Experience with optimization software for distribution system planning

This paper presents a computerized optimization tool used to improve the planning of major investments in the distribution system over the coming years. The system allows the planner to identify, from load forecasts, data on the existing distribution system and all future projects, the projects to be carried out, together with the commissioning year, in such a way that the investment and maintenance costs, as well as the cost of losses are minimized over the planning horizon. The system is based on a dynamic model of network planning solved by a heuristic method comprising five phases. At the present time, the two first phases are implemented and the software is used by Hydro-Quebec planners. Substantial savings on investment, maintenance and loss costs have already been realized.
