Given the increasingly volatile prices on the power markets, it becomes economically more and more important for companies to develop and realize flexible strategies for energy consumption. A steady adaption of production processes which considers current power prices can take place on several levels of the automation pyramid, where each level has its own characteristics and requirements. In this paper, we present an optimization architecture based on an IT-platform which meets the challenges of complex multilayered production processes. We introduce layer-specific optimization strategies as well as an associated information flow, which facilitates creating holistic and well-coordinated optimizations. [less ▲]

The growing share of renewable energy generation based on fluctuatingwind and solar energy sources is increasingly challenging in terms of power grid stability. Industrial demand-side response presents a promising way to balance energy supply and consumption. For this, energy demand is flexibly adapted based on external incentives. Thus, companies can economically benefit and at the same time contribute to reducing greenhouse gas emissions. However, there are currently some major obstacles that impede industrial companies fromtaking part in the energymarkets. A broad specification analysis systematically dismantles the existing barriers. On this foundation, a new end-to-end ecosystem of an energy synchronization platform is introduced. It consists of a business-individual company-side platform, where suitable services for energy-oriented manufacturing are offered. In addition, one market-side platform is established as a mediating service broker, which connects the companies to, e.g., third party service providers, energy suppliers, aggregators, and energy markets. The ecosystems aim at preventing vendor lock-in and providing a flexible solution, relying on open standards and offering an integrated solution through an end-to-end energy flexibility data model. In this article, the resulting functionalities are discussed and the remaining deficits outlined. [less ▲]

Energy from renewable resources is not always readily available. Depending on the season and the weather, the power made available by solar parks or wind turbines varies, for example. Due to the continuous expansion of renewable energies, the volatility in the energy system will become more and more pronounced in the future. Preparing and adapting the industry to the changing supply structures is a major challenge for the next few decades. In the future, companies must be able to design their processes and operational organization in such a way that energy consumption can at least partially adapt flexibly to the volatile energy supply. In addition to developing technologies, Concepts and measures to make industrial processes more energetic, a second focus of future work is the development of a consistent IT infrastructure with which companies and energy providers can provide and exchange information from the production machine to the energy markets in the future. This leads to a paradigm shift in the operation of industrial processes - away from continuous and purely demand-driven energy consumption towards the adaptable, energy-flexible operation of industrial plants. This reference work presents the most important results of the research in the context of the Kopernikus project Synergy and clarifies trend-setting findings for further developments in the still young field of industrial energy flexibility.

Industrial demand response uses a multitude of energy flexibility measures. Their planning and control requires various production IT systems. A widely accepted approach to classify these inhouse IT systems are the levels of the automation pyramid in companies. This paper broadens the scope of this concept to overcome the limitation to companies’ (virtual) borders by including required IT systems that refine and monetarize a company’s energy flexibility, e.g. energy markets, aggregators, etc. Therefore, a holistic approach for the classification of functionalities for industrial demand response across companies and energy markets is developed and applied exemplarily.

In the course of the German Energiewende, the share of controllable power generation is decreasing, while renewable, volatile generation resources (wind turbines and pho-tovoltaics), are being expanded. Therefore, the need for flexibility on the consumer side to compensate for this volatile generation is growing, because the balance of power production and power consumption needs to be guaranteed [1]. The German industrial sector consumes the largest share by 43.7 % of electricity [2] and also holds enormous potential for load flexibility in Germany [3]. However, many potentials cannot be ex-ploited because the necessary information technology connections are missing. The ge-neric data structure presented in this paper offers an approach to describe power flexi-bility potentials in a standardized way for a prevailing situation. This state-dependent flexibility potential can thus be made available to a higher-level instance for optimizing the operation strategy. As digitization progresses, the degree of automation increases, and so does the flexibility potential of the system. To this end, the basic characteristics of flexibility are first of all worked out and the corresponding degrees of freedom are explained in more detail. The existing approaches for describing flexibility of conven-tional power plants, such as the transmission code [4], will also be discussed. There are two classes of power flexibility - time-restricted and time-independent flexibility. Sep-arate sets of flexibility indicators are created for both classes, which are then transferred to a data structure. Finally, an information architecture to process the data model is presented.

Abandoning fossil and nuclear energy sources in the long run and increasing amount of renewable energies in electricity production causes a more volatile power supply. Depending on external realities, renewable energy production emphasizes the need for measures to guarantee the necessary balance of demand and supply in the electricity system at all times. Energy intensive industry processes theoretically include high Demand Response potentials suitable to tackle this increasing supply volatility. Nevertheless, most companies do not operate their production in a flexible manner due to multiple reasons: among others, the companies lack know-how, technologies and a clear business case to introduce an additional level of flexibility into their production processes, they are concerned about possible impacts on their processes by varying the electricity demand and need assistance in exploiting their flexibility. Aside from fostering knowledge in industry companies, an IT-solution that supports companies to use their processes’ Demand Response potential has become necessary. Its concept must support companies in managing companies’ energy-flexible production processes and monetarize those potentials at flexibility markets. This paper presents a concept, which integrates both companies and energy markets. It enables automated trading of companies’ Demand Response potential on different flexibility markets. [less ▲]
