The first goal of the project is to deploy and evaluate a novel electricity distribution microgrid which al-lows a massive integration of intermittent renewable power sources while avoiding further investments into transmission grid infrastructure. Targeting industrial production environments, this microgrid relies on a DC-bus technology (instead of 3-phase AC) and thus guarantees an increased global efficiency.
The second goal is the economic and technical evaluation of the proposed semi-autonomous microgrid based grid topology under the contextual conditions with strongly reduced ribbon power production from nuclear or coal power plants.
Project objectives are:
1. Setup and operation of a semi-autonomous microgrid, suitable for an industrial production site, based on DC-bus technology which serves as power link between the renewable production (here: photovol-taics), local energy storage and consumption of energy, including the link to power-to-gas via elec-trolysis.
2. Development of the required system components in order to allow high efficiency operation and low cost hardware.
3. Development of the required regulation algorithms for power and energy management within the mi-crogrid, based on meteorological and load forecasting.
4. Smoothing the power exchange (injection and consumption) between the semi-autonomous microgrid and the distribution grid, with a 48h-in advance forecast of the time profile of the power exchange, which is guaranteed to be realized within a tolerance of maximum 1%.
5. Simulation of a superimposed distribution grid consisting of a multitude of such individual semi-autonomous microgrids, based on the assumptions and operational outcome of the demonstrator sys-tems of this project.
6. Economic evaluation of the proposed topology for the semi-autonomous DC-microgrid, comparison to an AC/DC microgrid as well as the superimposed distribution grid.

Once the project goals have been achieved the demonstrator setup will allow explaining and proving to potential industrial customers not only the system concept but also the economically relevant figures. This is a prerequisite in order to commercialize the individual technical components as well as the entire sys-tem concept. Since the system concept is conceived to be implemented at industrial production sites, the resulting demonstrator will allow convincing an industrial partner to test the system on its own production facility. For a potential customer reliability as close as possible to 100% is a key criterion of such a critical component as the electrical power provisioning and management system. For these reasons this first demonstrator is prerequis
