Study On Substation Locating, Sizing And Coordination Optimization Of High Voltage Distribution Network Planning

In the power market, supply company attachs moreimportance to power systemplanning. There are many methods for power system planning, and each method hasits own advantage, disadvantage and applicable scope. According to systemengineering, power system planning are divided into substation locating,sizing andgrid optimizing,which are fulfilled successively.. On the basis of introducing themethods and basic knowledge of power system planning, this paper mainly studiescoordination planning and decision of substation of high voltage distribution network.According to the process of power system planning, the paper studies the optimizationof substation from three parts, including the analysis of electric power and energyequilibrium of high voltage distribution network, the study on two-phase optimizationplanning approach to substation locating and sizing, the discussion of coordinationplanning of multi-voltage substation. Each chapter cites or sets up applicable mathsmodels, especially, the second section gains the best scheme by using the advancedPSO algorithm, which can improve the applicability and level of power systemplanning, and make the substation planning of high voltage distribution networkbetter.In addition, each section gives numeral example to prove the availability of themodels and the planning methods.
