Abstract

The invention discloses an optimal control method and device for a power distribution network. The method comprises the following steps that: on the basis of the first parameter data of a target powerdistribution network, dividing a power distribution area corresponding to the target power distribution network; on the basis of the second parameter data of the target power distribution network, determining a regulation and control instruction corresponding to each preset area; and on the basis of the regulation and control instruction corresponding to each preset area, carrying out regulationprocessing on the decision variable of target equipment in the preset area. By use of the method, the problems of single control means, poor flexibility and low equipment resource use ratio of the power distribution grid in the prior art can be solved.

Description

technical field [0001] The present application relates to the field of distribution network regulation and control, and in particular, relates to an optimal control method and device for a distribution network. Background technique [0002] The massive access of controllable resources such as distributed power, demand-side flexible loads, and electric vehicles requires a more flexible optimal control strategy for the distribution network. [0003] The traditional distribution network control methods mainly use power generation to track load fluctuations to achieve power balance, use power generation control to adjust the system operating status, and suppress distributed power output fluctuations by configuring energy storage or increasing power capacity. The control method is relatively simple. It does not give full play to the role of controllable resources such as flexible loads in the distribution network, lacks flexibility and diversity, and is difficult to meet the cont...
