Optimal configuration method and device for disaster prevention and emergency power supplies in urban area

Abstract

The invention discloses an optimal configuration method and device for disaster prevention and emergency power supplies in an urban area. The implementation of the method comprises the steps of calculating the outage loss of each important power user during a blackout period according to the determined deployment time from each subarea power supply station to each user, respectively calculating the emergency cost of a power company for deploying disaster prevention and emergency power supply vehicles for the users, describing the uncertainty of the disaster prevention and emergency power supply vehicle deployment time and the power user load respectively by a radial interval number and a general interval number, calculating the total social benefit, building a disaster prevention and emergency power supply optimal configuration model taking the maximum total social benefit as an objective function, and solving a best solution for deploying the disaster prevention and emergency power supplies for the important power users by the subarea power supply stations in the urban area through adopting a robust optimization method. The optimal configuration method is simple in calculation process, fully considers the uncertainty of the disaster prevention and emergency power supply vehicle deployment time and the uncertainty of the user load, meets dispatching requirements in the future to the maximum extent and weighs the outage loss and the emergency cost.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a method and device for optimal configuration of disaster prevention and emergency power sources in urban areas. Background technique [0002] There have been many large-scale power outages at home and abroad in recent years, such as the "11.10" blackout in Brazil in 2009, the "9.8" blackout in the United States and Mexico in 2011, and the Zhanjiang power grid in Guangdong in 2015. Although some scholars have proposed a variety of measures to prevent large-scale blackouts, it is impossible to completely avoid the occurrence of large-scale blackouts. Large power outages will bring huge economic losses, and may also cause serious social problems. Therefore, it is very important to establish effective and reliable emergency measures to deal with large-scale power outages. [0003] In order to improve the power system's ability to deal with emergencies and reduce the losses caused by l...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an emergency power supply for disaster prevention in urban areas in view of the complex calculation process of the prior art, the uncertainty of the deployment time of disaster prevention emergency power supply vehicles and the uncertainty of user load The optimal configuration method and device, the calculation process of the present invention is simple, and the uncertainty of the deployment time of the disaster prevention and emergency power supply vehicle and the uncertainty of the user load are fully considered, and the calculated optimal configuration scheme of the disaster prevention and emergency power supply can satisfy the greatest extent In the short term in the future, the demand for load growth of important power users in cities and the dispatching needs of emergency power supplies for disaster prevention during major power outages can also maximize the balance between power outage losses of important users and emergency costs of power companies
