Revision de tecnicas de mitigacion en problemas de calidad de la energia en microrredes.

Abstract

This document is the result of the development of the methodology implemented for the review and determination of energy quality problems and mitigation techniques in distribution microgrid systems through the framework of the diploma in quality of electric energy offered. by the electrical engineering program of the University of Pamplona. The quality of energy has significantly detected its degree of importance since it is an issue that is relevant today both for the company that provides the service and for the end user. The considerable growth of technologies for the generation of electrical energy different from the typical form (by means of hydroelectric, thermoelectric, etc.), is the case of this review where the factors that produce disturbing events in distribution microgrids are determined. . These disturbing events are normalized by international standards (IEEE, IEC for example) and some national translations (UPME for example), in order to characterize each event according to time scales of duration and magnitudes, where the microgrids taking into account the use of power electronics, distributed generation, storage systems, control systems, mode of operation, some types of end user loads generate most of the problems such as voltage surges, voltage drops, interruptions, voltage harmonics and current among others. After describing the behavior of the disturbing event, the determination of its causes and effects, whether in the network, network equipment or end-user equipment, I will address possible mitigation techniques for these power quality problems in where, according to the bibliographic review, it is carried out by means of equipment specifically designed to counteract the affectation of the disturbing event, also supported by the bases of intelligent control to have a relationship and manipulate the variables involved in the proper functioning of the distribution microgrid as They are voltage, current and frequency among others. The robustness of the implemented control largely defines the effectiveness of the operation of the microgrid; on the other hand, the possibility of implementing the selected mitigation techniques in a national context is determined by analyzing regulations, product performance verification certificates, costs and benefits, considering that mitigation techniques are based on equipment with a specific purpose.
