Maps of Intrinsic Cost (IC) in reliability problems of medium voltage power distribution systems through a Fuzzy multi-objective model

Abstract

In this work the reliability of a real Medium Voltage Power Distribution Systems (MVPDS) with the application of Sectionalizing/Protection (SP) Devices is analyzed. The most satisfactory solution is obtained through a metaheuristic X-PSO with extension to the fuzzy domain. The main contribution of this work is the simplification of the index called Intrinsic Cost (IC) and the analysis of the criteria of reliability of Device cost and Energy Not supplied. The IC enables to obtain the economic valuation of each one of the criteria to be optimized, and it is based on the clause 'Ceteris Paribus'. The problem, the model and the solving method used are described. An extensive analysis is performed through two-dimensional graphs (maps) of the economic valuation of the criteria optimized from their respective Intrinsic Costs. Finally, the real case study of the problem of the reliability optimization and the results obtained are analyzed.
