The objective of the paper is the application of modular multilevel cascade converter based on double star bridge cells (DSBCs) to a Static synchronous Compensator (STATCOM), for reactive-power control. The power consumed by the heavy load will create an unsymmetrical current will reducing the quality of the power in the electrical grid. Due to the unsymmetrical current the electrical power in ...

The use of a super-capacitor as storage device integrated with Voltage source converter-based shunt-connected Static Synchronous Compensator (STATCOM) is proposed for improving the STATCOM performance during sudden large disturbances in power network. was applied across capacitor disturbance condition. MATLAB simulations were carried out verification secondary function like oscillation damping,...

The model predictive control (MPC) methods have been widely applied due to the fast dynamic performance and multiple targets. However, they show certain limits when multilevel converters, such as unfixed switching frequency, large computation burden, complex weighting factors selection. This article proposes a novel modulated MPC (M <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlin...

This paper presents the stability enhancement of four parallel-operated offshore Wind Turbine Generators (WTGs) is connected to an onshore power system using a Static Synchronous Compensator (STATCOM). The operating characteristics of each of the four WTGs are simulated by wind permanent magnet synchronous generator while the onshore power system is simulated by a Synchronous Generator (SG) fed...

Power systems are subjected to small–signal oscillations that can be caused by sudden change in the value of large loads. To avoid the dangers of these oscillations, the Power System Stabilizers (PSSs) are used. When the PSSs can not be effective enough, installation of the Thyristor–based compensators to increase the oscillations damping is a suitable method. In this paper, a Static Synchronou...
