The work presented in this article is a contribution to the problem of controlling reactive powers and voltages an electrical network. Among these control tools, static power compensator (SVC) was chosen because its simplicity control. SVC one Alternative Flexible Current Transmission Systems (FACTS) devices which help solve problems encountered operation networks, either on distribution side o...

Abstract—The global energy consumption is increasing persistently and need for distributed power generation through renewable energy is essential. To meet the power requirements for consumers without any voltage fluctuations and losses, modeling and design of multilevel inverter with Flexible AC Transmission System (FACTS) capability is presented. The presented inverter is provided with 13-leve...

This paper presents a nonlinear controller design for a DSTATCOM connected to a distribution network with distributed generation (DG) to regulate the line voltage by providing reactive power compensation. The controller is designed based on the partial feedback linearization which transforms the nonlinear system into a reduced-order linear system and an autonomous system whose dynamics are know...

This paper deals with the modeling and simulation of Distribution Static Compensator (D-STATCOM) for voltage sag mitigation. The D-STATCOM simulation model consists of 12-pulse inverter, which is connected in shunt with the system. A generalized sinusoidal pulse width modulation (SPWM) technique was developed in the proposed controller for fast control action of the D-STATCOM. Simulations of th...

This paper solely discusses the voltage instability with the increment of load in a radial distribution system with Distribution Generation(DG) and compared to the system with Facts. The active and reactive power support from DG makes the system more reliable to voltage collapse. FACTS are also very good in reactive power compensator for the “sagging” voltages during the voltage collapse. The f...

The change in system voltage and frequency with changing load creates problem in power system stability. For the sake of system stability and reliability, the reactive power compensation is essential for flexible AC transmission system (FACTS). The variation of reactive power causes impact on the generating units, lines, circuit breakers, transformers, relays and isolators. However the reactive...

The paper presents some considerations regarding the structure and behaviour of the static var compensator (SVC). Thus, starting from a structure of the compensator it determinates the fundamental impedance of the SVC and it analyses the dependence of the impedance v.s. the components elements (C, R, Lc). Also, it has been realised and the analyses regarding the overvoltages which can appears o...
