Las energías renovables proveen el 20% de la generación de electricidad a nivel mundial, siendo la hidroelectricidad la forma más barata y sustentable de generar electricidad, representando casi un quinto de la generación a nivel mundial. En Cuba, la electrificación en zonas montañosas es a partir de pequeñas centrales hidroeléctricas aisladas del Sistema Electroenergético Nacional. Uno de los componentes más importantes en las hidroeléctricas es el regulador de frecuencia, debido a la condición cambiante de la demanda de potencia por los usuarios. El uso de sistemas de regulación ineficientes con técnicas de regulación a base de cargas resistivas o balasto, hace que se plantee la regulación de frecuencia a partir del manejo del caudal de agua como una solución técnica viable. En el presente trabajo se propone la regulación de frecuencia en la minihidroeléctrica “Hanabanilla” con un PID como controlador diseñado en Matlab Simulink y su implementación en un sistema de control a base de un PLC M241 de Schneider Electric.
