Usually a STATCOM is installed to support power system networks that have a poor power factor and often poor voltage regulation. It is based on a power electronics voltagesource converter. Various PWM techniques make selective harmonic elimination possible, which effectively control the harmonic content of voltage source converters. The distribution systems have to supply unbalanced nonlinear l...

Due to uncertain photovoltaic (PV) power generation, analyzing the voltage stability of transmission networks with a large PV plant is challenging. The output critical factor in establishing penetration levels active when assessing loading capabilities. Therefore, this article contributes enhancing understanding how static synchronous compensator (STATCOM) could be used as part system network. ...

This research article proposes a powerful fractional-order PI controller to mitigate the subsynchronous oscillations in turbine-generator shaft due to subsynchronous resonance (SSR) with flexible AC transmission system devices such as static synchronous compensator (STATCOM) and unified power flow controller (UPFC). The diminution of SSR is achieved by the raising of network damping at those fr...

The generation of power is really a challenge now a days with the increase in demand for Electricity due to increase in industrialization. It is necessary to meet the energy needs by utilizing the renewable energy resources like wind, biomass, hydro co-generation, etc. Injection of the wind power into an electric grid affects the power quality. The main power quality issues are voltage sag, swe...

Urbanization is continuing around the world accompanied by a constantly growing demand for energy. For these reasons, new and efficient solutions for power transmission are required. To cope with these new challenges a novel SVC PLUS (Static Var Compensation SVC) for Reactive Power Compensation is designed and researched. SVC PLUS is an advanced STATCOM (Static Synchronous Compensator) with Mod...

The system stability is greatly hampered when green electricity is feed into the conventional electricity network due to intermittent nature of renewable sources. The electricity generation from wind so far predominates than that of other renewable sources. In order to maintain system stability of the electricity network, IEC-61400 (International Electro-technical Commission) standard has defin...

The quality of the power supply in any industrial environment can have a dramatic effect on the cost of production. This is particularly true in a mining environment, both above ground and underground, because of the remote location of many mining sites. This paper considers various power quality issues and their effects, and then proposes the H-bridge multilevel static compensator (STATCOM) co...

This paper presents the stability-improvement results of a synchronous generator (SG)-based one-machine infinite-bus (OMIB) system with a hybrid doubly-fed induction generator (DFIG)-based and permanent-magnet synchronous generator (PMSG)-based offshore wind farm (OWF) using a static synchronous compensator (STATCOM). The operating performance of the studied PMSG-based OWF is simulated by an eq...

This paper aims to explore a viable solution for a doubly-fed induction generator (DFIG)-based wind farm to meet the reactive support requirement of the low voltage ride-through (LVRT) grid code with safe grid-connected operation during asymmetrical grid faults. First, the control scheme for the DFIG-based wind energy conversion system (WECS) is designed. Then, the controllability issue is anal...

This paper presents the DC voltage control design of D-STATCOM when the D-STATCOM is used for load voltage regulation. Although, the DC voltage can be controlled by active current of the D-STATCOM, reactive current still affects the DC voltage. To eliminate this effect, the control strategy with elimination effect of the reactive current is proposed and the results of the control with and witho...
