facts technology has considerable applications in power systems, such as; improving the steady stateperformance, damping the power system oscillations, controlling the power flow, and etc. statcom is oneof the most important facts devices used in the parallel compensation, enhancing transient stability andetc. since three phase fault is widespread in power systems, in this paper statcom is used...

A hybrid-STATCOM in three-phase power system is proposed and discussed as a costeffective reactive power compensator for medium voltage level application is proposed in this paper. Because of these prominent characteristics, the system costs can be greatly reduced. Its V-I characteristic is then analyzed, discussed, and compared with traditional STATCOM and capacitive-coupled STATCOM (C-STATCOM...

This paper presents an advanced dynamic voltage restorer with integrated energy optimal compensation (EOC-DVR), which combines the advantages of pre-sag and minimization compensation. The performance parameters EOC-DVR, such as compensatory capability, loss energy, duration compensation, can be balanced by this strategy. Additionally, impact on load is further reduced proposed method. By analyz...

The paper presents considerations regarding to design and simulation of two adaptive controllers (self-tuning controller with feedback and respectively reference compensation) with application to a power system. The self-tuning control strategy is applied for the excitation control of a synchronous generator. There are analyzed the performances of the both considered self-tuning control structu...

We consider the problem of exploiting the microgenerators connected to the low voltage or medium voltage grid in order to provide distributed reactive power compensation in the power distribution network, solving the optimal reactive power flow problem for the minimization of power distribution losses subject to voltage constraints. The proposed strategy requires that all the intelligent agents...

This paper proposes a nonlinear control strategy of a Static Synchronous Compensator (STATCOM) for improving transient stability of multimachine power system. The large scale and the complexity of modern power system require the nonlinear control strategy of the STATCOM. The concept of Lyapunov energy function is applied to derive the nonlinear control strategy and the proposed control based on...

The Generalized Unified Power Flow Controller (GUPFC) is a Voltage Source Converter (VSC) based Flexible AC Transmission System (FACTS) controller for shunt and series compensation among the multiline transmission systems of a substation. The paper proposes a full model comprising of 60pulse Gate Turn-Off thyristor VSC that is constructed becomes the GUPFC in digital simulation system and inves...

In recent decades, the utilization of highly automatic electric equipments has resulted in enormous economic loss. Thus, the power suppliers as well as the power consumers are very much concerned about the power quality issues and compensation approaches. In order to deal with this issue, Active Power Filter (APF) has been considered as an attractive solution due to its significant harmonic com...

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...
