基于NSDE算法的船舶电力系统经济环境调度

由于船舶航行易受天气等因素的影响,具有不确定性和波动性的特点。本文深入研究了船舶航行和发电调度联合的电力系统优化调度问题,建立了非支配排序差分算法(NSDE)的船舶电力系统经济环境调度模型,在该模型中综合考虑发电成本和污染气体排放量,实现多目标优化。在约束条件中加入了船舶航行的约束,从而减小了速度变动对系统的影响。用NSDE完成简单快速的全局寻优,得到准确而完整的Pareto前沿,使所有目标函数尽可能达到最优。

Fault reconfiguration of shipboard power system based on triple quantum differential evolution algorithm

Fault reconfiguration of shipboard power system is viewed as a typical nonlinear and multi-objective combinatorial optimization problem. A comprehensive reconfiguration model is presented in this paper, in which the restored loads, switch frequency and generator efficiency are taken into account. In this model, analytic hierarchy process(AHP) is proposed to determine the coefficients of these objective functions. Meanwhile, a quantum differential evolution algorithm with triple quantum bit code is proposed. This algorithm aiming at the characteristics of shipboard power system is different from the normal quantum bit representation. The individual polymorphic expression is realized, and the convergence performance can be further enhanced in combination with the global parallel search capacity of differential evolution algorithm and the superposition properties of quantum theory. The local optimum can be avoided by dynamic rotation gate. The validity of algorithm and model is verified by the simulation examples.
