The reactive power quadrants in electric meter refer to dividing a plane coordinate system into four regions, with the horizontal axis representing reactive power and the vertical axis representing active power. Each region represents a different combination of reactive power and active power states. These four regions are known as quadrants I, II, III, and IV, each with its own meaning and ...
This includes the modelling of PV module and the power conditioning unit interfacing the PV to the utility grid with proper power flow control. The output of the PV panel is connected to the DC–side of the voltage source inverter for interfacing to the grid. The maximum power point tracking, grid synchronisation, ...
The voltage difference between two nodes is strongly affected by reactive power flow. In contrast to frequency control, node voltage control must be achieved locally. This article investigates the use of a wind farm based on a doubly fed induction generators (DFIG) for reactive power ...

Reactive Power Optimisation (RPO) is an important issue in deregulated electricity market. This paper presents a Hybrid Particle Swarm Optimisation (HPSO) approach for solving the RPO problem in electricity market. Particle Swarm Optimisation (PSO) is a population-based search algorithm for global optimisation and has a minimum number of control parameters. In the proposed HPSO, to avoid the ...
This paper deals with a wind energy conversion system (WECS), based on a doubly fed induction generator (DFIG) and an electromechanical active power filter (APF). The objective is to respond simultaneously to electric energy requirement and power quality concerns. The proposed WECS is able not only to track the maximum power point of the wind energy but also to dampen harmonic currents from the ...
The increasing energy demands, insufficient availability of power generation and increasing global environmental problems, need alternate/green power sources.
