“The increased penetration of Distributed Energy Resources (DER) is inspiring the entire design of conventional electrical power system. “A Microgrid (MG) includes distributed generation, loads, energy storage, and a control system that is competent of working in grid-connected mode and/or islanded mode. Power quality (PQ) problems are one of the major technical challenges in MG power system. To get better PQ of energy supply, it is essential to analyze the harmonics distortion of the system. Moreover, harmonic distortion in a MG networks has significantly reduced PQ, which affects the stability of the system. In order to diminish the harmonics, shunt active power filter (SAPF) has been extensively useful and it is verified to be the best solution to current harmonics. The present paper proposes the mitigation of harmonics of a MG system using shunt active power filter (SAPF). However, the SAPF is employed for reimbursing the harmonics concurrently in the distribution system. The proposed model is developed in MATLAB/Simulink and the result obtained validates the superiority of proposed technique over others in terms of harmonics elimination.”

Shunt active power filter (APF) is an electric equipment which effectively optimizes harmonic waves. By measuring the load current, it produces compensated current with opposite amplitude to the load current in order to improve the power quality of the power grid. Little has been reported on how to effectively design the LPF employed in the link of shunt APF and power system. The paper theoretically analyzes constrains for parameters of the LCR output filter, and then determines the optimal LRC filter parameters by comparing different output filter (OF) functions. At last, the experiment results further verify the correctness of the design method.

Power system harmonics are a menace to electric power system with disastrous consequence. Due to the presence of non linear load, power quality of the system gets affected.  To overcome this, shunt active power filter have been used near harmonic producing loads or at the point of common coupling to block current harmonics. The shunt active power filter is designed to minimize harmonics in source current and reactive power in the non linear power supplies which are creating harmonics. In this paper, Instantaneous power of p-q theory is employed to generate the reference currents and PI controller is used to control the dc link voltage. In addition to this, Artificial Intelligence (AI) technique is used to minimize the harmonics produced by nonlinear load. The main objective of this paper is to analyze and compare THD of the source current with PI controller and by artificial neural network based back propagation algorithm. The proposed system is designed with MATLAB/SIMULINK environment.
