Routing Control and Fault Recovery Strategy of Electric Energy Router Under the Framework of Energy Internet

Abstract

The inclusion of advanced technologies such as emerging energy internet and system perception via data fusion in the electric power systems enhances the overall performance and reliability of the power system. However, accurate path selection, congestion circumvention, and fault recovery in electric energy router (EER) within the emerging energy internet are the key challenges. This paper proposes the routing control strategy based on the minimum loss path (MLP) and the fault recovery strategy based on the multi-source cooperative power supply (MCPS) for accurate path selection, congestion circumvention, and fault recovery in electric energy router (EER). The proposed MLP strategy offers accurate path recognition having smaller power loss in congestion circumvention. Moreover, the MCPS strategy can guarantee the power supply of various loads and maximize the normal load to restore power during the fault. Meanwhile, two priority ranking methods, incentive reasonable quotation and incentive transaction volume realized by loss transfer, are proposed. Finally, the feasibility and superiority of the overall strategy are verified by simulation and comparison.
