“…3, a significant amount of papers use a type of mathematical programming, the most dominant being Mixed-integer linear programming. However, other mathematical programming types are also used [4,12,23,24]. A mathematical program refers to an optimization problem that is a function, subject to a set of constraints, that is either maximized or minimized [31].…”

It is vital to conduct the evaluation of industrial energy flexibility potential to provide knowledge to relevant market players about the energy potential with economic gain through unlocking flexibility. This paper applies a scoping review methodology and presents the findings for uncovering industrial energy flexibility. The scoping review was conducted in the last quarter of 2019, and 855 publications were found through related databases. Through a systematic quantitative and qualitative review, 26 essential publications fulfill the criteria. The result indicates that the field of evaluating the potential of industrial energy flexibility is matured with an increasing research interest. Meanwhile, the results reveal a tendency to focus on evaluating the potentials in a single process within the industrial facility. Furthermore, the result indicates that optimization is the main evaluation method. Based on the scoping review analysis and results, it was found that there is a gap between the evaluation of energy flexibility and the impact on the production flow. Hence, there is a need to focus on solutions that promote a holistic view of the production flow. Through holistic solutions, it is possible to access to which extent introducing energy flexibility measures may propagate through the production system. This can be achieved through simulation-based solutions that also promote solution validation.

Economic solutions for the integration of volatile renewable electricity generation are decisive for a socially supported energy transition. So-called energy-flexible factories can adapt their electricity consumption process efficiently to power generation. These adaptions can support the system balance and counteract local network bottlenecks. Within part of the model region Augsburg, a research and demonstration area of a federal research project, the potential, obstacles, effects, and opportunities of the energy-flexible factory were considered holistically. Exemplary flexibilization measures of industrial companies were identified and modeled. Simulations were performed to analyze these measures in supply scenarios with advanced expansion of fluctuating renewable electricity generation. The simulations demonstrate that industrial energy flexibility can make a positive contribution to regional energy balancing, thus enabling the integration of more volatile renewable electricity generation. Based on these fundamentals, profiles for regional market mechanisms for energy flexibility were investigated and elaborated. The associated environmental additional expenses of the companies for the implementation of the flexibility measures were identified in a life-cycle assessment, with the result that the negative effects are mitigated by the increased share of renewable energy. Therefore, from a technical perspective, energy-flexible factories can make a significant contribution to a sustainable energy system without greater environmental impact. In terms of a holistic approach, a network of actors from science, industry, associations, and civil society organizations was established and actively collaborated in a transdisciplinary work process. Using design-thinking methods, profiles of stakeholders in the region, as well as their mutual interactions and interests, were created. This resulted in requirements for the development of suitable business models and reduced regulatory barriers.

To reduce global greenhouse gas emissions, numerous new renewable power plants are installed and integrated in the power grid. Due to the volatile generation of renewable power plants large storage capacity has to be installed and electrical consumer must adapt to periods with more or less electrical generation. Industry, as one of the largest global consumers of electrical energy, can help by adjusting its electricity consumption to renewable production (demand response). Industrial aqueous parts cleaning machines offer a great potential for demand response as they often have inherent energy storage potential and their process can be adapted for energy-flexible operation. Therefore, this paper presents a method for implementing demand response measures to aqueous parts cleaning machines. We first determine the potential for shifting electrical consumption. Then, we adapt the automation program of the machine so that submodules and process steps with high potential can be energy-flexibly controlled. We apply the method to an aqueous parts cleaning machine in batch process at the ETA Research Factory.
