Research On Investment Planning Strategy Of Distribution Network Planning Under The Condition Of Incremental Distribution Network Investment Business

With the continuous deepening of the new round of power system reform,the sales side introduced competition,and social capital participated in the investment of incremental power distribution business,which added uncertain factors to the investment of the power grid company.This paper first analyzes the development practice and experience of domestic and international power market,summarizes and analyzes the research progress of domestic and foreign distribution network investment planning strategies through literature literature,and provides empirical reference for subsequent modeling.Secondly,combined with incremental power distribution business The characteristics of the incremental power distribution business are put out under the different participation modes of the grid company.According to the progress of the reform,it can be divided into the first pilot and the whole network.According to the area where the incremental assets are located,it can be divided into blanks.The regional increment and the increment of all pilot areas;then,according to the reform process,analyze the possible impacts of future power market reforms on planning and investment.The impact on distribution network planning is mainly reflected in the three aspects of mechanism,resources and standards.The impact on investment distribution network is reflected in four aspects: investment scale,investment benefit,investment focus and investment risk.Finally,the strategy of investigating the grid enterprise is put forward in the incremental power distribution investment business.Distribution network benefit calculation model and investment risk assessment model under different participation modes,investment risk adoption Method to build the model,the investment risk to quantify the incremental distribution network,and finally the actual area for verification.
