| 摘 要： | 为了提高交直流互联系统的整体动态稳定性,提出了一种新的基于混沌优化思想的自适应混沌粒子群优化算法,并将其应用于多馈入直流输电系统中各直流调制的优化协调.该算法利用混沌运动的遍历性来初始化粒子群以增强群体的多样性,在粒子群的每次迭代更新计算中,按适应值大小选取部分粒子对其进行混沌优化以帮助惰性粒子跳出局部极值区域,根据每个粒子的适应值自适应地调整其惯性权重系数以提高整个群体的全局与局部搜索能力.以一三区域双馈入交直流并联输电系统为例,选取与直流线路并联运行的交流联络线上的有功功率偏差和各发电机的功角偏差构成目标函数,应用自适应混沌粒子群优化算法对各双侧频差直流调制控制器的参数进行了全局优化协调整定,并与传统粒子群优化算法、遗传算法的优化结果进行了比较,结果表明该算法能更好地实现各直流系统调制间的优化协调,增强了整个系统对低频振荡的阻尼能力,可作为多馈入直流输电系统中直流调制优化协调的一种有效方法.

| Abstract: | In order to enhance the dynamic stability of AC/DC power system,a novel adaptive chaos particle swarm optimization(ACPSO) algorithm is presented and applies to design optimal coordinated HVDC modulators for the multi-infeed HVDC system.According to the proposed ACPSO algorithm,the diversity of the particle swarm is enhanced by using the ergodicity of the chaos motion to initialize the swarm;a part of particles are chosen on the basis of their fitness value and optimized by chaos optimization algorithm to he... |
