POWER GENERATION CONTROL CENTER, ELECTRICITY NETWORK DELEGATE
The Generation Control Center of the Instituto Tecnológico y de Energías Renovables (CCG-ITER) supervises in real time the operation of 145 renewable electricity production facilities, totaling more than 51 MW.
It operates 24 hours a day, 365 days a year and manages data from 3 wind farms, 7 photovoltaic plants and more than 135 individual photovoltaic installations from different groups.
Renewable energies present certain unique characteristics, mainly due to the dispersion of this generation, the variability of its production determined by changing environmental conditions, the uncertainty in its prediction and the technology used in many of the generators. All these variables must be taken into account to guarantee the required levels of supply quality, including the correct balance between production and electricity consumption.
According to Royal Decree 413/2014, all production facilities from renewable energy sources, cogeneration and waste, in electricity systems in non-peninsular territories, with installed power greater than 0.5 MW, and those with installed power less than 0.5 MW but forming part of a group whose total installed power is greater than 0.5 MW, must be attached to a Generation Control Center (CCG) and have Real Time Telemetry (TTR).
The high number of producers in the electricity system requires a secure and efficient interlocution between REE and the generators, and requires the assignment of these to Generation Control Centers. The GCCs receive information from the generators assigned to them, transmit it to the Renewable Energy Control Center (CECRE) and, if necessary, transmit CECRE’s orders to the generators to ensure that renewable energy can be safely integrated into the electricity system.
The CCGs must have an adequate connection with REE’s control center, have sufficient control, command and monitoring capacity over the generation assigned to them and have the appropriate training of their human resources to guarantee a secure interlocution with Red Eléctrica and its functionality 24 hours a day, every day of the year.
