With the high penetration of power electronic loads in grid, stability static synchronous compensator (STATCOM) devices is greatly challenged. However, conventional control methods for modular multilevel converter (MMC) based STATCOM only consider with small signal disturbances. This article proposes a novel dual-layer back-stepping (BSC) MMC-based STATCOM. In first layer, BSC aims to regulate ...

This paper presents a control scheme based on a static synchronous compensator (STATCOM) to achieve both voltage control and damping enhancement of a grid-connected integrated 80-MW offshore wind farm (OWF) and 40-MW marine-current farm (MCF). The performance of the studied OWF is simulated by an equivalent doubly-fed induction generator (DFIG) driven by an equivalent wind turbine (WT) while an...

Abstract: The use of the isolated hybrid power systems is being popular due to the continuous increasing gap between demand and supply of conventional energy sources and intermittent nature of non-conventional energy sources. Normally, the non-conventional energy source such as wind have induction generator to generate electricity but induction generators require reactive power for its operatio...

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...

In this paper, dynamic performance of a transformerless cascaded PWM static synchronous shunt compensator (STATCOM) based on a novel control scheme is investigated for bus voltage regulation in a 6.6kV distribution system. The transformerless STATCOM consists of a thirteen-level cascaded H-bridge inverter, in which each voltage source H-bridge inverter should be equipped with a floating and iso...
