Power distribution decision modeling method based on relevance between transformation measures and load loss indexes

Abstract

The invention relates to the technical field of power systems, and provides a multi-year investment planning decision-making modeling technology based on relevance between power distribution network reconstruction measures and power grid load loss capacity indexes in order to solve the problem of complex load flow calculation involved in traditional power distribution network investment decision-making modeling and consider improvement of operation reliability indexes of a current power distribution network. According to the modeling technology, through the data mining technology, the investment decision model has great advantages in the aspects of finding problem potential rules, improving the calculation efficiency and the like, the complex load flow calculation process can be avoided, and the calculation efficiency is effectively improved. A training sample set is formed by load loss indexes and transformation measures, and corresponding association relationship rules can be obtained through offline learning of sample data and serve as the basis of a multi-year investment decision-making model. In practical application, when a reconstruction measure configuration scheme is given, the deep belief network model can quickly give a result of a load loss index as a constraint condition of a subsequent power distribution network investment decision model.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a power distribution decision modeling method based on the correlation between renovation measures and lost load indicators. Background technique [0002] The National Energy Administration issued the "Action Plan for Construction and Transformation of Distribution Networks (2015-2020)" in August 2015, which requires my country to accelerate the construction of modern distribution networks and further improve the reliability of power supply. Therefore, how to scientifically utilize the transformation funds and formulate a reasonable transformation plan is one of the key issues in the field of power distribution today. The fundamental task of distribution network is to provide users with safe, stable and high-quality power supply. Compared with the transmission network, it has many nodes and a complex structure, which has a greater impact on the reliability of power supply....
