This paper proposes a novel multi-objective optimization algorithm: differential evolution inspired clone immune multi-objective optimization algorithm (DECIMO). The novel algorithm uses a space-filling experimental design named symmetric Latin hypercube design (SLHD) to initialize the population which can obviously improve the uniformity of the individual distribution. A permutation of population individual indexes is generated and then a neighborhood for each population individual is defined according to the permutation. A differential evolution inspired neighborhood recombination operator, which based on the neighbors of each population member, is proposed to balance the exploration and exploitation abilities of the algorithm with no compromise of efficiency. The DE inspired operator is then invoked into the clone immune algorithm (CIA) to solve multi-objective problems (MOPs). We compare the proposed algorithm with NSGA2 and SPEA2 by executing it to 5 famous test functions. The results show that the proposed algorithm can fast converge to the global Pareto front and also can sustain a very uniform distribution. It is a potential algorithm for solving MOPs.
提出了一种新的多目标优化算法:差分进化启发克隆免疫多目标优化算法(DECIMO)。该算法采用对称拉丁超立方体设计(symmetric Latin hypercube design, SLHD)的空间填充实验设计来初始化种群,可以明显提高个体分布的均匀性。生成种群个体指标的排列,并根据该排列定义每个种群个体的邻域。为了在不影响效率的前提下平衡算法的探索和利用能力,提出了一种基于每个种群成员邻居的差分进化启发的邻域重组算子。然后将该算子引入克隆免疫算法求解多目标问题(MOPs)。通过对5个著名的测试函数执行,将该算法与NSGA2和SPEA2进行了比较。结果表明,该算法能快速收敛到全局Pareto前沿,并能保持非常均匀的分布。它是求解MOPs的一种很有潜力的算法。

The main objective of reheating furnace is to heat billets up to uniform temperature so as to result in successful rolling process. Since furnace temperature is key point for controlling billet heating, in this paper, a cubic spline is adopted to fitting furnace temperature distribution. Furthermore, a strategy of weighted slide window dynamic compensation and an optimal searching method of eccentric dynamic immune clone algorithm are presented to optimize set point of furnace temperature. Simulations show the effectiveness and efficiency of the proposed strategies.

With the increase of wind generation penetration in power systems, it becomes more and more important to study its impact on power systems characteristics. The accurate dynamic modeling of wind plants is critical for the grid planning and operating studies. The field test of a three phase short circuit fault at a 35kV busbar in a wind farm in Zhangjiakou Area was performed and a series of corresponding measurements were carried out. A variable speed doubly fed induction generator (DFIG) model in Power System Analysis Software Package (PSASP) is validated and parameters in the models are adjusted by comparing with the results from the field test. Based on the well adjusted parameters of the DFIG model, simulation result shows a better agreement with the field test, and the model has been verified. The reasons for the mismatch between the simulation and the field test results have also been analyzed in the paper. The study contributes to analyzing the impact of grid-connected DFIG on transient stability of the power system.

In this paper, a two-enterprise symbiosis Lotka--Volterra system with continuous delay is considered. We first introduce the characteristic of enterprise system, and then investigate the stability of the positive equilibrium and the existence of Hopf bifurcations. The direction and the stability criteria of the bifurcating periodic solutions are obtained by the normal form theory and the center manifold theorem.
