Abstract

The present invention is a dynamic planning method for power distribution automation terminal layout optimization considering power supply reliability and economic cost. Fault indicators, voltage time type terminals, and voltage and current type terminals are installed on overhead lines, and fault indicators, voltage and current type terminals are installed on cables. For the two-remote terminal and the three-remote terminal, determine the fault impact mode according to the type of automation terminal, divide the regional nodes of the distribution grid with the switch as the boundary, and use the annual average failure time of the user as the index to evaluate the reliability of the power supply. The dynamic programming model of distribution automation terminal layout optimization with fault outage time as the optimization goal and the total investment as the optimization goal is programmed using JAVA language, the distribution network data is read from the XML file, and the distribution network area is divided with the switch as the boundary The nodes use the open source graphics library JGraphT to store the topology information of the distribution network, and call the general algebraic modeling system GAMS to solve the optimization model of each stage. The chosen solver is BARON.
