| Zusammenfassung |
| The supply-demand imbalance is a major concern in the presence of large shares of highly
variable renewable generation from sources like wind and photovoltaics (PV) in power
systems. Other than the measures on the generation side, such as flexible backup generation
or energy storage, sector coupling or demand side management are the most likely option to
counter imbalances, therefore to ease the integration of renewable generation. Demand side
management usually refers to load shifting, which comprises the reaction of electricity
consumers to price fluctuations.
In this work, we derive a novel methodology to model the interplay of load shifting and
provided incentives via real-time pricing in highly renewable power systems. We use weather
data to simulate generation from the renewable sources of wind and photovoltaics, as
well as historical load data, split into different consumption categories, such as,
heating, cooling, domestic, etc., to model a simplified power system. Together with
renewable power forecast data, a simple market model and approaches to incorporate
sector coupling [1] and load shifting [2,3], we model the interplay of incentives and
load shifting for different scenarios (e.g., in dependency of the risk-aversion of
consumers or the forecast horizon) and demonstrate the practical benefits of load
shifting.
First, we introduce the novel methodology and compare it with existing approaches.
Secondly, we show results of numerical simulations on the effects of load shifting: It supports
the integration of PV power by providing a storage, which characteristics can be described as
“daily“ and provides a significant amount of balancing potential. Lastly, we propose an
experimental setup to obtain empirical data on end-consumer load-shifting behaviour in
response to price incentives.
