Análisis del método de control de voltaje “Droop Control” en una micro-red DC para el control de potencia activa y distribución de carga entre diferentes fuentes de generación, usando conversores de potencia

Abstract

Micro-grids have been widely accepted in recent years, due to their characteristics they allow to have systems with better reliability while being able of reducing transmission losses and they improve the use of renewable electrical energy. One of the main performance functions of a micro-network is found in the field of trade where adequate voltage profiles are managed to avoid affecting the end-user, the optimum levels of operation in this model are 0.38kV and 10kV which are affected by an increase in load causing voltage drops less than 1 pu, the alternative proposed to improve the affected voltage profiles in a micro-network is the application of the droop control technique, This is based on the configuration of active and reactive power with respect to voltage and frequency and exchanging current between the power converters, keeping the voltage profiles stable. The implementation of this control is the 10-node "IEEE AMERICAN LATINA" distribution system, which is subject to various scenarios to check its validity.
