Study On The Evaluation And Optimization Method Of Power Emergency Plan Based On The Characteristics Of New Power Grid

The electric power emergency plan is the standard disposal process for power grid to deal with sudden accidents and disasters.Therefore,the quality of the plan is directly related to the timeliness of emergency disposal and the effectiveness of disposal results.However,the existing electric power emergency plans are all based on static conditions,which are often not practical in dealing with actual power grid accidents.Therefore,it is urgent to build a reasonable evaluation method for electric power emergency plans Method,used to evaluate the effectiveness of its implementation.The evaluation method for the effectiveness of the plan established in the second chapter of this paper is used to test the advantages and disadvantages of the existing plan,and can be used for the comparison between the same type of electric power emergency plans.The evaluation results can objectively and directly show the shortcomings of the existing plan through quantitative indicators,which has strong practicability.As the rule of emergency response,the plan needs corresponding verification means to test the effectiveness,integrity and feasibility of its actual operation.As the verification means of the plan,the electric power emergency drill also needs corresponding evaluation model.In Chapter 3,based on the traditional scoring system evaluation method,an evaluation method of the plan drill based on EMD method is established Expert evaluation language scale set,in a more reasonable way to evaluate the power emergency plan drilling process.In response to the concept of ubiquitous power Internet of things proposed by State Grid Corporation of China at the beginning of 2019 and the strategic development goal of "three types and two networks",Chapter IV of this paper proposes the concept of intelligent power emergency plan,and introduces the formulation criteria of emergency plan with line vulnerability as emergency prevention and emergency response,and also conceptually proposes the communication guarantee in intelligent power emergency plan Finally,it analyzes the information interaction evaluation method of intelligent power emergency plan under the ubiquitous power Internet of things,which can be used as an improved method to develop intelligent plan.Under the background of the development strategy of "three types and two networks",considering that many factors restrict each other and lead to grid accidents,it is very important to optimize the power emergency plan with the characteristics of flexible grid.The fifth chapter of this paper starts with the definition of the flexible power grid,through the extraction and analysis of the characteristics of the flexible power grid,the optimization method of the power emergency plan with the characteristics of the flexible power grid is disassembled into the optimization model based on the elastic index in the time dimension,the optimization model based on the scheduling coefficient in the object dimension and the network security edge in the communication dimension according to the principle of constructing the different scenarios Boundary optimization model.
