Electricity is the major & predominant source of energy in today's perspective. With the advent of technology & increase in buying capacity of household's, the usage of Heavy Electric Load's such as Air Conditioner, Hooters, Washing Machines have seen a drastic rise. Also, unlike industrial loads are much heavier, they run in a fixed pattern & generally load is balanced across all three phases & are seldom nonlinear. Also, proliferation of electronic equipment has increased the Non-Linear load such as SMPS, which have rectifier component in line, & introduction of Inverter Technology for Ac's & Washing Machines, despite saving energy, has created severe concern of harmonic / high frequency noise introduction in Power System. The proposed system intends to implement a Shunt Active Power Filter using PI (Proportional Integral) Technique that can cater to power system harmonic & noise introduced by Non-Linear Load, Unbalanced Load & Mixed Load.

“…The methodology of the P and PI controllers demands a precise linear mathematical model, which is hard to have available, and it also cannot perform satisfactorily or provide a good response under parameter variations, nonlinearity, or load disturbances, and in fact, the transient response is slow, especially for fast‐changing loads. In this work, our objective is to design a model based on a new Lyapunov function for DC voltage control, which allows a very good dynamic with and without variations in loads, unlike the control used in previous works . Furthermore, the fuzzy logic controller has certain drawbacks, such as iteration and redundancy problems, and for the controller based on NFC, in the case of changes in the DC voltage reference, the DC voltage response follows its reference slowly .…”

The three-phase four-wire shunt active power filter (SAPF) was developed to suppress the harmonic currents generated by nonlinear loads, and for the compensation of unbalanced nonlinear load currents, reactive power, and the harmonic neutral current. In this work, we consider instantaneous reactive power theory (PQ theory) for reference current identification based on the following two algorithms: the classic low-pass filter (LPF) and the second-order generalized integrator (SOGI) filter. Furthermore, since an important process in SAPF control is the regulation of the DC bus voltage at the capacitor, a new controller based on the Lyapunov function is also proposed. A complete simulation of the resultant active filtering system confirms its validity, which uses the SOGI filter to extract the reference currents from the distorted line currents, compared with the traditional PQ theory based on LPF. In addition, the simulation performed also demonstrates the superiority of the proposed approach, for DC bus voltage control based on the Lyapunov function, compared with the traditional proportional-integral (PI) controller. Both novel approaches contribute towards an improvement in the overall performance of the system, which consists of a small rise and settling time, a very low or nonexistent overshoot, and the minimization of the total harmonic distortion (THD).
