Paradigm shift in the electrical system

Paradigm shift in the electrical system

The integration of renewable energies in high proportions within the generation structure will cause greater fluctuations in market prices, which will reinforce the active attitude of all actors and will even offer them the possibility of supporting the stability of the networks obtaining a benefit thus. Here demand aggregators, distributed generation and storage systems will find a new hole.

In the electricity market we come from a unidirectional grid situation, where energy flows from large generation centers to consumers who demand electricity in a very inelastic way and whose only role seems to be to pay the bill at the end of the month. The entry of large renewable generator parks, both wind and photovoltaic, has changed the origin of the electricity generated and diversified the ownership of the facilities somewhat, but we continue to have the same operating scheme.

However, the reduction of costs of renewable energies (especially photovoltaic), the growing use of ICTs, the development of storage technologies and their lower costs are constituting facilitators and drivers for a change in the operating paradigm not only of the electrical networks if not the entire electrical system

Where before we had a unidirectional flow, now we have a multidirectional flow caused by self-consumption facilities that discharge surpluses to the distribution networks, which will make their management more complex.

Where before we had a rigid and passive consumer, who consumed without paying attention to the market, we are moving towards the proactive and dynamic prosumer: the consumer who, beyond self-consumption or not, manages their consumption by reacting to market price signals and who You’ll gain even more manageability as storage systems become more affordable.

The integration of renewable energies in high proportions within the generation structure will cause greater fluctuations in market prices, which will reinforce the active attitude of all actors and will even offer them the possibility of supporting the stability of the networks obtaining a benefit thus. Here demand aggregators, distributed generation and storage systems will find a new hole.

On the other hand, there is a trend towards the electrification of demand that will cause a more intense use of the electrical networks, which must support this traffic. The future of mobility involves electrification, either through electric vehicles or through vehicles that use gases generated from electricity. In any case, we will transfer to the electricity grids all the load that today is supported by fossil fuels.

For all this, we are immersed in a process in which electricity distribution and transmission networks are going to support more complex flows and higher volumes, for which they will require more efficient management and exploit all the technologies and management tools at their disposal. . All this will entail a great effort in measuring, processing and controlling everything that happens in the system, forcing large amounts of information to be managed very quickly to anticipate and shorten response times.

Each one will have its place in the new system, but without a doubt the management and operation of the electrical networks will play a crucial role in integrating them all.
