In order to ensure the efficient and reliable operation of the virtual power grid microgrid,a virtual power plant microgrid source load collaborative optimization scheduling model is constructed.On the basis of the normal distribution probability model,establish photovoltaic,wind turbine probability models,and load probability models,and based on this,carry out the scene construction of virtual power plant microgrids.Taking operational costs,renewable energy consumption,and environmental costs as optimization objectives,a source load collaborative optimization scheduling model is established.The optimal solution of the scheduling model is solved through the firefly optimization algorithm,in order to achieve virtual power plant microgrid source load collaborative optimization scheduling.The experimental results show that the wind power and photovoltaic output prediction accuracy of the constructed model is high,the abandoned wind power is low,the wind power utilization rate is high,and it has good collaborative optimization scheduling ability.
