting microgrids has some benefits such as operation cost reduction and increasing sales revenue of their owners. To exploit these benefits, an energy management system with diverse and efficient capabilities is required. In this paper, a multi-layer system has been proposed to improve the energy management system in multi-microgrid systems. The purpose of the multilayer system is to optimize the cost of energy supply for the producer with the ability to activate one or more layers to improve the energy management system. Layers are modules that may contain the data required for optimization, like generation volume, load consumption, and operational plan. The appropriate mathematical model of the proposed seven-layer structure is used to optimize the operation cost of the multi-microgrid system. To verify the performance of the energy management system, the proposed method is implemented by GAMS and MATLAB software and the results are analyzed for a sample multi-microgrid system.
