Local and Central Algorithms for Distributed Generation Micro-dispatch Control

Abstract

Global growth of distributed generation, especially photovoltaic, has given rise to new markets and new problems: large injection of power at daily intervals without increasing in the level of consumption. This scenario has already created, in certain places, overvoltage problems, harmonic distortion, etc. In Brazil, the standards regulate the connection of photovoltaic inverters, however, the control is not yet subject to standardization. For this reason, this paper presents a proposal of local and central algorithms for this power injection control in accordance with the solutions of problems such as the lack of standardization in the communication protocol of the inverters. The results of the pilot plant application are also presented.
