The sharp rise in the share of electrical energy fed in on a decentralised basis presents electricity grids with new challenges. Decentralised energy plants depend on smoothly functioning transmissions grids with a “go-between” to forward their electricity at all times to consumers who need electricity right then. The volumes of electricity generated and consumed have to be in balance every single second. That’s especially complicated when the volume of electricity generated is based not on current consumption levels in the grid, but rather on external factors such as wind and solar radiation. The complexity of the whole system grows with increasing numbers of plants connected. As a result, the increase in the share of both decentralised and centralised generation from renewable energy sources that is both expected and also called for by politicians makes it necessary to enhance distribution grid technology.
