Analysis of typical configuration scheme of micro-grid based on the electric energy router

The electric energy router (EER) could provide more flexible control means of power flow for micro-grid. In this paper, we focus on the key issues of micro-grid configuration. First, 3 typical micro-grid configurations based on EER are proposed. To assess the typical configuration schemes, 4 kinds of assessment indexes are introduced, which include local consumption capacity of renewable energy, energy loss, operation cost and Life Cycle Cost (LCC) of micro-grid. A thorough analysis for these configuration schemes based on the typical scenarios has been carried out. Then the impact factors on the configuration are investigated in the assessment and the conclusions could be the useful references for optimizing configuration of micro-grid based on ERR.
