This paper studies the possibilities of decomposition of the current in three-phase, three-wire systems based on the classic p-q theory. Recently, the energy crisis in the world has led to the rise in use of renewable energy sources with the advancement in power electronics technology, the solar photovoltaic energy has been recognized as an important renewable energy resource because it is clea...

Selection of proper reference compensation current extraction scheme plays the most crucial role in the performance of an active power filter (APF). This paper mainly describes three different control schemes used in APFs namely, Conventional instantaneous active and reactive power (p–q), Modified p–q, and Instantaneous active and reactive current component (id–iq) schemes. Our objective here i...

Recently wide spread of power electronic equipment has caused an increase of the harmonic disturbances in the power systems. The nonlinear loads draw harmonic and reactive power components of current from ac mains. Current harmonics generated by nonlinear loads such as adjustable speed drives, static power supplies and UPS. Thus a perfect compensator is required to avoid the consequences due to...

Nowadays, AC charging piles are widely used, and with the increasing number of piles, harmonic pollution generated by them becomes more serious affects power quality grid. Aiming at problem control single-phase pile, it is decided to apply active filter technology. The parallel (PAPF) selected according characteristics pile. single detection method studied based on instantaneous reactive theory...

In a modern power system, the unified quality conditioner (UPQC) is considered to be most effective device for mitigating problems. The use of dynamic voltage restorer (DVR) active-reactive power-sharing reduces loading on UPQC in all operating conditions, leading better system efficiency and reliability. VA DVC can controlled by maintaining proper angle between load source voltage. this paper,...

This paper addresses power quality compensation with a constant DC-capacitor voltage-control (CDCVC)-based reactive control method for three-leg pulse-width modulated (PWM) rectifier in bidirectional battery charger (BBC) electric vehicles (EVs) commercial single-phase three-wire low-voltage feeders, considering two domestic consumers. The instantaneous flowing into the PWM demonstrates that ba...

This paper, propose a Three-terminal Reduced DC Bus Capacitance Unified Power Flow Controller (UPFC) for Low Voltage (LV) distribution Networks with High Photovoltaic (PV) penetrations. The device is shown capable of voltage regulating and correcting phase unbalance voltages that can be produced by high levels of distributed photovoltaic (PV) generation. The device is also capable of Power fact...

The recruitment phenomenon, that is, the reduced dynamic range between threshold and uncomfortable level, is attributed to the loss of instantaneous dynamic compression on the basilar membrane. Despite this, hearing aids commonly use slow-acting dynamic compression for its compensation, because this was found to be the most successful strategy in terms of speech quality and intelligibility reha...
