Abstract: A photovoltaic fed shunt power quality conditioner for harmonic and reactive power compensation is presented in this paper. A new control algorithm based on load active power consumption is implemented to improve the performance of the current controller under non-sinusoidal mains voltage condition. The presence of solar system decreases the voltage stress on the conventional supply system and also compensates a part of load active power during the availability of sunlight. A fixed band hysteresis current controller is used to generate switching pulses of insulated-gate bipolar transistor inverter. The concept is realised by time domain computer simulation of the model under different mains voltage, symmetrical and unsymmetrical fault on load and dynamic load condition. The viability and effectiveness of the designed PVSAF and its competence in meeting the IEEE-519 recommended harmonic standard limits is also verified through experimentation.

Keywords: hysteresis control; incremental conductance; instantaneous reactive power compensation; photovoltaics; shunt active filter; total harmonic distortion; THD; solar energy; solar power; power quality; switching pulses; insulated-gate bipolar transistor inverters; simulation.
