How is it possible to ensure a realistic representation of the effects of fluctuating renewable energy sources on grid frequency? What temporal and spatial resolutions do energy systems need to have to do this? How can the visible effects of the increasing expansion of these energy systems be characterised and evaluated?
These questions are answered in the DYNAMOS project by expanding energy system models to include dynamic frequency regulation. High-resolution models (with up to 1 Hz resolution) are being developed to show power generation and power consumption using renewable energies.
Conventional power generation (using fossil or nuclear fuels) features an instantaneous reserve which is able to compensate for deviations at short notice in order to maintain stability in the power grid as far as possible even in the event of fluctuations. The phasing out of this conventional type of generation is leading to a reduction in energy reserves, which are less readily available through renewable energies.
Analysis of the research results is aimed at examining the effects of this reduction on the stability of the power grid and the mechanisms of grid frequency regulation. Studies are also being done on the role of renewable energy sources in maintaining grid stability.
