“…Here, a simple representation in the form of a set of power time series was chosen, whereby a combinatorial problem had to be solved. Other flexibility representations, see, e.g., in [33,34] could allow a better utilization of the actual DG flexibility. They also influence the calculation effort that individual agents have in local optimization and thus also the duration of negotiations.…”

With the transition towards renewable energy resources, the impact of small distributed generators (DGs) increases, leading to the need to actively stabilize distribution grids. DGs may be organized in virtual power plants (VPPs), where DGs’ schedules must be coordinated to enable the VPP to act as a single plant. One approach to solving this problem is using multi-agent systems (MAS) to offer autonomous, robust, and flexible control methods. The coordination of such systems requires communication between agents. The time required for this depends on communication characteristics, determined by the underlying communication infrastructure. In this paper, we investigate communication influences for the wireless technologies CDMA450 and LTE Advanced on the fully distributed optimization heuristic COHDA, which is used to perform optimized scheduling for a VPP. The use case under consideration is the adaptation of schedules to provide flexibility for regional congestion management for delivery on a regionalized ancillary service market (rAS). We investigate the scalability of the VPP and the effects of disturbances in the communication infrastructure. The results show that the optimization duration of COHDA can be influenced by the underlying communication infrastructure and that this optimization method is applicable to a limited extent for product delivery of rASs.

“…This sample is signi cant as the households involved are situated in regions with insu cient grid and supply capacity. Moreover, they represent a target group for exibility measures due to the presence of heat pumps in their detached houses, which offers signi cant potential for load shifting [34,35]. Detached houses are signi cant in energy research for several reasons.…”

Background In affluent countries, essential infrastructures like power systems are often taken for granted and thus invisible to ordinary people. However, because of energy transitions and climate impacts, the power system in countries such as Sweden is changing. For example, variable renewable power sources and increasing demand call for a potential need to be able to deal with changing conditions including disruptions at an end-use level, which makes the energy system come to the foreground. As argued in the paper, deeper knowledge about people’s sensemaking of a changing energy system is needed to support households in taking new roles. In this study, 12 interviews were conducted with people from 7 households in detached houses in Sweden participating in a trial with remote-controlled heat pumps.The aim was to investigate how householders make sense of the changing power system and possible power deficit scenarios in the future. Social representations theory and the concept of household energy resilience were used as theoretical lenses.Results Householders direct their understanding of power deficiency and changes in power supply at four different levels: household level, supplier level, national system level, and finally as a shared responsibility between the three. These insights reveal opportunities where households anticipate taking more active roles in a changing enery system – however they also identify responsibilities that other energy actors need to communicate clearly that they are taking on, to support households and the energy transition overall.Conclusions Our results show that there is potential for more active and engaged electricity end-users, beyond for example flexibility programs. However, households’ active participation, including becoming more energy resilient, is conditioned by challenges of value, involvement, and reciprocity, which are important to address as households are opening the “black box” that is the power system. The results will be of interest to professionals involved in electricity supply-related matters including suppliers, policymakers, and researchers.

“…Fonteijn et al demonstrates a generic four step congestion management approach using prosumer flexibility [6]. Several methods have also been proposed to quantify the flexibility from prosumers devices such photovoltaics (PV) and battery system, electric vehicles, heat pumps to allow interaction of prosumers with the DSOs using flexibility markets [7][8][9].…”

The possibilities to involve small-scale prosumers for ancillary services in the distribution grid through aggregators and local flexibility markets, question whether it is profitable for prosumers to oversize proactively. In this analysis, a Python model is developed to identify the cost optimal operation plan of the PVbattery system and to evaluate the device flexibility. An economic assessment is carried out to derive the costbenefit of sizing based on the mean electricity price. A sensitivity analysis is performed with the above results to study the profitable sizing of PV-battery systems with flexibility services. The results show promising advantage of oversizing although limitations prevail with the extent of flexibility services offered.
