Diseño y simulación del sistema de control para la operación de tres plantas de generación: hidroeléctrica, eólica y fotovoltaica

Abstract

This work makes the design and simulation of the contribution of three natural source generation systems: photovoltaic systems, wind system and hydroelectric system, controlled by search algorithms of maximum power of Incremental Conductance for being more efficient and more used in source systems renewable, and PI controllers that act on static power converters to later deliver this power to a common direct current bus. For the reserve of energy there is an energy storage system with Lithium-Ion batteries for storage over long periods. For the power output in the first instance, a multilevel inverter in controlled AC / DC bridge is used, with output filters and a transformer coupling with a network that can supply of energy for a variable load. The output of the system maintains a robust and rapid response to sudden changes in the input signals, these inputs have been taken from measurements made by MEER and CONELEC, with average values measured in Ecuador as they are; the wind in the central zone of the country, the lower solar radiation, and a hydroelectric system such as the Mini Central Gualaceo, all these signals measured in a daily period.
