Abstract

This paper presents the development of a mathematical model representation of variable series capacitors which are also known as flexible AC transmission systems (FACTS) in power system economic dispatch. The objective of this research is to find the optimal locations of FACTS devices for improved economic dispatch. The proposed approach is based on the decomposition-coordination method and the network compensation technique. Taking the advantages of accumulated experience in power system optimization and the existence of the optimal power flow (OFF) software, the software development cost for implementing the proposed algorithm is reduced. In this paper, digital simulation studies on small power systems with and without variable series capacitors were conducted respectively. The purpose of these simulation studies is to assess the effectiveness of the proposed algorithm in minimizing the operating cost and enhancing the system performance. The results of the simulation studies and the proposed algorithm are presented and discussed in greater detail.

改进电力系统经济调度的变串联电容器最优补偿

本文提出了电力系统经济调度中可变串联电容器(又称柔性交流输电系统)的数学模型。本研究的目的是为了改善经济调度，找到FACTS设备的最佳位置。该方法基于分解协调法和网络补偿技术。利用在电力系统优化方面积累的经验和最优潮流(OFF)软件的存在，降低了实现该算法的软件开发成本。本文分别对具有可变串联电容和不具有可变串联电容的小型电力系统进行了数字仿真研究。这些仿真研究的目的是评估所提出的算法在最小化运行成本和提高系统性能方面的有效性。本文给出了仿真研究的结果，并对所提出的算法进行了详细的讨论。
