Electric vehicles and renewable energy sources are collectively being developed as a synergetic implementation for smart grids. In this context, smart charging of electric vehicles and vehicle-to-grid technologies are seen as a way forward to achieve economic, technical and environmental benefits. The implementation of these technologies requires the cooperation of the end-electricity user, the electric vehicle owner, the system operator and policy makers. These stakeholders pursue different and sometime conflicting objectives. In this paper, the concept of multi-objective-techno-economic-environmental optimisation is proposed for scheduling electric vehicle charging/discharging. End user energy cost, battery degradation, grid interaction and CO2 emissions in the home micro-grid context are modelled and concurrently optimised for the first time while providing frequency regulation. The results from three case studies show that the proposed method reduces the energy cost, battery degradation, CO2 emissions and grid utilisation by 88.2%, 67%, 34% and 90% respectively, when compared to uncontrolled electric vehicle charging. Furthermore, with multiple optimal solutions, in order to achieve a 41.8% improvement in grid utilisation, the system operator needs to compensate the end electricity user and the electric vehicle owner for their incurred benefit loss of 27.34% and 9.7% respectively, to stimulate participation in energy services.
This report is intended to collect, present, and evaluate the various solutions applied in individual operational pilots for their (upscaling and transnational transfer) potential, in terms of opportunities and barriers, over the short and long(er)-term. This is done by identifying the main characteristics of the solutions and sites and the relevant influencing factors at different local (dimension) contexts.The analysis provides insights in barriers but also opportunities and conditions for success across four main dimensions that make up the local context landscape. We consider two main roll-out scenarios:1. Upscaling within the boundaries of the country where the operational pilot (OP) took place2. Transnational Transfer relates to the potential for transferring a (V4)ES solution to any of the other three (project) countriesThere are several aspects within the four main dimensions that are cross-cutting for all four countries, either because EU legislation lies at its roots, or because market conditions are fairly similar for certain influencing factors in those dimension.Ultimately, both Smart Charging and V2X market are still in their relevant infancies. The solutions applied in various SEEV4-City pilots are relatively straightforward and simple in ‘smartness’. This helps the potential for adoption but may not always be the optimal solution yet. The Peak shaving or load/demand shifting solutions are viable options to reduce costs for different stakeholders in the (electricity) supply chain. The market is likely to mature and become much smarter in coming 5 – 10 years. This also includes the evolvement (or spin-offs) of the solutions applied in SEEV4-_City as well. At least in the coming (approximately) 5 years Smart Charging appears to have the better financial business case and potential for large scale roll-out with less (impactful) bottlenecks, but looking at longer term V2X holds its potential to play a significant role in the energy transition.A common denominator as primary barriers relates to existing regulation, standards readiness and limited market availability of either hardware or service offerings.
Professional interventions are rarely successful when used to “normalize” the behaviour of a disruptive group of Dutch-Caribbean migrants. Surprisingly a large number of professionals have not succeeded in assimilating a relatively small group. Foucault developed a means of analysing power mechanisms, which is essential to understanding how non-conformist groups are turned into “normal” subjects. If, following Foucault, we conceive of professional interventions as power strategies, we may wonder what might undermine their effectiveness. This is part of a broader research question which asks whether Foucault’s description of normalizing power offers sufficient means to describe power strategies as reciprocal interaction. My thesis is that the concept “logics”, as used by Mol, offers tools that are a useful addition to Foucault’s theory. The ways in which Dutch professionals view problematic Dutch-Caribbean migrants and the interventions they use can be described as different logics.This enables us to recognize the similarities and frictions between different practices.
