Abstract

The invention belongs to the technical field of distributed energy optimization operation, and particularly discloses a regional energy system optimization method considering power distribution network planning, and the method comprises the steps: obtaining an optimal grid structure obtained by carrying out the optimal solution calculation of a first objective function with the minimum planning total cost as a target under the consideration of the constraint of a downlink optimal power solution; and based on the optimal grid structure, obtaining an optimal power solution obtained by optimizing a second objective function with maximum energy utilization efficiency and new energy consumption rate in the regional energy system as an objective under various energy contribution balance constraints, and transmitting the optimal power solution to the first objective function to participate in planning solution. The optimization operation of the RIES is considered in the power distribution network planning, and the power distribution network planning and the optimization operation of the RIES are subjected to interactive optimization, so that the problems that prediction errors are generated in the optimization process and the prediction errors are increased along with the increase of the time scale are effectively solved.

Description

technical field [0001] The application belongs to the technical field of distributed energy optimization operation, and specifically relates to a regional energy system optimization method considering distribution network planning. Background technique [0002] Most of the current optimal scheduling methods are open-loop optimal scheduling methods, that is, optimal scheduling control is performed at a certain time section or multiple time periods, which is still a static optimization. However, the net load forecast inevitably has certain errors, and the forecast error increases with the increase of the time scale. Contents of the invention [0003] This application provides a regional energy system optimization method considering distribution network planning, which is used to solve the problem that there is a certain error in the existing optimal dispatching method of the regional energy system, and the prediction error increases with the increase of the time scale.
