In certain regions and countries, the static synchronous compensator (STATCOM) is required in large-scale wind farms to provide reactive power support. Due limitations complexity distributed systems, STATCOM considered as an effective cheap alternative for impedance shaping mitigate resonance. However, there still a lack of quantitative stability analysis practical optimization approach achieve...

In modern electrical distribution systems harmonic distortions are created from a number of sources such as variable frequency drives, lighting, computers and nonlinear loads. Such harmonic distortions produce a variety of undesirable side effects ranging from poor power factor, motor failure to overloading of transformers and conductors. Now a days increasing number of renewable energy systems...

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...

Today Transmission & Distribution network of power systems are very stressed due to growing demand of better quality of power at lower cost. As a result transmission networks are operating on high transmission levels. Transient stability, damping oscillations etc are the major operating problems that power engineers are confronting during transmitting power at high levels.Transient Stability in...

Here in this paper presents a control strategy based on a static synchronous compensator (STATCOM) obtain both voltage control and damping enhancement of grid connected integrated 80 MW offshore wind form (OWF) and 40 MW marine current farm (MCF). The demonstration of the investigated Offshore Wind Farm is simulated by an equivalent wind turbine (WT) while an equivalent squirrel cage rotor indu...

Damping of low frequency electromechanical oscillations is very important for a safe system operation. The fast acting, of a static synchronous compensator (STATCOM) which is capable of improving both steady state and dynamic performance permits newer approaches to system stabilization. This paper presents a novel methodology for tuning STATCOM based damping controller in order to enhance the d...

The main aim of this paper is to improve the transient stability Doubly Fed Induction Generator (DFIG) based wind turbine using Static Synchronous Compensator (STATCOM). In paper, a multi-objective problem formulated minimize voltage deviations at point common coupling (PCC) and mitigate low frequency oscillations after clearing faults. Genetic algorithm STATCOM controller used enhance grid-con...

Degradation of the dc-link capacitance due to aging, cell failure, and fuse failure has a negative impact on ac-side current THD distribution static compensator (D-STATCOM) power quality. These variations noticeably increase modulation index voltage ripple leading growing D-STATCOM. To solve this problem, article proposes modification mechanism as secondary control layer added common structure,...
