This paper demonstrates an enhancement of power quality in grid integrated systems with the help of the proposed control strategy for voltage source converter based active power filters. The Shunt Active Power filters (SAPF) are extensively utilized in modern grid integrated systems to diminish the power quality concerns associated with it. The SAPF is one of the various power filters, which ha...

345 Abstract—In this paper Static Synchronous Compensator (STATCOM) is used for voltage stability and the compensation of reactive power. The STATCOM contains an Insulated Gate Bipolar Transistor (IGBT) based voltage source converter for voltage control and reactive power compensation. The STATCOM is used to control the reactive power with the voltage source converter in combination with a DC v...

A new model of Interphase Power Controller (IPC) for controlling active power is introduced in this paper. In this model, which is called VSC-based IPC, the voltage source converter (VSC) does the function of the phase shifting transformer (PST) in IPC. This new structure not only has the features of IPC, but also controls the output power effectively when the input power is changed by alternat...

Three-phase voltage source converters (VSC) are commonly used to convert ac power from a three-phase grid to a regulated dc voltage with unity input power factor. The control of the VSC is normally achieved by an outer voltage feedback loop and a sinusoidal pulse-widthmodulated (SPWM) inner current loop. However, the nonideal power grid and the presence of other interacting loads give rise to n...

The voltage source converter (VSC) excitation system is a novel excitation system based on pulse-width modulation (PWM) voltage source converter, which is proposed as improved alternatives to the conventional thyristor excitation systems. This paper aims to provide theoretical confirmation of power system stability enhancement by the VSC excitation system. The reactive current injected to gener...

The Alternate Arm Converter (AAC) is a voltage source converter being developed as an alternative to the Modular Multilevel Converter (MMC) for HVDC power transmission and reactive power compensation. Each Arm of the converter contains high voltage series IGBT Director Switches and full-bridge cells, which enables the VSC to ride through AC and DC network faults. This paper describes how the AA...

This paper deals with the study of different type of MPPT (Maximum Power Point Tracking) algorithms in a solar photovoltaic system (SPV) in order to extract maximum power from the solar modules. Here the solar array is integrated with the grid to provide power, as the traditional sources of power generation is depleting at a faster rate and also to provide power during peak hours in urban areas...

This paper focuses on a new controller design for both AC output voltage and DC voltage sides of a 3-level voltage source converter (VSC) of STATCOM based on complex transfer function. With this approach, the current regulator control with two-input two-output for the AC side of VSC can be represented by a complex transfer function with single-input single-output. In addition, the complex pole-...
