Due to the increase of volatile renewable energy resources, additional flexibility in the electricity system is necessary to ensure a technically and economically efficient network operation. To tap flexibilities like private storages, participatory developed and user-friendly technical solutions are essential. In this work, the acceptance and the market potential of a home energy management system with focus on i) grid optimization, ii) self-consumption optimization, and iii) additional functions for increased comfort is presented. This is determined by means of a representative survey. The main results show that the perceived usefulness and accessibility are the most important influence factors affecting the end user’s intention to use. Based on the given acceptance, the solution provides a market potential of one third of the users for an increased use of flexibilities in the investigated area.

Renewable energy systems are a key enabler for a successful transition of our current energy systems. However, in every transition process numerous different interests and requirements, often diverging or opposed to each other, must be considered. “Open Innovation” approaches overcome this divergency and increase one’s own innovation potential by involving all relevant actors along the value chain. This work presents approaches, experiences, challenges, and results of Open Innovation processes applied to stakeholder groups in three different use cases. In these use cases, multi-stage, iterative processes for stakeholder integration are applied. The results of the first use case stages show a high degree of diversity in terms of different stakeholder treatment. These conflicts are tackled by the Open Innovation process, proving that a fruitful collaborative business model development is feasible.

Participation in Energy Transition - Challenges within the Scope of Smart Grids
(2018-07)
Pfeiffer, Christian
;
Rabelhofer, Marion
The inclusion and empowerment of civil society and economy are considered necessary prerequisites for the energy transition that has to be achieved. This contribution shows the process of participation approaches in general as well as a use case within the scope of smart grids in particular. The objective of this use case was to determine the users’ willingness to participate in the respective project. A participation workshop was conducted using qualitative and quantitative methods. Results show that since the participants were informed about the system solution for the first time, concern about cost and security were corollary. We conclude that the workshop served rather as instrument to inform and enlighten private end-users providing a baseline to compare results of further investigations. The forthcoming challenge is to ensure an ongoing participation process to raise acceptance and willingness to participate.

In recent years, power systems have undergone changes in technology and definition of the associated stakeholders. With the increase in distributed renewable generation and small- to medium-sized consumers starting to actively participate on the supply side, a suitable incorporation of decentralized agents into the power system is required. A promising scheme to support this shift is given by local electricity markets. These provide an opportunity to extend the liberal wholesale markets for electrical power found in Europe and the United States to the communal level. Compared to these more established markets, local electricity markets, however, neither have few practical implementations nor standardized frameworks. In order to fill this research gap and classify the types of local electricity markets, the presented paper therefore starts with the challenges that these markets attempt to solve. This is then extended to an analysis of the theoretical and practical background with a focus on these derived challenges. The theoretical background is provided in the form of an introduction to state-of-the-art models and the associated literature, whereas the practical background is provided in form of a summary of ongoing and recent projects on local electricity markets. As a result, this paper presents a foundation for future research and projects attempting to approach the here presented challenges in distribution of generation, integration of demand response, decentralization of markets and legal and social issues via local electricity markets.

On the challenges of empowering citizens in technological innovation matters
(2018-10)
Rabelhofer, Marion
;

Stöller, Julia
In order to counteract a constant global warming, the empowerment of civil society and economy are considered necessary prerequisites for the energy transition. Responsive forms of participation have to be considered in an early phase of projects and employed continuously throughout the intention. However, there are common challenges within participation processes. We illustrate a use case consisting of the implementation of technological innovations using a slow bottom-up approach. Our main thesis suggests that an active interference of social space leads to higher technology acceptance and therefore to an easier implementation of innovative technologies to increase the citizens’ quality of life. Due to the fact that our target group shows high diversity we focus on specific mediators that influence technology acceptance. Therefore, we conducted a mixed-method approach with quantitative and qualitative components. We present our main results and experiences of the first project phase in this article.

Europaweit werden im Energiebereich immer häufiger relevante Stakeholder zur Projektpartizipation herangezogen. Der gegenständliche Beitrag zeigt Erkenntnisse über die Vorbereitung und Durchführung von Partizipationsmaßnahmen im Allgemeinen sowie der damit verbundenen methodischen Herangehensweisen im Speziellen auf. Anhand von drei Projekten im Energiebereich werden die durchgeführten Partizipationsmaßnahmen mit den Stakeholdern Bevölkerung, Industrie und Politik analysiert. Die Ergebnisse zeigen einerseits den Nutzen von persönlichen Netzwerken bei der Herausforderung der Akquise von TeilnehmerInnen, die Relevanz von Marketing und Projektbewerbung, aber auch den Wissenszuwachs aller Beteiligten an der Teilhabe an Partizipationsprozessen.

This work investigates a novel distance-based electricity tariff applicable to energy communities. Based on a mixed integer linear optimization model computational studies are conducted to investigate the effects of this tariff on a small-scale community consisting of 22 consumers and 5 prosumers. Additionally, the potential of electric storage systems supporting the use of locally produced energy is investigated. The results of the computational model prove that an energy community generates incentives photovoltaic plants and the installation of energy storage systems. Complementary to the simulations, the flexibility options are supported by a user survey focusing on technology attributes for local energy market models, proving that there is a significant awareness for the use of energy storage systems.
