考虑网络重构的微电网并/离网协同调度策略研究OA

A microgrid optimization scheduling model considering dynamic network reconstruction was proposed for the parallel and off grid scheduling problem of microgrids.The proposed model was based on Benders decomposition and decomposes the optimal scheduling problem of microgrids into a grid-connected operation master problem and an islanded operation subproblem.When the grid-connected operation scheduling plan cannot guarantee the feasibility of island operation,the network topology structure,unit output,and scheduling plan of energy storage and adjustable loads in the main problem can be dynamically adjusted to meet the relevant constraints of the subproblem.A new linearized power flow model for distribution networks that considers network reconstruction was proposed to support the solution of the proposed optimized scheduling model.A random framework based on unscented transform(UT)was introduced to make the proposed model more in line with the actual power grid situation.The effectiveness and superior performance of the proposed model were verified through simulation analysis of the IEEE33 node test network.
