Oliveira, F. B. R. Losses Reduction of Distribution Systems through Optimal Dimensioning of Capacitor Banks via Cross Entropy. Dissertation (Master Degree) – School Engineering, University of São Paulo, São Carlos, 2016. The distribution systems are responsible for providing electricity to residential, industrial and commercial consumers under quality standards regulated by the National Electric Energy Agency (ANEEL). Thus, utilities monitor the system to check the voltage profile in the grid and system technical losses. The latter quantity is an extremely important performance criterion, as it represents energy losses and decrease in revenue capacity of the company. Therefore, there is interest in providing electricity within specification stated by ANEEL with the lowest possible electrical losses. Techniques such as topology reconfiguration, reconductoring, allocation of capacitors and distributed generators are usually proposed in technical studies. Particularly, the allocation of capacitors is a technique that aims to identify the amount, location and type of capacitor banks (CBs), which are allocated in the system in order to minimize the losses, taking into consideration the implementation and operation costs. For this purpose, computational methods are used to determine the best configuration of CBs. Metaheuristics have been applied for the solution of this problem, with the objective to minimize the technical losses of distribution systems. This document shows the development of a solution method using the Cross Entropy metaheuristic implemented in Python programming language to reduce the losses of electrical systems modeled in OpenDSS program.
