A Multistage Value-Based Model for Prioritization of Distribution Projects Using a Multiobjective Genetic Algorithm

[摘要] This article addresses the project prioritization problem as a part of the distribution system planning process. The projects must be selected and scheduled in a multistage planning horizon, to fit the utility available budget. The proposed decision model is value based, and prioritizes the local projects in a systemic way. The value attributes consider the financial impacts, number of consumers and some aspects of the distribution system operational performance and power quality. An analytic model optimizes the project portfolios by means of the NSGA-II multiobjective genetic algorithm. The optimization obtains a set of Pareto-optimal solutions, which are the trade-off project portfolios, with respect to the problem objectives and constraints. The presented case studies indicate some changes in the choice of priority projects. The proposed project selection methodology helps in raising strategic investments and allows for better distribution system planning...
