This paper proposes the latest application of power tracing technique for voltage stability improvement. Instead of solving losses charge allocation problem in deregulated power market as performed by many researchers, the proposed technique can be implemented for effective static generation power dispatch; that is, by determining suitable generating units involved in re-dispatching with the ai...

In general, reactive power compensation for power factor and stability of the supply system can be improved. The STATCOM (STATic synchronous Compensator) is being increasingly popular in power system applications. A small signal model of the STATCOM has been proposed without controlling DC link voltage. This scheme controls the phase angle as well as modulation index of the switching pattern. W...

Voltage stability problems usually occur in heavily loaded systems. Nowadays the power demand increases enormously, hence in a large interconnected power system network subject to stress conditions. This situation can be handled by increasing the generation or reducing the transmission losses. When the load increases suddenly, voltage magnitude also varies beyond the permissible voltage stabili...

When power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. Therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. SSSC is a FACTS device con...

Voltage stability of a system is affected by reactive power limit of the system. FACTs devices improve the reactive power flow in system thereby improving voltage stability. This paper explores the effect of SVC and STATCOM on static voltage stability. IEEE14 bus system has been used to demonstrate the ability of SVC and STATCOM in improving the voltage stability margin. These FACTs controllers...

This paper proposes an efficient optimization approach to determine the optimal placement and size of Static VAR Compensator (SVC) in a hybrid power system. The hybrid power system consists of conventional thermal generators, wind farms and solar photovoltaic (PV) modules. In this paper, the optimal placement and size of SVC is determined by considering the voltage deviations minimizations and ...
