Slide 2: Agenda
Agenda 1. Voltage regulation – reminder of key principles 2. Observed evolution of voltage regulation needs on ELIA’s grid – 2013 3. Geographic constraint for voltage regulation 4. Evolution of Elia’s grid and production park 5. Conclusions 6. Practical aspects 2
Slide 3: Voltage regulation – reminder of key principles
1. Voltage regulation – reminder of key principles Voltage on Elia’s grid evolves following its load and physical characteristics of its elements ( ex: cables are strongly capacitive when slightly charged and produce Mvar) If load , U (voltage) If load , U (voltage) Production of reactive Abso
Slide 4: Observed evolution of voltage regulation needs on ELIA's grid - 2013
2. Observed evolution of voltage regulation needs on ELIA’s grid - 2013 Opposite needs for reactive power occur at the same P load more frequently than Absorption needed before. (ex: high importation level requires injection of reactive power ) Injection needed Increasing volatility of the future ne
Slide 5: Geographic constraint for voltage regulation
3. Geographic constraint for voltage regulation Need for reactive power vary significantly within Elia’s electrical zones (ex: zone Brussels) Mvar cannot easily be transported on electrical grid (losses, instability,…) Absorption needed Injection needed 5
Slide 6: Evolution of Elia's grid and production park
4. Evolution of Elia’s grid and production park Increasing capacity at interconnections Infrastructures on Elia’s grid : increasing installation of cables Our grid becomes more capacitive than before Need for diversification of sources of reactive power Temporary or definitive closure of cla
Slide 7: Conclusions
5. Conclusions Increasing volatility of needs How? By analyzing Need for possibilities for diversification industrial customer to Evolution of ELIA’s of sources participate grid and production park Before being able to determine functioning rules (remuneration, activation, …) to possibly use other s
Slide 8: Practical aspects
6. Practical aspects ELIA wants to send its questionnaire before end of October Industrial customers are kindly asked to answer before 31/11/2014 and send the questionnaire back to thibaut.gerard@elia.be Questions / ELIA contact point : Thibaut Gérard or via your Key Account Manager Thibaut GE
