Power consumption as frequency controlled reserve

The project developed technology for demand frequency controlled reserve (DFR) implementation, a system that automatically stops or starts electricity consumption in response to system frequency variations. The developed technology is able to supply reserve electricity and improve electricity system frequency control. The project developed two types of control: 1. External, which turns equipment on/off on the basis of frequency and established threshold values. 2. Integrated control with varying temperature set points for thermo-statically controlled consumption. The latter type responds to both high and low frequencies.
