The load on the power system is always varying with respect to time which results in the variation of frequency, thus leading to load frequency control problem (LFC). The variation in the frequency is highly undesirable and maximum acceptable variation in the frequency is ± 0.5Hz. In this paper load frequency control is done by PI controller, which is a conventional controller. This type of controller...
An attempt is made to examine the effective application of artificial bee colony algorithm to optimize the parameters in load frequency control (LFC) of a two area interconnected thermal system. The proportional gains (Kp) and integral gains (Ki) have been optimized to ensure best performance of the system, minimizing the tie-line deviation and frequency deviations of both the areas. The settling...
In recent years, power systems have steadily grown larger and more complicated. Meanwhile, there has been a push toward a strong deregulation of the power industry, which has also progressed, causing increases in newcomers called PPS (Power Producers and Suppliers) generation ratio and power wheeling via the tie-lines connecting different power companies. These factors all contribute to the increase...
Purchasing and importing electricity from neighbor countries (or systems), has several benefits such as reduced network losses, reduced energy not served (ENS) criteria, possibility to export power to other systems, and probably the most important one is its contribution to supplying the load without increasing generation capacity. To improve reliability of the network by interconnecting systems,...
