The structure of the European power grid
Power grid and its operation constitute the backbone of the entire electrical system: it holds together all elements that result in the supply of electricity.

Use of Balancing Power
Keeping the balance – all the time
System operation is a real-time business that needs to keep the balance between production and consumption at any time.

What TSOs do all day long
Synchronous operation of a system means sharing benefits (e.g. costs of reserves) and risks (propagation of disturbances) of a joint operation.
TSO job description:
maximize the benefits while minimizing the risks

The main reasons for the new reliability challenges
generation no longerclose to consumption
lack of allocation signals
increasing average transport distancecauses increasing losses

place generation close to the demand
transport of primary energy is less expensive than transport of electricity
proper allocation signals to generators release congestions
generation should be based as much as possible on renewables to achieve the climate goal
But: take note that wind energy will always be an challenging ad on but no reliable source for the security of supply, because you can‘t schedule the wind
Lessons learnt from the scenario
