Two-stage power-system-distribution-planning algorithm

A two-stage power system distribution planning algorithm is developed for solving sizing, location and timing problems of distribution substations and primary feeders. This comprehensive algorithm involves an accurate small-area electric load forecasting procedure, and provides the flexibility for both static- and dynamic-planning application modes. Also, the algorithm includes a new nondiscrete planning model which accurately simulates the different cost functions of substations and primary feeders. Moreover, constraints on voltage drop, equipment capacity and power conservation constraints are included in the planning problem formulation. Finally, the proposed algorithm is illustrated using a detailed numerical example, and subsequently tested for both efficiency and accuracy
