Agent-based Modelling Competing Flexibility Options with AMIRIS
Presenter: Johannes Kochems
Description:
This work presents a novel method for simulating the competition between flexibility options within the open agent-based electricity market model AMIRIS. To simulate competition among flexibility agents, they are equipped with an estimate of the merit-order to be able to assess both, their own price implication as well as those of competitors. As a proxy for evaluating the price impact, so-called dispatch multipliers are used. These are calculated from past awards of all flexibility units compared to the dispatch of the unit of interest. To smoothen out fluctuations, a moving average approach is used. The method has been developed for a generic representation of flexibility. So far, it has been applied to storages as well as sector coupling flexibility options, such as flexible uni- and bidirectional charging, electric vehicles and heat pumps. An extension for flexible electrolyzers is currently under development.
Background:
Flexibility is gaining increased attention in a future electricity system dominated by variable renewable energy sources. For instance, stationary battery systems as well as sector coupling flexibility from electric vehicles and heat pumps are expected to show quite a steep ramp-up. However, in order to evaluate business opportunities of these technologies, their competition and potential profit saturation needs to be accounted for. This is non-trivial for agent-based dispatch models as competition needs to be accounted for when creating a marketing schedule. The contribution presents a novel approach to address this challenge.
