The basic aim of the electric power sector is to produce power as when required at the suitable sites, then transmitting and distributing the same to various load centers or end users, maintaining the quality (the frequency and voltage at a specified value) as well as reliability of electrical power at an economical price. The main objective of this chapter is to have a brief idea about various power quality issues with their improvement techniques and to learn the prospects of various methods of harmonic mitigation using Active filter (both series and shunt active filters), in a Grid connected PV system with a focus on sinusoidal current control strategy as a time domain control strategy based on instantaneous pq theory. Shunt Active Power Filter is implemented in the hybrid system to mitigate the harmonic current component as well as to recompense the imaginary or reactive power owing to their exact and reckless operation, whereas Series active filter takes care of voltage sags and swells due to source or load side disturbance. The strategy so implemented using MATLAB 2016A is to extricate sinusoidal current commencing from the source. The results have been analyzed in details explaining efficacy of the above control strategy. As the control strategy is a simple and effective, it has tremendous potential for application in the Distributed Generation oriented system. Further researches can be extended toward application machine learning techniques for the improvisation of control performance of the active power filters.
