Field test to demonstrate a smart market platform via smart meter infrastructure
Abstract
The deployment of smart market approaches as well as the implementation of smart meter infrastructure are tools to face the challenges which come along with the continuing transition of the energy system. This paper describes a field test of the application and use of smart markets and smart meter infrastructure in combination with one another, and points out constraints limiting their implementation. Besides the technical perspective, the importance of user participation in the field test to obtain findings regarding the usability of the concept is discussed
The transition to a climate-neutral energy system involves the integration of many small components—on the generation as well as on the consumption side. Their controllability is a crucial part of running a reliable energy system, for example, to prevent or resolve grid congestions. The smart meter infrastructure enables a secure integration of these small system units in grid operator processes. The technical realization of German smart meter infrastructure is detailed in the guidelines of the German Federal Office for Information Security. It must undergo certification before being deployed. In order to assess whether the standardized German infrastructure meets the requirements for the use case, we conducted a performance analysis including the three factors “overall reliability”, “emerging data volume”, and “latency time”. The investigated use case is “Load Management through Grid Operators”. For data collection, we used log records from all participating devices along the process chain and recorded all network traffic. In total, we executed over 2000 commands within the test series and analyzed over 3.0 mio. data points. We concluded 98.2% successful power limitations for the overall reliability. The average emerging data volume is 14.97 kB when executing one command within one communication session. The latency time from the command until the reaction is on average 51 s, referring to the case of a curative power limitation and needing to establish a communication channel. Thus, the requirements for the considered use case are fulfilled, provided that the capacity of communication infrastructure is made available according to the number of controllable components.
A cellular power system requires new coordination mechanisms to overcome the challenges posed by distributed generators and new electrical loads. Within the project C/sells, different living lab approaches deployed small-scale cross-sector flexibility options for grid- and system services. Building on that, this chapter describes a comprehensive organizational framework to promote the formation of energy communities from neighborhood to federal level. The presented platform architectures offer new business models for their participants and intelligently bundle the collective effort to provide ancillary services for improved grid stability. However, in addition to the technical foundation, further participatory endeavors and new shareholding options should be discussed to support a self-sustaining bottom-up movement.
The ongoing decentralisation of the energy system leads to an increasing number of technical units across all sectors. In the future, these components will be required to provide grid and ancillary services and thus gradually take over tasks that were previously provided by a central structure. To ensure a secure and interoperable infrastructure, intelligent metering systems (smart meter or iMSys) that are being rolled out must also be actually deployed. As the services have different technical requirements, these must be compared with the properties of the iMSys infrastructure. Since there are different approaches to the design of the iMSys infrastructure across the European countries, this paper presents with the House of Quality a methodological approach for the systematic comparison of requirements (services) and properties (iMSys) as well as a quantification of the implementation potential of the services. This provides an assessment of the relevance of individual functionalities for the implementation of services and enables the identification of functional gaps. Furthermore, the method is applied to 25 selected services and the different iMSys generations in Germany. This shows that available iMSys are very limited in their support of services (5 out of 25) but this number goes up to 21 with the coming iMSys generations. As a result, the feasibility of services is determined and missing functions are identified that enable the application of all considered services and thus provide the basis for a smart energy system. The method, as presented here for Germany, can be adapted for other countries with the individual framework conditions.
The heated controversy over “citizen participation,” “citizen control”, and “maximum feasible involvement of the poor,” has been waged largely in terms of exacerbated rhetoric and misleading euphemisms. To encourage a more enlightened dialogue, a typology of citizen participation is offered using examples from three federal social programs: urban renewal, anti-poverty, and Model Cities. The typology, which is designed to be provocative, is arranged in a ladder pattern with each rung corresponding to the extent of citizens' power in determining the plan and/or program.
