This paper presents the design of secondary voltage control by tuning the parameters of coordinated PID controllers to eliminate voltage violations in power system contingencies. The coordinated PID control parameters are tuned by using genetic algorithm. The study is presented on modified IEEE 14 bus system. The coordinated secondary voltage control is assigned to the generators and STATCOMs in order...
The paper presents dynamic assessment of voltage and reactive power control in the Main Interconnected Transmission System (MITS) in Oman. Two case studies are considered; namely the MITS with and without temporary diesel generators. Voltage and reactive power control is achieved by optimization process to maximize reactive power margin of generating units to maintain as much as possible reserves...
In this paper, gateway placement approaches in Wireless Mesh Network are studied and evaluated. Their purposes are classified. According to the relevant researches in this area, there are many gateway placement approaches in Wireless Mesh Network that have been found. These approaches are designed to find an optimal network throughput, cost minimization, quality of services and load balancing. In...
Using of mobiles and wireless devices becomes very important in recent years, due to the increase of services and applications they provide. The major issue is to provide seamless mobility to achieve better performance. The Internet Engineering Task Force has developed Mobile IP which allows Mobile node moving from a network to another using its original IP address. The Internet Engineering Task Force...
