Resumen:
Underfrequency load shedding (UFLS) is a last resort tool to arrest the decrease in frequency and avoid the collapse of the system in case of a disturbance. Wind power has experienced a wide development throughout the world due to technological progress in wind turbines and favorable policy incentives. There is a need to verify if the actual UFLS schemes are suited to the expected wind power increase. The feasibility of an UFLS scheme is addressed by analyzing actual and future scenarios of generation and taking into account probable contingencies
within each scenario. This paper describes how future scenarios can be estimated and how the contingencies have been chosen. It also details the values and measures proposed for the assessment of the adequacy of an UFLS scheme. Finally, this paper analyzes an UFLS scheme in current and future generation scenarios of an isolated Spanish power system.
Palabras clave: Load shedding, frequency stability, wind power generation.
