【Abstract】 Multiple targets need to be considered in the day-ahead scheduling oriented to"source-grid"interaction,and optimization of multiple time periods needs to be carried out at the same time. Based on the analysis of the characteristics of interactive resources,an optimization method of the day-ahead scheduling of the smart distribution network is proposed on the basis of the matrix coding with minimum voltage offset,network losses,load fluctuations,and the number of switching opera-tions as objective functions. The output and terminal voltage of controllable distributed generation,the exchange power bet-ween micro grid and distribution network,and the switch states are used as control variables. The design of simulation examples is based on an 86-node distribution network and the effectiveness of the model and the algorithm is verified by the simulation results.更多还原
