AI for decentralised grid stabilisation


In a sustainable energy future, small decentralised plants such as combined heat and power (CHP) plants, heat pumps or biogas units must assume the role of stabilising the transmission system, a task which is nowadays mainly performed by large, centralised power plants. To investigate the technical feasibility of decentralised stabilisation options, TSCNET shareholder TenneT, the Dutch-German transmission system operator (TSO), the distribution system operator (DSO) Bayernwerk and Consolinno Energy GmbH have now jointly carried out a successful test in the southern part of the TenneT control area, the German federal state of Bavaria.

Since there is a vital public interest in such future-oriented technological solutions, the test was funded by the German Federal Ministry for Economic Affairs and Energy in the framework of the research project “C/Sells” which is part of the innovation programme “Smart Energy Showcases. Digital Agenda for the Energy Transition” (“Schaufenster intelligente Energie. Digitale Agenda für die Energiewende” – SINTEG). During the test, at the request of TenneT, the feed-in of a CHP plant controlled by Consolinno and connected to the low and medium-voltage grid of Bayernwerk was increased in order to provide the grid with the electricity required for stabilisation in the event of a bottleneck.

What is new is that each plant autonomously determines its flexibility potential through artificial intelligence (AI). The respective potential of the individual plants can then be further aggregated by means of swarm intelligence. The plants are in normal marketing and operation mode and report free flexibility quantities to the grid operators. “In Bavaria alone there are several thousand CHP plants, heat pumps and biogas facilities, nationwide there are many thousands more. They can increase the flexibility of the energy system and thus contribute to a safe and decentralised energy system in Bavaria and Germany. David can thus become Goliath,” comments Tim Meyerjürgens, COO at TenneT. Also in several other cooperative pilot projects, the TSO is exploring the potential of decentralised flexibility.
