The importance of preventing the voltage collapse is gaining importance due to increase in dependency on the use of electricity. This has compelled the utilities to maintain high system reliability. The evaluation of a power systems ability to withstand dangerous contingencies and to survive to a normal or acceptable operating point is a prerequisite for security analysis. Line outage often cau...

in this paper, the performance of two types of facts devices in order to enhance the power system static voltage stability has been investigated. these devices include static var compensator (svc) and thyristor controlled series capacitor (tcsc). the modeling of the single machine infinite bus (smib) and aforesaid devices has been made up in steady state mode with disregarding of the generator ...

Many of papers refers to study of application for FACTS. Especially for using reactive compensators for 500KV power system in order to increase the static voltage stability margin and transient stability enhancement have considered. However the selection of suitable Var source (STATCOM or SVC) also need to be considered. The purpose of this paper is to solve the above problems in order to sugge...

The maximum loading of the transmission lines depends upon various limits. These are related to the environmental conditions, length of the line and various stability related issues. The VAR plays important role in maximising the power transfer through a transmission line. The FACTS Controllers have a major part to play in the VAR Management, in order to increase the maximum loading capability....

in methods presented to calculate the voltage collapse point, the transmission system is usually the only part of the power system that is completely modeled. distribution systems are often replaced by aggregate load models because the use of the detailed model of distribution systems in voltage stability analysis not only increases the computation time, but also decreases the probability of co...

The paper investigates on the design aspects of different SRAM cells for access time, power consumption and static noise margin. All the designs are made by using standard 90nm CMOS process. Simulations have been done for 6T, 7T, 9T and 10T SRAM cells. 10T SRAM cell shows the best SNM among all the simulated cells. 9T shows least power and least access time. 6T cells stability limits the potent...

The explosive growth of battery operated devices has made low-power design a priority in recent years. Moreover, embedded SRAM units have become an important block in modern SoCs. The increasing number of transistor count in the SRAM units and the surging leakage current of the MOS transistors in the scaled technologies have made the SRAM unit a power hungry block from both dynamic and static p...

The requirement for minimized cost whilst preserving power system reliability necessitates the development of both efficient system security assessment approaches and appropriate emergency remedial actions. Load shedding is a type of corrective actions that is applied to save power system stability against severe disturbances. This paper proposes an optimal load shedding policy that takes into ...

Abstarct: This paper presents an algorithm for solving the multi-objective reactive power dispatch problem in a power system. Modal analysis of the system is used for static voltage stability assessment. Loss minimization and maximization of voltage stability margin are taken as the objectives. Generator terminal voltages, reactive power generation of the capacitor banks and tap changing transf...
