Research on a Comprehensive Optimization Modeling Method for Power Transfer of Substation Microgrid

Under the background of energy internet, high elastic distribution network can improve the economy and reliability of the system by configuring various sources, loads and storage resources. For the high-elastic distribution network with controllable distributed micro-sources, demand-side management resources and energy storage resources connected to the microgrid, the optimal load transfer model under fault conditions is established considering the call of source-load-storage resources. The established model takes into account the call cost of source-load-storage resources and takes the minimization of the comprehensive loss of power load during the fault period as the objective function. At the same time, the establishment of the model also takes into account the necessary constraints such as Branch circuit capacity constraints, system power balance constraints, node voltage constraints, and Unit output power constraints. Finally, the validity and correctness of the model are verified by formulating the load transfer scheme for a high-elastic distribution network based on IEEE33 standard node system under fault conditions.
