Research on Non-convex Algorithm for Encapsulating and Unsealing of Integrated Energy System with Asynchronous Communication Distribution

In order to address the economic problem when there are equipment with non-convex cost functions in the collaborative dispatch of integrated energy systems, a method of encapsulating and unencapsulating non-convex functions is proposed on top of the collaborative optimization method using distributed asynchronous communication. The non-convex function of the cost function of the generation equipment in the multi-energy microgrid exists, and the non-convex interval of the non-convex function is encapsulated and unencapsulated when the price after operation overlaps with the price of the non-convex interval. The method can solve the problem that the cost function model of multiple equipment for multiple energy sources is a non-convex function. The paper also demonstrates the effectiveness of the overall algorithm in terms of theoretical proofs and simulation experiments.
