As the penetration rate of distributed renewable energy within microgrids increases,insufficient flexible resource scheduling leading to curtailment and loss of load will have a significant impact on the operation of microgrids. A microgrid day ahead risk scheduling strategy that takes into account source load correlation by fully scheduling various distributed flexible resources is proposed. Under the independent microgrid regulation architecture considering flexible resources,the Latin hypercube sampling method considering correlation is adopted to deal with the uncertainty of distributed photovoltaics and loads. The expected scheduling cost,loss cost of abandoned light and load,and conditional risk cost of microgrids under the influence of correlation are analyzed,and a day-ahead optimization scheduling model with the minimum expected total scheduling cost is constructed. The simulation results show that the proposed strategy can effectively balance the economic and operational risks of microgrid operation by reasonably scheduling flexible resources and reserving reserve capacity.
