Embodiment Construction

[0079] 1. Technical scheme of the present invention.

[0080] The intelligent distribution network panoramic fault recovery game method containing distributed power sources according to the present invention, the steps are as follows:

[0081] 1) Enter initial parameters

[0082] Input parameters such as the location of the fault, fault repair time, etc., and set the relevant initial parameters of the quantum particle swarm algorithm;

[0083] 2) Establish a game model

[0084] The establishment of the game model mainly includes four aspects: the player's strategy, the player's income, the player's constraint and the game mode.

[0085] 2.1) Player's strategy

[0086] Considering that the troubleshooting time is T hours, the set of all players is Γ={G i |i=1, 2, ..., T}. The set contains T players, and the player G i Respectively correspond to the distribution network under the fault recovery strategy of the i-th hour of the fault maintenance time. When the system fails...

Abstract

The invention discloses a novel full-view fault recovery game method which comprises the following steps of 1) inputting an initial parameter, 2) establishing a game model, 3) generating an initial game strategy space, 4) computing a local optimal strategy of a gamer i, 5) computing a local optimal strategy space, 6) performing convergence inspection, and 7) outputting a result. The method achieves fault recovery of an intelligent power distribution network comprising a dynamic load and a microsource parameter by introducing a theory of a game theory.

Description

technical field [0001] The invention relates to a panoramic fault restoration game method of an intelligent distribution network including distributed power sources, and is particularly aimed at the fault recovery problem of a distribution network under multiple fault maintenance times. Background technique [0002] In response to global climate change and energy structure adjustment, smart grid has become the common choice of the global power industry in the future. The smart distribution network aims to improve the user's power consumption efficiency, power quality and power supply reliability, which not only reduces the risk of large-scale user power outages, but also enables the effective use of distributed energy. At present, the main research directions include distribution network operation reliability, network structure optimization, distributed energy access location optimization, fault protection technology, etc. Among them, the fault recovery technology of the di...
