Abstract

Decarbonization and defossilization of energy supply as well as increasing decentralization of energy generation necessitate the development of efficient strategies for design and operation of sector-coupled energy systems. Today, design and operation of process and energy systems rely on powerful numerical methods, in particular, optimization methods. The development of such methods benefits from reproducible benchmarks including transparent model equations and complete input data sets. However, to the authors’ best knowledge and with respect to design and optimal control of sector-coupled energy systems, there is a lack of available benchmarks. Hence, this article provides a model compendium, exemplary realistic data sets, as well as two case studies (i.e., optimization benchmarks) for an industrial/research campus in an open-source description. The compendium includes stationary, quasi-stationary, and dynamic models for typical components as well as linearization schemes relevant for optimization of design, operation, and control of sector-coupled energy systems.

Abstract

Bereits existierende nationale und internationale Definitionen des Begriffs Flexibilität sind zu unpräzise und werden den Anforderungen, die sich bei der Beschreibung von Flexibilität innerhalb eines zellulären Energiesystems ergeben, nicht gerecht. Diese Arbeit benennt und definiert Flexibilitätsbegriffe, um ein gemeinsames Verständnis zu schaffen. Zunächst werden die technisch-ökonomischen Flexibilitätsbegriffe Fahrkurve, Flexibilitäts-bereitstellung, Flexibilitätserbringung, Quantifizierbarkeit, Prognostizierbarkeit sowie explizite und implizite Flexibilität beschrieben. Im Anschluss werden Begriffe beschrieben, die mit der Ansteuerung und dem Abruf von Flexibilität einhergehen. Darunter fallen die aktive und passive Flexibilitätserbringung, der zustands- und kommunikationsgesteuerte Flexibilitätsabruf sowie der direkte und indirekte Flexibilitätsabruf. Zuletzt wird eine Unterscheidung anhand des Verwendungszwecks in system-, netz- und marktdienliche Flexibilität vorgenommen. Das Ergebnis sind exakte Begriffsdefinitionen und Begriffsabgrenzungen, auf deren Basis Flexibilitätsprodukte beschrieben und kategorisiert werden können, die für die Konzeption und Demonstration eines zellulären geprägten Energiesystems unabdingbar sind.

Abstract

Using batteries as energy storage is a fundamental practice to promote renewable energy generation and reduce fossil energy consumptions to mitigate greenhouse gas emissions. By integrating grid-connected photovoltaics (PV) and Battery Energy Storage System (BESS) into a local energy system, the renewable energy shares and self-consumption rate of the system can be significantly increased. Especially for high power energy users, e.g., industrial plants, energy storage even provides the possibility of peak shaving to reduce the cost of electricity and network utilization. This paper proposes a general workflow to simulate and optimize the PV-BESS system used for peak shaving in an industrial energy system, which consists of a fabrication plant for electronic devices, together with an attached office building, a battery storage system, and a PV system. The paper presents an innovative method to model the electric load of the system, considering both electric and thermal demand. The electric demand is a time-series model from the actual measurement of productionconsumption of various production machines and electric devices in the office. The thermal demand contains the electricity required from the heat pump for cooling and heating. The state-space model describing the thermal behavior of the office building is applied to the calculation. Based on the first simulation results, an energy management strategy is developed to control the proposed system. The management strategy is implemented in a lifetime simulation. Based on the simulation, the optimization problem considering the economic and environmental impact has been solved to find the optimal configurations, which minimize the annual cost of the system. The Levelized Cost Of Storage (LCOS) is integrated into the objective function. Local feed-in tariffs and environmental policies are also considered in the optimization. The simulation results are assessed in both technical and economic prospects. The optimization result provides an optimal capacity configuration of the PV and BESS system. By applying a suitable size of the PV/BESS system in the proposed industrial plant, it is possible to improve both the economic profitability and the ecological welfare by reducing CO2 emissions.
