Problems solved by technology

[0006] Traditionally, power companies are more casual in prearranging power outages, usually randomly executing them according to the order in which the power outage plan is formulated, without considering the correlation between power outages and optimizing the resulting impact, which will cause large power outage loss

Abstract

A power outage plan optimization decision method aiming at reducing power outage time and quantity comprises the following steps: reading the topology information of a distribution network, and establishing the contact relationship between distribution network components in a region to be evaluated to form a contact matrix; reading the information of each load point in the distribution network; reading power outage event information; for each type of power outage events, reading the information of maintenance teams in the region to be evaluated (including the number BN of the maintenance teams in the region to be evaluated, the ability of the maintenance teams and the daily workload of the maintenance teams), and making clear the power outage strategy in the region to be evaluated; optimizing the power outage period; optimizing the power outage order; and displaying the result. The method takes the user's power outage time, the user satisfaction and the team's ability into full consideration, and adopts simultaneous maintenance. For different power outage events, the execution time of each power outage time is optimized based on the daily load curve of an affected region. Thus, the power outage time and power outage quantity of the system are reduced effectively, reliable power supply of the system is ensured, and the customer satisfaction is improved.

Description

technical field [0001] The invention relates to a power system evaluation method. In particular, it relates to an optimal decision-making method for power outage planning for planning power outage events in distribution networks with the goal of reducing power outage time and electricity. Background technique [0002] The power system consists of power generation, power transmission, power distribution and power consumption and other parts of the system. As the last link of power transmission to users, the power distribution system has the closest connection with users and the most direct impact on users. It is the key link to ensure the quality of power supply, improve the efficiency of power grid operation, and innovate user services. It is a critical stage in the supply and distribution of electrical energy. The operation of the power distribution system is directly related to whether users can use electricity normally and reliably. When these devices are out of service...
