Techniques of Analysis and Control to Improve the Stability of Electrical Microgrids: Review in the Literature

The review presents the stability problems that are usually found in a micro-grid organized according to the nature of its causes: small signal, transient and voltage. According to the causes of the instability are associated control strategies that can improve the stability of the system. High- and low-level control strategies such as robust control, load distribution, generator control and demand are presented. Finally, strategies of sizing and siting of distributed generation units are presented, through which the stability of the system is improved.

control de alto y bajo nivel tales como control robusto, distribución de cargas, control de generadores y demanda son presentadas. Finalmente se presentan estrategias de dimensionado y posicionamiento de unidades de generación distribuida por medio de las cuales se mejora la estabilidad del sistema.
