Novel approach to measurement-based load modeling via analog and Jacobi-based methods

Abstract This paper addresses a concrete problem in the field of power engineering. Although measurement-based modeling techniques have potential to drastically improve the quality of load representation in power system studies and positively affect results, they are not applied (in industry) for reasons of computational complexity. These limitations stem from the optimization methods (e.g. Newton–Raphson) and hardware implementations (e.g. digital computer) generally employed. In this work, the authors examine a simple, alternative method which relies on Jacobi optimization and analog emulation hardware to reduce computational complexity, facilitate online applications, and make measurement-based load modeling more attractive to utilities and independent system operators (ISO’s). They hypothesize and later demonstrate that the alternative will yield results comparable to that of traditional methods.
