Research on the Coordinated Scheduling Method of Distribution Network Considering Flexible Loads

With the increasing proportion of flexible loads in distribution networks, this paper establishes the dispatching models of electric vehicles, energy storage, electric boilers and incentive loads in distribution network dispatching; establishes the optimization objective and constraints of distribution network coordinated dispatching that comprehensively considers the suppression of new energy access, peak shaving and valley filling, and the safe and economic operation of distribution networks; studies the solution strategies for the above large-scale complex dynamic programming problems, and proposes a distribution network coordinated dispatching method considering flexible loads; Taking the power grid of Dalian, Liaoning Province, China as an example, an application analysis was conducted.
