Energy is of crucial importance in our society. Without energy and electricity, nothing would work – from the daily charging of our mobile phones, through to covering our basic needs, such as flushing the toilet. A key factor in energy supply is therefore having a smart and reliable energy system that manages existing resources in a demand-oriented manner along the entire power supply chain. This requires a digitalized energy grid that flexibly organizes the distribution of electricity – from generation, transport and distribution through to the consumers, who can themselves also be producers.
A current trend is towards so-called "microgrids", or island networks that supply each other and other partners in the energy network. Standardization focuses primarily on intelligent and autonomous communication models, their development and the definition of uniform interfaces to ensure communication. Standards provide solutions for the effective balancing of generation and consumption, especially at the points where energy data is exchanged within this complex system. A coordinated structure and communication between the different players provide the basis for this exchange and the resulting decentralized energy system. Another aspect is the development of a high-voltage direct current (HVDC) transmission system, also known as the "electricity highway", which transports energy over long distances with virtually no losses and thus supports optimum use of the electricity which is generated. More and more low-voltage DC lines are also being created in order to benefit from the low-loss distribution. This is resulting in changes in the different electrical voltage systems, which is giving rise in turn to new requirements for the existing power grid. Standards define these requirements and determine, among other things, the tolerances in the fluctuations. They prescribe protective distances, ensure the safe coexistence of alternating and direct current transmission and prevent kickbacks while ensuring safety during maintenance work and also consumer safety.
Not least, the energy grid of the future is expected to have a long service life. As a result of the energy transition and political policies, consumers will increasingly act as prosumers, thus drastically increasing the flexibility requirement of the grid with regard to electric cars, energy storage devices etc. Appropriate standards are being developed to rule out overloads in the power grid and to minimize the risk of blackouts.
