Abstract
With the increase in awareness of global warming, governments have put more emphasis on a higher share of renewables in the electricity generation. Several attractive schemes have been introduced by several countries such as Germany to reach the set targets. However, the costs of technologies for harnessing energy from Renewable Energy Sources (RES) have reduced substantially. As a result, the regulating authorities have reduced the incentives to renewable energy producers affecting their economic trajectories. Considering the volatility of the RES, the System Operators (SO) incur higher costs in integrating the generated energy. The European Union (EU) aims to decarbonise its power system by 2050, resulting in a much higher share of RES in the power mix. To reduce these costs, flexibility options for energy consumption are necessary. One of these options might be developed within net-zero energy factories. The flexibility offered by net-zero energy factories is non-specific and needs to be evaluated on a case-by-case basis.
This thesis aims to evaluate the flexibility options within net-zero energy factories and study the impact of exploiting these options. A case study on the manufacturing of steel ingots was done. Real-time optimisation of the processes and sizing of the Photovoltaic system, energy storage system and material storage system was implemented using the software Anylogic. The execution controls the energy consumption of the manufacturing process targeting minimum energy exported to the grid, thereby reducing the disturbances in the network. In this case study, given the boundary conditions, it has been observed that the impact of material storage is limited in comparison with energy storage. As a combination, however, maximum flexibility was observed.
