"Energy agents for a decentralized distribution grid management",
Presentation at: IRENEC 2026, Istanbul, 7.5.2026, online presentation.
The recently reformed German energy industry act (§14a) allows grid
operators to implement incentives to avoid grid overloading before hard
switching is applied. Here, we propose a decentralized local grid
management based on a local marked. It consists of energy agents
associated to each dispatchable load. They can communicate to each
other in the local power grid, e.g. by powerline communication or
broadcast methods.
They share bids for dispatchable power. One them acts as master and
calculates a merit order from the bids. This results in in a local
re-dispatch, which is communicated back to the agents.
The approach is simulated exemplarily for a planned energy neutral
community consisting of 36 family houses in Bergneustadt,
Northrhine-Westfalia. Each house is equipped with an electric vehicle,
a heat pump and a roof top photovoltaic (PV)-system.
The agents bid by offering a price for an amount of dispatchable power.
If global time varying energy tariffs are applicable, each agent first
calculates a price optimized dispatch plan for its component. Any
deviation of it would increase cost and this increased cost is used as
the first component of the bid. In addition, a second bid component is
calculated from the urgency of the energy need. As an example, the
closer the desired time for the charging to complete is, the higher the
bid is. Simulations with different time dependencies are performed and
compared.
