A stable power supply is the focus of current energy debates. The ultimate target is to become independent from fossil fuels. However, the change from a few centralised energy producers to many decentralised ones means a complete reorganisation of the power grid, which has existed in this form for over 100 years, something that isn’t entirely without risk.
The change to decentralised energy production carries many risks, not least that grid stability could be jeopardised. To avoid this scenario, the decentralised plants must contribute to grid stability in two main ways. On the one hand, autonomously based on the available amount of energy produced in conjunction with the grid frequency, and on the other, centrally controlled by grid control centres, mostly aimed at regulating the active power.
