“…Often, these applications are sandboxed, i.e., they are running in a closed environment and can then communicate only via these system interfaces, allowing for a controlled environment and thus assuring security and privacy guarantees. A more detailed overview of infrastructural research can be found in [52] (focusing on connectivity issues) and in [35] (focusing on interoperability frameworks).…”

Toward an Effective Community Energy Management by Using a Cluster Storage

The integration of renewable local energy generation in single households -turning the household into a ''prosumer'' -is an important way to support an ecological transition of the electric power system. However, due to the volatile and distributed nature of most renewable energy sources, the power system may face stability problems when integrating a large number of renewables. The paper at hand describes an approach to overcome these shortages in a two-fold manner: First, the effects of the installed renewables shall be limited locally to a group of households -a so-called ''energy community''. To do so, all the participating households are using existing self-consumption optimization tools. However, when a household has excess energy which can not be consumed locally, this energy is shared among the other participating households by using a cluster storage device, thus enabling a community self-consumption before feeding into the low-voltage distribution grid. Second, the connected operator may request flexibility from the participating households. For that, additional loads or load sheds are triggered by the requesting grid operator, depending on the current situation in the grid. The households decide autonomously about the amount of granted flexibility, receiving respective financial incentives. This work introduces an energy management concept and a prototypical control infrastructure used for the aforementioned functionalities. In a number of simulations and field tests, the proposed approach was successfully evaluated. The article provides a comprehensive overview of the gained results and the conclusions derived from them.

“…Other publications in this context deal with topics like mathematical description and reliability assessment methods [2] and onboard fault diagnosis [3]. An approach for coping with these requirements by implementing a virtualization layer for power supply systems by using techniques known from information technology is presented in [4]. For aviation applications, the requirements for functional safety have always been even stricter.…”

This paper applies basic swarm robotics concepts to the control of a redundant multi-source power supply system for an automotive onboard grid. The fundamental concepts and thoughts are explained to give a basic understanding of swarm robotics engineering, redundant vehicle power system structures, DC-DC converter modeling and control. A simplified example application is modeled and simulated as a first proof of concept. The results show the feasibility of the artificial swarm intelligence based concept. The numerical assessment shows significant improvements in dynamic control quality, bandwidth, stability, robustness and fault tolerance without the need for additional dedicated communication compared to a traditional single-source solution. In a second simulation, an adaptive and fault tolerant PWM carrier shift optimization is successfully realized. This demonstrates an even more advanced technical feature in addition to a pure high-stability voltage regulation and gives an outlook to the new possibilities opened up by applying swarm robotics concepts.

Open Information Architecture for Seamless Integration of Renewable Energy Sources

Electric power systems are currently confronted with a fundamental paradigm change related to its planning and operation, mainly caused by the massive integration of renewables. To allow higher penetration of them within existing grid infrastructures, the “smart grid” makes more efficient use of existing resources by integrating appropriate information technologies. Utilising the benefits of such smart grids, it is necessary to develop new automation architectures and control strategies, as well as corresponding information and communication solutions. This makes it possible to effectively use and manage a large amount of dispersed generators and to utilise their “smart” capabilities. The scalability and openness of automation systems currently used by energy utilities have to be improved significantly for handling a high amount of distributed generators. This will be needed to meet the challenges of missing common and open interfaces, as well as the large number of different protocols. In the work at hand, these shortcomings have been tackled by a conceptual solution for open and interoperable information exchange and engineering of automation applications. The approach is characterised by remote controllable services, a generic communication concept, and a formal application modelling method for distributed energy resource components. Additionally, the specification of an access management scheme for distributed energy resources, taking into account different user roles in the smart grid, allowed for a fine-grained distinction of access rights for use cases and actors. As a concrete result of this work, a generic and open communication underlay for smart grid components was developed, providing a flexible and adaptable infrastructure and supporting future smart grid requirements and roll-out. A proof-of-concept validation of the remote controllable service concept based on this infrastructure has been conducted in appropriate laboratory environments to confirm the main benefits of this approach.
