Reactive power definitions in single-phase circuits based on instantaneous reactive power theory
Presented by Akagi and coauthors in 1983, instantaneous reactive power theory (IRP theory) features low computational complexity and fast dynamic response, but it is not directly applicable to single-phase circuits. Scholars have been developing new approaches to define reactive power in single-phase circuits by utilizing the idea of IRP theory, i.e., mapping the voltage and current signals to a two-dimensional space with α-β transformation. This paper presents an overview of the reactive power definitions in single-phase circuits that are particularly based on IRP theory. Specifically, 3 types of definition are summarized: generalized instantaneous reactive power theory, reactive current theory, and instantaneous reactive power density theory. Furthermore, the current applications and the constraints of these theories are discussed in detail.
