Distributed energy management and communication strategy for network of microgrids
The increasing integration of renewables, battery storage, and electric vehicles is leading communities to operate as microgrids within distribution networks. Managing multiple microgrids as a network of microgrids enhances benefits of individual microgrids. Although there are different approaches for energy management system of network of microgrids in the literature, this work presents a distributed communication approach for the energy management of network of microgrids by considering that each microgrid has a communication network with a limited number of participants, i.e., the communication network of each microgrid does not cover all other microgrids. The proposed method is compared to the centralized approach. In the test cases, the collective operational cost of microgrids are reduced from 1070$ to 54$, which corresponds to a cost reduction 93% of that achieved by the centralized approach. The results show that the proposed method can serve as an alternative to the centralized version considering investment costs and resilience. A simulation test case illustrates the indirect communication between two microgrids through a common neighbouring microgrid. Despite performing well, the proposed approach cannot surpass the centralized energy management system as expected. Furthermore, a scenario featuring an undesirable power transfer route is presented as a limitation case.
期刊介绍:
Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview.
• Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation.
• Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design.
• Substation work: equipment design, protection and control systems.
• Distribution techniques, equipment development, and smart grids.
• The utilization area from energy efficiency to distributed load levelling techniques.
• Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
