Optimal Real Time Data Treatment and Displaying Helps the System Operator Make the Right Decisions, Ensuring Security of the Electrical System
Reliable operation of the electrical system is an essential service that Red Eléctrica de España (REE) implements in its two basic roles: transmission and system operation. To implement such functions, the transmission grid is operated by REE, who coordinates its use with the generation facilities to continually monitor and provide the continuity and security of the electricity supply.
This complex process requires the availability of high capacity telecommunications and computerized systems which display the information received in real time from all the facilities and participants of the electrical system. REE’s control system must monitor and manage more than 220,000 variables (90,000 analog and 130,000 digital) at intervals of four, eight and twelve seconds, and issue remote control instructions through 40,000 signals.
Due to the amount of data received, processing and making all the information received at both the Electrical Control Centre (CECOEL) and the Control Centre for Renewable Energy (CECRE) easily available to the system operator is essential for optimal decisions.
Gathering and managing real time data from the renewable energy facilities with more than 2,800 distributed sources in Spain, together with the telecommunication deployment carried out among generation, transmission and operation activities has been one of the pillars that has allowed Spain to reach high penetration of renewable energy. This helped cover 35 % of the demand by renewable energy during the last three years and allowed the system to be operated some days with more than half of its demand supplied by variable renewable energy (64 % of demand supplied by wind generation was reached on 24/09/12).
