Abstract

Abstract: The application of the flexible DC loop network controller can be used to solve the problems that the tradition distribution network cant continue to run under the looped operation and improve the reliability of power supply. This paper establishes the location model based on the ‘primary screen-fine screen’ mode by means of decoupling the locating and sizing issues in order to solve the locating and sizing NP-hard problems of the flexible DC loop network controller. The model is central with power supply reliability with taking into account of the supply capacity and economic and realizes comprehensive optimization for assessment program through entropy and ideal point analysis manner. Then, this paper establishes the sizing model based on net load and feeder capacity, which carries out the life cycle management of assets concept. And three kinds of applicable sizing methods applied in different stages of development grid are studied based on the analysis of different stages of development characteristics of the grid, which has strong applicability. The scientific and engineering practicality of this model is showed through the analysis of a demonstration area.

Key words: MV distribution network, flexible DC loop network controller, primary screen-fine screen, locating and sizing
