The fast and coordinated voltage control of distributed nodes inside a large scale wind farm is a stringent issue. To achieve the reactive power compensation without a dedicated upper communication system, this paper proposes a relative control strategy based on the local reactive power regulation. This method can realize the voltage coordination of the key equipment and feeder line nodes, on t...

This paper incorporates Corrected Transient Energy Margin (CTEM) to the clearing of coupled energy and reactive power market in the form of multi objective framework which includes two objective functions. The first one is the minimization of offer cost of generators for their active power generation in energy market plus Total Payment Function (TPF) of generators for reactive power compensatio...

A novel market design is proposed and developed that uses the energy-balance services for transmission-congestion relief. In this proposed market, all generators and customers have the ability to submit their offers to increase/decrease their generation/consumption, respectively. Each participant provides a ‘price–quantity’ offer to the independent system operator (ISO) which is independent of ...

This paper presents the particle swarm optimization (PSO) for reactive power and voltage control (Volt/Var Control) in distribution system considering DFIG wind farm. In this paper, the reactive power output of DFIG wind farm has been considered as the control variables in the Volt/Var Control scheme by considering the reactive power compensation capability of DFIG. The minimization of total sy...

In this paper, the concept of secondary control is applied for voltage unbalance compensation in an islanded microgrid. The aim of the proposed control approach is to enhance the voltage quality at the point of common coupling (PCC). Unbalance compensation is achieved by proper control of distributed generators (DGs). The DGs control structure mainly consists of active and reactive power contro...

The Generalized Unified Power Flow Controller (GUPFC) is a Voltage Source Converter (VSC) based Flexible AC Transmission System (FACTS) controller for shunt and series compensation among the multiline transmission systems of a substation. The paper proposes a full model comprising of 60pulse Gate Turn-Off thyristor VSC that is constructed becomes the GUPFC in digital simulation system and inves...

The supply current is distorted by the nonlinear load such UPS, DC drives, AC drives and arc furnace. This current harmonics derates the electrical equipments. Thus the current harmonics are reduced from the supply line using Shunt Hybrid filter. The Hysteresis controller controls the active filter thus the supply current tracks the reference fundamental current extracted by the synchronous ref...

The study of STATCOM is a connected field with the problem of reactive power compensation and better mitigation of transmission related problems in today’s world. In this review work we studied the shunt operation of the STATCOM, and how it helps in the better utilization of a network operating under normal conditions. Various devices are used for both series and shunt compensation. The learnin...
