An application of multicriteria decision aid in switching state control of a hybrid electric power generation network

Abstract

This article presents the implementation of a multi-criteria decision support method in the management of multi-source switching systems. We implement the Analytic Hierarchy Process (AHP) in order to solve problems relating to multi-source switching systems. This method reduces undesired multiple switchings bothering the output signal and perceived as electrical perturbations for sensitive charges. The advantage of this approach is that it makes it possible to compare several criteria that are difficultly customisable, using a sole optimisation function. As solution to curb issues relating to the implementation of AHP in real time as descrribed in the literature, we propose an algorithm for aggregating criteria, sub-criteria and alternatives, of which the ultimate goal is to switch to the alternative source offering the best compromise amongst a variety of contradictory. To approve the proposed AHP method, we implement an expert source management system in a Labview environment, which reproduces the same switching conditions in real time.
