Abstract

The invention discloses a multi-virtual power plant decentralized self-discipline optimization method. The method comprises the following steps: S1, initializing parameters; S2, classifying tasks andforming an initial knowledge matrix; S3, acquiring information; S4, determining an optimization individual action; S5, calculating an objective function value of each agent; S6, calculating a rewardfunction; S7, updating the knowledge matrix; S8, information feedback: each agent returns the current optimal solution to an information center; and S9, judging whether the maximum number of iterations is reached or not, and if yes, outputting an optimal knowledge matrix of the corresponding task, otherwise, returning to S3. By applying the multi-virtual power plant decentralized self-discipline optimization method, the technical problems that the existing distribution network regulation and control cannot meet the requirement that a plurality of virtual power plants participate in the power market in real time for profit-by-profit, and the grid connection behavior of distributed equipment is effectively controlled to support the safe and effective operation of the distribution network aresolved.

Description

technical field [0001] The present application relates to the technical field of distribution network dispatching, in particular to a decentralized self-discipline optimization method for multiple virtual power plants. Background technique [0002] With the development of energy utilization technology, a large number of distributed power sources are connected to the distribution network, and the number of distributed energy storage systems and controllable loads is also increasing day by day. On the one hand, due to the huge number, its comprehensive effect on the power grid cannot be ignored; on the other hand, its huge number makes it impossible for the power grid to directly dispatch each distributed device individually, and at the same time, a single device has little impact on the power grid. Direct control of individual devices makes little sense. And the construction of electricity market is advancing in an orderly manner. Due to the characteristics of small capacit...
