Descripción
Flywheel energy storage systems (FESSs) have proved to be an effective solution to mitigate the impact of renewable energies in the quality of the system frequency. Fast inertial and frequency response, high round-trip efficiency, and high capability to withstand frequent charge-discharge cycles, are the main properties of this energy storage system. The objective of this paper is to analyze the contribution of a FESS to reduce the impact of wind power variability on the frequency of an isolated wind-hydropower system based on El Hierro island (Spain). This has been evaluated by means of simulations, considering different control strategies and number of flywheels (NF) in the FESS. The simulation model considers the long-term dynamics of both the pumped storage hydropower plant (PSHP) and FESS (hydraulic and mechanical transients), as well as the inertial response of the transmission network to generation-demand imbalances, caused by variations in the wind power generation, which is considered as input data. Two different control strategies are considered: droop-based (DB) and nonlinear proportional (NLP). Both control strategies are compared in terms of the average and maximum frequency deviations, PSHP regulation effort and FESS number of charge-discharge cycles. The results demonstrate that in general the FESS helps to reduce the frequency deviations although the optimal NF strongly depends on the flywheels control strategy; a higher NF does not guarantee a better system frequency response.
