With the widespread use of harmonic generating devices, the control of harmonic currents to maintain a high level of power quality is becoming increasingly important. An effective way for harmonic suppression is the harmonic compensation by using active power filter. This paper presents a comprehensive...
It proposes an improved controller that devotes itself not only to satisfying the requirement of dynamic reactive power compensation but also to achieving the balance of DC capacitor voltage. The new configuration is prominent in having no restriction on the number of power module. Simulation results...
Voltage-sourced converter circuits using gate turn-off (GTO) thyristors have been proposed as an alternative means of providing static VAr compensation (SVC). Such 'advanced SVCs' are classified under the nomenclature STATCOM (STATic COMpensator). The published converter circuits suitable for power sy...
A transmission line needs controllable compensation for power flow control and voltage regulation. This can be achieved by FACTS controllers. Static Synchronous Series Compensator (SSSC) is a series connected FACTS controller, which is capable of providing reactive power compensation to a power system....
SVC is a static var generator or absorber whose output is adjusted to exchange capacitive or inductive current to maintain or control specific parameters of the electrical power system (typically bus voltage). Its also can be used to control the V AR compensation, damping oscillations, t...
power flow various compensation methods like using FACTS controller are used in power system. In this paper the effect of Static Synchronous Series Compensator (SSSC) is presented. The dynamic performance of SSSC is presented by real time waveforms using MATLAB software for IEEE 4 bus system. ...
In this paper an attempt has been made to point out the basic differences between an `impedance based' controllable series compensation (CSC) and a static synchronous series compensator (SSSC), which is based on power electronic converters with GTO thyristors. First, basic theoretical considerations...
The traditional static idle work compensation system has many shortcomings,but the adoption of newest highly general static synchronous compensator (SSC) can satisfy the new electric power market requirements. SSC is a kind of parallel idle work compensation system. It can send out or absorb the re...

Within the new strategy, the photovoltaic array can generate relevant active power according to the depth of the grid voltage dip to keep power balance between the two sides of the photovoltaic inverter. A feed-forward compensation reflecting the instantaneous current injecting into the direct current...
