Abstract
In many countries such as Germany, the expansion in renewable power capacities in only a short time frame has been impressive. Simultaneously, conventional plants such as nuclear power plants are being phased-out of the energy system. But in contrast to conventional power plants, most of the renewable generators only pro-duce electricity if the weather conditions are right, e.g. the sun is shining or the wind is blowing. In general, there are deterministic and probabilistic methods to assess supply secu-rity. In the past, the four German transmission system operators (TSO) have used a deterministic approach (so-called forecast margin). However, with the increase of available data, we opt for a probabilistic approach to assess supply security due to its higher degree in detail of the results. Furthermore, when assessing supply security, the economic perspective also needs to be accounted for. Ideally, investments in supply security should only be made if the resulting benefits from an increase in supply security amounts at least to the in-vestment outlay. With our research, we want to contribute to the economic assess-ment of supply security.
