Análisis del comportamiento de microredes eléctricas ante perturbaciones con control convencional primario

Abstract

Electric Microgrid is a small power generation plant composed of sources connected in parallel to supply electrical power in the loads can also be used as wind turbines, photovoltaic panels, among others as diesel machines, in the following document analyzes the behavior of the system with disturbances, which are directly the primary variables such as voltage and frequency, in order to obtain the most efficient control a proportional-integral controller is implemented to observe its response in steady state and transient, excitation system to maintain the voltage values in the terminals and the angle of inclination method to stabilize the frequency, to analyze the results of a non-controlled micro-network, second with control and reference gain K, third with proposed control and modified K and fourth with intentionally caused disturbances such as the increase and decrease of the load, disconnection of power lines and variation of the wind speed that enters the blades of the wind turbine. The results of this behavior show a satisfactory change, by modifying the K gain of the controller it is possible to reduce the rise and stabilization times which for the voltage and frequency variables are the most important.
