requency regulation in isolated power generation is a great challenge, especially in microhydropower where power capacity is very small. This research proposes a frequency control procedure for autonomous micro-hydropower by a combined method of flow control in hydraulic turbines with dump load control. The proposed procedure must comply with Cuban standard NC62- 04, designed for connected power generation plants. This procedure takes advantage of the advantages of both methods separately and reduces the resistive dump load, allowing an increase in the use of the primary energy resource and energy production. The state of the art of frequency regulation by flow and load controls is presented, as well as its possible combination to increase the water savings and quality of the energy generated in the autonomous micro-hydropower plants. The topic is characterized in the Cuban context and the combined flow-dump load control scheme is presented.
