Genetic algorithm for optimal open-loop distribution network design in competitive pool

The paper presents the Computer Aided Design of Distribution Network (CADDiN) application based on geographic information system (GIS) and genetic algorithms designed to improve the planning of major investment in open-loop distribution network over the coming years. The system allows the planner to identify, from load forecast, data on the existing distribution system and all future projects, the projects to be undertaken together with the commissioning year, in such a way that the investment and maintenance costs, as well as cost of losses are minimized over a planning horizon. The application has been tested with real size distribution systems achieving optimal designs in reasonable CPU times compared with respect to the dimensions of such distribution systems.
