Virtual power plant multi-target economic dispatching method and system considering efficiency

The invention discloses a virtual power plant multi-target economic dispatching method and system considering efficiency, and the method comprises the steps: constructing a probability density function according to the historical wind and light output data of a virtual power plant, generating a wind and light output scene set through Monte Carlo simulation, reducing the scene through employing a Kantorovich distance method, obtaining a typical scene probability, and obtaining a wind and light output scene set; determining constraint conditions which need to be met when the virtual power plant aggregates distributed energy and dispatches, constructing a virtual power plant multi-target economic dispatch model with objective functions of energy utilization efficiency maximization and operation cost minimization, and solving the constructed virtual power plant multi-target economic dispatch model by using a mantis search algorithm. And a distributed energy output plan with the highest efficiency and economy in t
