Power system optimization method and system based on multi-element load demand response excitation

Abstract

The invention provides a power system optimization method and system based on multi-element load demand response excitation, and belongs to the technical field of power system optimizing.According to the scheme, the randomness and uncertainty of user behaviors can be accurately quantified by describing user portraits of flexible resources on the user side in a power system, and the user experience is improved. On the basis of the obtained user portrait, the accuracy of power system optimization is effectively improved by combining a demand response mechanism based on a utility function, a weighted graph and a shortest path proposed by the scheme; secondly, the randomness and uncertainty of user behaviors in the power system are fully considered in the user portrait construction process, the representativeness of the user portraits is ensured by adopting the scheme of combining scene generation and scene reduction, the calculation complexity of subsequent optimization solution is reduced, and the user portrait construction efficiency is improved. And accurate and efficient user behavior description is provided for subsequent demand response mechanism design, so that the efficiency and accuracy of power system optimization are effectively improved.
