In this paper, the impuissance of traditional ip-iq method in reactive power compensation applications under nonideal mains voltages is illustrated first, and then a novel current reference calculation method for Shunt Active Power Filter (SAPF) based on p-q transformation is proposed. By means of the proposed method, the positive sequence fundamental active current component of the load current can be isolated under distorted and/or unbalanced mains voltages, which makes SAPF be capable of harmonic cancellation and reactive power compensation at the same time under nonideal mains voltages. The effectiveness of the new proposed method is mathematically studied and verified by computer simulation under ideal and nonideal mains voltages.

Shunt active power filter (SAPF) has now become a well-known sophisticated technology to overcome current harmonics and reactive power compensation issues. In this paper a technical review of various control strategies for operation of SAPF has been presented. Control strategies such as reference current generation by time domain, frequency domain and soft computing approaches; voltage control for dc link voltage regulation and current control for generating switching patterns for voltage source inverter has been discussed. This paper aims to provide a broad understanding on SAPFs for various research and engineering applications.
