Review of Power Decompositions and Theories for Load Compensation

Abstract

In this paper, various power decompositions and theories are reviewed in view of load compensation. These are necessary to evaluate the efficiency and performance of the transmission, distribution systems and various electrical equipments. In order to compensate the load, it is required to know which components of the load power or current have to be compensated. Under balanced and sinusoidal conditions, the power definitions and decompositions are well defined and are being in the practice. But, in the case of non-ideal, there is no common agreement till now about the decompositions of power and current. Hence, the power decompositions and theories for the load compensation under non-ideal conditions have become an important research area. This paper focuses on reviewing the current literature about the different power decompositions and abstract ideas for load compensation in non-ideal conditions.
