Electricity is all-present in our lives and it is easy to take for granted. The whole industry that is working behind the scenes to provide us with electricity is usually invisible for us.
The electricity industry is transforming and faces many technical and economic challenges. This presentation unveils the basic principles of a part of the industry that figures the most in economic analyses: electricity transmission.
The presentation also presents the role of transmission in one of the most serious electricity incidences in the last decade of the electricity grid: the 2003 Italy blackout. In this incident, Italy was first disconnected from the Continental European grid and then experienced a country-wide blackout.
Apart from being important to keep the lights on, electricity transmission also plays a crucial role in the realization of the EU Internal Market and in reaching the EU Carbon Reduction targets.
The topics I will address:
1. Limits of transmission lines
2. Dispatch (how to “send” electricity over a transmission line)
3. Frequency and stability requirements in transmission
4. The future development of the EU transmission network.
