摘要
基于模块组合多电平换流器MMC的新型高压直流HVDC输电具有广阔的应用前景。针对传统控制器优化方法的不足,提出了一种基于差分进化膜计算的MMC-HVDC控制参数优化方法。基于MMC-HVDC的控制原理,在PSCAD下搭建了MMC-HVDC的仿真模型,利用差分进化膜计算优化控制系统参数。算例分析表明:该控制器能有效改善系统受到短路故障扰动后的动态特性;通过比较原参数、基于差分进化算法的优化结果和基于自适应差分进化算法的优化结果,验证了该方法的有效性。
High voltage direct current （HVDC）transmission based on modular multilevel converter （MMC） has a bright prospect in applications. Aiming at the shortcomings of the traditional optimization methods for controllers, an optimization method for the control parameters is proposed based on differential evolution membrane computing （DEMC）. A simulation model is established on PSCAD platform according to the control principle of MMC-HVDC, and the control parameters are optimized by using DEMC. The simulation analysis indicates that the proposed controller can improve the system＇ s dynamic characteristics when it is disturbed by short-circuit fault. From the comparison among the original parameters, the optimization results based on differential evolution algorithm, as well as the results based on adaptive differential evolution algorithm, the proposed method is proved to be effective.
