To reach the 100% renewable power supply goal, the power system needs to change its design and operation. Silicium needs to substitute copper. Power electronics-based control approaches need to substitute electro-mechanical ones. After 5 years of the Young Investigator Group "Hybrid Networks" project in our Power Hardware in the Loop (PHIL) Lab funded by the Helmholtz-Gemeinschaft / Helmholtz Association, we are introducing the concept of Asynchronous Grid, where we imagine the system partitioned in smaller power electronics-fed sub-networks, which frequency and voltage is managed locally by a converter. This approach opens to a new world of control possibilities: - Frequency and voltage can be easily controlled locally, and we can focus on a direct-power control of the asynchronous-grid. - Decision-making processes are distributed in the grid to each sub-network, reducing the need for complex optimisation problems, and only the asynchronous connection points need to coordinated. - Frequency and voltage-dependent loads and generators can participate in the mains frequency control, by contributing in varying their power following a frequency or voltage variation signal.
