The use of smart electrical devices is becoming more prominent in day to day practice as they are easy to operate, more efficient and reliable. With the development of modern technology, the home appliances being used in our daily needs like: Laptop, washing machine, air conditioner, television, desktop, microwave, printer etc. are now comprehended as SMART devices. Above mentioned electronic devices are termed as non-linear devices as they work on dc voltage. The use of power converter unit to generate regulated dc power supply increases the nonlinearity in smart micro-grids and electrical systems. Due to the system nonlinearity, the insertion of higher order harmonics causes distortion in sinusoidal current and malfunctioning of devices. In this paper, the ANFIS supervised shunt active power filter with PV integration is proposed to mitigate the higher order harmonics in micro-grids and smart electrical systems. The ANFIS supervises the generation of reference current and triggers the excitation of controller with adequate switching of gate pulse to ShAPF. The proposed design is reducing the total harmonic distortion in the system as below 5% as per the IEEE standard 519. The FFT analysis on MATLAB/Simulink the proposed model for THD gives 0.29 % distortion with the use of proposed model. The novelty of the work is validated through its applications in PV integrated microgrids and experimental outcomes and energy saving in power management units. The cancellation of higher order harmonics saves power and improves energy efficiency of the system.
