LONG-RANGE PLANNING OF POWER DISTRIBUTION SYSTEMS: PRIMARY NETWORKS

This paper focuses on the expansion planning of power distribution systems. An optimization model that considers substation location and sizing, primary feeder routing and reconductoring simultaneously is used to design expansion plans. The model considers the fixed and variable costs for all new elements and also for the existing ones when expansion is taken into account. The objective function seeks to minimize the total annualized expansion cost that includes the cost of losses modeled as a quadratic function. An efficient implicit enumeration algorithm combined with several heuristic procedures allows to solve large expansion problems in very reasonable time using microcomputers. The radiality is obtained by applying heuristics that deal with the true expansion costs. The voltage drop constraints are checked in the final radial solution and corrective actions are performed if they are not satisfied. (A)
