Scheduling Optimization Model For Electric Power Emergency Considering Multistage

In recent years,natural disaster factor and non-natural disaster factor happened frequently,which has increased the probability of occurrence of power accident disaster,and has put forward higher requirements for emergency treatment of electrical power system.The electric power emergency management can effectively delay the accident spread speed and reduce the accident disaster intensity.Based on electric power emergency stage theory,this text specifically expounds electric power emergency theory from four phases: power emergency mitigation phase,power emergency ready phase,power emergency response phase and power emergency recovery phase.And according to the specific work,electric power emergency can also be subdivided into power emergency risk management,power emergency location problem of the point that can be rescued,power emergency transit point optimization selection,power emergency optimal path selection,emergency response priority and power emergency multi-type material dispatching,as follows:First,the mitigation phase of power emergency mainly expounded the theory of power emergency risk management;risk identification and risk assessment is the core of risk management.Risk identification is the basis and support of risk assessment.Risk assessment is the purpose of risk identification and quantitative means.In this paper,risk identification theory,risk identification method and risk factor analysis are introduced.Based on the risk identification,the risk assessment theory is described from the risk assessment process and the assessment method.Finally,with the "mitigating" risk intensity model,analyzing the case of risk management case,quantifying the risk identification,assessment for reducing the risk of loss and delaying the spread of the role of risk.Secondly,in the ready phase of electric power emergency,the problems of retrieval depot selection and transit point optimization were focus on research.Based on the location of the disaster-prone point in electric power planning,this paper builds the emergency retrieval depot selection model and selects the site.Considering timeliness and economy,this paper introduces transit point of emergency materials and builds transit point site optimization model after defining retrieval depot and disaster-prone point,optimizes alternatives and defines optimal location.At the same time,this phase also elaborates how to manage power emergency supplies,human resources and environmental factor.Thirdly,the phase of power emergency response and the phase of power emergency recovery are discussed.The determination of power emergency response priority factor,optimal path selection problem of each node and optimization of multiple types of power emergency materials dispatching are mainly involved in the phase of power emergency response.Electric power emergency recovery requirements,power emergency recovery phase division,and supporting measures of power emergency recovery phase etc.are mainly involved in the phase of power emergency recovery.The electric power emergency involving the various stages of the theory has been comprehensively addressed in this paper.Finally,Emergency material supply point model,transit point optimization selection model,power emergency response priority model,node optimal path selection model,and multi-variety electric power emergency optimization model,etc.which are involved in the four-stage theoretical discourse,are given and used in this paper through cases assumption.The multi-species power emergency supplies scheduling optimization program is proposed,it can fully meet the supply and demand node power emergency material constraints.
