Abstract

This application discloses a decentralized self-discipline optimization method for multiple virtual power plants, including: S1, parameter initialization; S2, task classification and formation of an initial knowledge matrix; S3, information acquisition; S4, determination of optimal individual actions; S5, calculation of each agent S6, calculating the reward function; S7, updating the knowledge matrix; S8, information feedback: each agent returns the current optimal solution to the information center; S9, judging whether the maximum number of iterations is reached, and if so, output The optimal knowledge matrix for the corresponding task; otherwise, return to S3. This application discloses a distributed self-discipline optimization method for multi-virtual power plants, which solves the problem that the existing distribution network regulation is difficult to meet the real-time participation of multiple virtual power plants in the power market for profit, and effectively control the grid-connected behavior of distributed equipment to support the distribution network. Technical aspects of safe and efficient operation.

Description

technical field [0001] The present application relates to the technical field of distribution network scheduling, 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, the impact of 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 equipment separately, and the impact of a single device on the power grid is very small. Direct control of a single device makes little sense. And the construction of the electricity market is progressing in an orderly manner. Due to the characteristics of smal...
