“…At the same time, the report questions the storage capacity of E-vehicle batteries, because this is financially less attractive than back-up capacity from the grid. Veldman and Verzijlbergh [36] argue for the use of electric vehicles (EV) as a balancing medium for the network with new tariff structures. She uses the example of an EV owner who pays more for rapidly charging his car any time he wants compared to an EV owner leaving the timing and speed of charging to the DSO or supply company.…”

Prosumption and the distribution and supply of electricity

Background: Increasing numbers of households install renewable energy production systems like photovoltaic panels thereby contributing to a more sustainable energy system. Other developments, like in-home storage or peer-to-peer exchange within a neighbourhood, also contribute to the transition. This paper explores the emerging rise of these prosumers of electricity and its implications, in particular for grid management and electricity supply in the Netherlands. Methods: With the help of an agent-based model, we illustrate the evolution of prosumption in a small Dutch-oriented residential community in five scenarios. The second part of the paper discusses the implications of the modelled rise in prosumption.Results: Depending on the number of prosumers, combined with storage and peer-to-peer supply, we found a share of prosumption in this local community of about 28-30 %. The community will require less electricity from the central power plants. These model results also indicate that the management of the local network will become more important if more households become prosumers in combination with storage and peer-to-peer supply. Conclusions: These trends affect current business models of DSOs and electricity production and supply companies. The latter are facing a loss of turnover which needs to be compensated by developing alternative business models. And, DSOs have to deal with the new needs on the local grid which also require an adaptation of their business models. Developing business models in cooperation with local energy communities could be an attractive alternative to explore.

“…The number of railway vehicles undergoing battery charging and discharging during each time period is calculated using (4) and (5). Further, the electricity prices based on T2G are calculated using (6). The first term of (6) is intended to calculate the demand charge based on T2G, and the second term is designed to calculate the energy charge for each time period.…”

Smart transportation technologies are being rapidly developed for enhancing the smart grid establishment. Such technologies are mostly focused on electric vehicles. However, the electric railroad has advantages in various aspects such as facility construction and utilization over an electric vehicle. Therefore, in this paper, we introduce the train-to-grid system using the electric railroads for the smart grid, and propose a reduction method for the electricity prices. The proposed method obtains actual data from the currently operating railroad systems. Furthermore, the number of trains for charging and discharging batteries is decided by using the time-of-use price and the number of railroad operations. The electricity prices are then determined by the energy consumption calculated using the number of trains used for charging and discharging and the capacity of the energy storage system in the trains. The proposed method is simulated using real data, and its superiority is verified by comparing its electric prices with the conventional electricity prices.

“…If the power generation of the system is dominated by coal-fired power plants, the emission advantage of EVs is not obvious [4]. Secondly, more investment is required in order to expand the capacities of generation, transmission, and distribution, due to the increasing charging requirements of EVs [5,6]. As a kind of renewable and clean energy, PV power can be produced in any part of an urban area.…”

Abstract:The Photovoltaic-assisted Charging Station (PVCS) is regarded as one of the most promising charging facilities for future electric vehicle (EV) energy supplementation. In this paper, the operation mode and profitability of a commercialized PVCS are analyzed under the energy policy of China. In order to evaluate the long-term effectiveness of using the PVCS to provide guidance for the investors of the stations, a set of evaluation indexes is introduced, including the quality of service, the environmental and economic benefits, and the impacts on the grid. Furthermore, an easily-achieved charging strategy which considers the quality of service and the self-consumption of PV energy is proposed. Finally, an effectiveness evaluation for different operational scenarios of the PVCS is completed, based on the actual statistical data. The simulation and evaluation results indicate that the PVCS has the potential to produce satisfactory environmental/economic benefits and to reduce the impacts and dependence of an EV's charging load on the grid.
