Abstract

Assessment of Maximum Loadability (ML) in the transmission network simulated for single (N-1) and double (N-2) contingencies is discussed in the projected work. Static Var Compensator (SVC), Thyristor Controlled Series Capacitor (TCSC) and Unified Power Flow Controller (UPFC) are some of the Flexible AC Transmission System (FACTS) devices, which, when installed in the transmission system, helps to achieve reactive power compensation and thereby increase the system loadability. Priority indices like Contingency Severity Index (CSI) as well as Fast Voltage Stability Index (FVSI) are used to identify the optimal location and control settings of these devices. Consequently by reducing the Installation Cost (IC) of FACTS devices, the social and economical reimbursement is improved and also useful in managing the overloading of transmission lines. The proposed problem is simulated using MATLAB 7.0 and tested with the help of Western System Coordinating Council (WSCC) 9 bus system and optimized using Modified Differential Evolution (MDE) algorithm.

多类型FACTS设备在N-1和N-2突发事件中最大负载能力的增强及其MDE算法优化

本文讨论了单次(N-1)和双次(N-2)事故下输电网络最大负载性的评估问题。静态无功补偿器(SVC)、晶闸管控制串联电容器(TCSC)和统一潮流控制器(UPFC)是柔性交流输电系统(FACTS)中的一些器件，当安装在输电系统中时，有助于实现无功补偿，从而提高系统的负载性。优先级指数，如应急严重性指数(CSI)和快速电压稳定指数(FVSI)被用来确定这些设备的最佳位置和控制设置。因此，通过降低FACTS设备的安装成本(IC)，提高了社会和经济的补偿，也有助于管理输电线路的过载。利用MATLAB 7.0对所提出的问题进行了仿真，并借助西部系统协调委员会(WSCC) 9总线系统进行了测试，并采用改进差分进化(MDE)算法进行了优化。
