A time jump for dispatchers into the year 2030 / Showroom event with good response

Demonstration and discussion in the dispatcher training center (source: GridLab GmbH)

Let's assume that, after extensive after extensive reinforcement and expansion measures in the transmission network, the planned grid would be almost completed by 2030, the installed capacity on the basis of renewable energy sources is three times the peak load as in the planning scenario, and the remaining conventional power plant capacity alone would no longer be sufficient to cover the peak load. How will the dispatchers be able to safely operate this network with decentralised feed-in? Which tools are needed in the control room? To what extent will renewables already contribute to providing the necessary ancillary services? And which roles will market-oriented solutions and other sectors such as the heating market, mobility and industry play? These elementary questions on the ongoing transition of the electricity system (“Energiewende”) were the focus of the participants' discussion at the WindNODE* showroom of the project partners University of Leipzig and GridLab on 11 March 2019 in the dispatcher training centre of GridLab GmbH. About 20 representatives of Berlin Partner, Bosch, e2m, the Berlin initiative "My energy for my city", Siemens, TU Berlin and Vattenfall took part. Further participants were able to follow the event web based thanks to an online broadcast for the WindNODE Academy.

The showroom event began with an overview of the project status in the context of "Electricity market and power grid - priority rules in the energy system of the future" by the University of Leipzig and the explanation of GridLab study results for the analysis of the grid serviceability of decentralized flexibilities using the example of the power-to-heat plant currently under construction in Berlin with a capacity of more than 100 MW. Subsequently, GridLab experts demonstrated critical future grid congestions situations and operational solutions according to the classical approach up to the application of redispatch and phase shifting transformers using the 2030 planning scenario for the north-eastern German transmission system exemplarily implemented into the SCADA-based dispatcher training simulator. The limits of today's dispatcher measures were visualized and the discussion with the participants was opened. In particular, the opportunities of a comprehensive future inclusion of decentralized flexibilities as new tools for the control room dispatchers were discussed, whereby electricity market-based approaches such as "nodal pricing" and the establishment of local-regional system service market mechanisms up to dynamic network tariffs were debated as overall basis for decentralized flexibility tools. Stay tuned!

At the next showroom appointment, the implemented 2030 dispatcher training scenario will enable the demonstration of the first decentralized tools to solving bottlenecks or voltage problems by dispatchers. We will inform you in advance about the next showroom date in 2019.

 

* WindNODE is kindly supported by the Federal Ministry for Economic Affairs and Energy (BMWi) as a ‘Smart Energy Showcase’ (SINTEG) for the period 2017 – 2020. The objective is the system integration of large volumes of renewable energy while also keeping the power grids stable. Over 70 WindNODE partners work together on transferable model solutions, which can also move the energy transition forward outside of the WindNODE region. The WindNODE consortium is led by 50Hertz Transmission GmbH as transmission grid operator for electricity for North-Eastern Germany and Hamburg area.
