Load Management

The projects of the “Load Management” work package are the powerhouse of NEW 4.0. It is under this umbrella that the operators of facilities allocated to the consumer side are organised. With the aid of the individual demonstrators, they provide the various load flexibilisation and storage options.

These include, for example, “power-to-heat” systems for heat generation. In these systems, the electricity taken from the grid for a short time usually replaces a fossil fuel. Demonstrators for flexibilisation of industrial production processes in terms of time and performance will compensate for fluctuating renewable energy generation, positively or negatively.

By the end of the project in 2020, a quickly adjustable potential for electrical load transfer in the two-figure to lower three-figure megawatt range is to be made available both for sector coupling and for unburdening the grid.

The objectives in this topic area are therefore identifying, modelling and supplying suitable loads. In addition, the practical requirements for structuring the legal framework governing the use of these systems and for IT integration are dimensioned and coordinated with the requirements of the distribution and transmission system operators.

Example: “Karoline” power-to-heat electric boiler and flow heaters /Vattenfall Wärme GmbH

In Hamburg‘s Karolinenviertel district, Vattenfall traditionally operates an electric boiler that is integrated into Hamburg‘s district heating system (the “Karoline“). Now, with a new electrode boiler, two flow heaters to be operated for the Allermöhe and Burgwedel-Schnelsen island networks, and modern control technology, the heating sector is to be integrated into the electricity sector (power-to-heat). The facilities will use an oversupply of electricity from renewable energy plants while simultaneously reducing the existing heat generation capacity, in order to sustainably and systematically generate heat, which will then be made available to the Hamburg district heating system and the two island networks in Hamburg. After completion, the Karoline electric boiler will have a capacity of approx. 45 MW; the flow heaters will have capacities of 1,000 kW and 500 kW respectively.
