“…A simulation of the power demand of the grid shows the utilization of the planned energy converters, the coverage of energy by generators and helps with optimally dimensioning storage devices in terms of charging and discharging power as well as capacity [9]. Coupled with acquisition and operating costs, the simulation data can be used to carry out a profitability analysis, which is often indispensable for the investment decision in the new technology [10]. This results in requirements for planning on an energy-related design and the return and understandable preparation of economic KPIs for the implementation of investment decisions.…”

This paper proposes a simulation-based planning concept and a simulation architecture for the design of hybrid AC/DC grids, which have the potential to significantly contribute to the energy transition. The paper discusses the lack of knowledge for the design of these grids, and presents a simulation approach to efficiently design hybrid grids and analyze them based on an electrical simulation. The authors also address the need to include process-specific characteristics in the planning and analysis of the electrical network, which is why common simulation tools for production processes are included in the approach. This allows economical, ecological, safety-relevant and technical aspects to be integrated into the planning process. The proposed concept is further discussed and planned for validation on the basis of a demonstrator currently under construction.

“…Furthermore, the control is simplified compared to AC grids, since the provision of reactive power is no longer necessary [11,12]. Due to the increasing share of renewable energies in the overall energy mix, as well as through material reduction, the CO 2 footprint is significantly reduced [4,13,14].…”

Numerous research projects are investigating direct current (DC) grids for supplying energy to production plants. The motivation is the higher efficiency and lower material requirements compared to conventional grid structures, as fewer electrical conversion processes occur, regenerative energies can be coupled in more efficiently and recuperation energy can be stored better. The grid form and the associated earthing concept require different protective devices. The publication simulates two possible grid forms and compares the efficiency with an approximated power curve of a production cell. The publication gives researchers and plant planners an impression of how such a network is designed and which components influence the efficiency. It serves as a decision-making aid for the selection of the grid form and helps with the design of the electrical components.
