This chapter describes frequency control strategies based on nonsynchronous devices. Four scenarios are considered: (i) renewable resources operated in such a way that they have a power reserve available to regulate the frequency; (ii) converter-interfaced energy storage systems dedicated to primary frequency and rate of change of frequency control; (iii) a mix of renewable resources with inclusion of a dedicated energy storage system that allow emulating the behavior of conventional synchronous machines; and (iv) voltage-based frequency control obtained through FACTS devices, namely the static VAR compensator and the smart transformer.
Keywords: Renewable energy source; Inertia; Frequency control; Rate of change of frequency; Energy storage system; Voltage-dependent loads; Voltage-based frequency control; Flexible AC transmission system; Static VAR compensator; Smart transformer
