Wang Xian · Power System Protection and Control · 2010
Interruptible load dispatch problem with multi-period and multi-interruptible-load is usually a multi-objective combinatorial optimization problem.First ,a multi-period and multi-objective interruptible load dispatch model is proposed ,in which several objectives ,such as minimizing the interruption payments and interruption frequency, can be included.The characteristics of different interruptible loads and the time period coupled constraints are also considered.Second, a solution method using discrete binary particle swarm optimization (BPSO) is developed for the multi-period and multi-objective interruptible load dispatch model.Numerical simulation for an interruptible load dispatch problem with 19 interruptible customers and 16 time periods demonstrates the effectiveness of the method.Comparisons between the simulation results produced by the BPSO and the genetic algorithm (GA) show that the BPSO can obtain better solutions than that of the GA.
