“…In [30], the authors consider up-down regulation and spinning and non-spinning reserve services in the frequency control category. The classification proposed in [31] includes congestion prevention and loss reduction in the category of loading services, while voltage magnitude regulation and imbalance reduction are considered in the voltage services category. Similarly, in [18], peak load reduction and power loss services are considered in the congestion prevention category.…”

“…In this way, managing the charging/discharging control of EVs as a service for supporting the distribution grid becomes a new paradigm that requires an appropriate regulatory framework that endorses the EV service provision for DSOs [31]. By having a clear concept on it, the current strategies and methods developed to provide EV-DSS can be improved, or new ones can even be proposed to align with the current requirements for realistic implementations.…”

Trend-setting countries have promoted or even employed an increased number of electric vehicles (EVs) and other distributed energy resources (DERs) in their power systems. This development has triggered new and increasing challenges in the distribution system planning and operation, whereby distribution systems must adapt to the increased share of DERs. However, EVs may also offer new opportunities and can be used to support the grid by providing several local and global powerand energy-based services. This paper presents a review and classification of the services potentially available from EVs for distribution systems, referred to as EV distribution system services (EV-DSS). A detailed description of recent services and approaches is given, and an assessment of the maturity of EV-DSS is provided. Moreover, challenges and prospects for future research are identified, considering key topics, such as the design of the market framework, economic assessment, battery degradation, and the impacts of the transmission system operator service provision by EVs on distribution networks. Thus, this work offers a tool for stakeholders concerning services available from EVs and provides a broad literature framework that can be used as a base for further investigations. It is aligned with the current requirements to move toward realistic implementations of EV-DSS.

The connection of electric vehicles to distribution networks has been an emerging issue of paramount importance for power systems. On one hand, it provides new opportunities for climate change mitigation, if electric energy used for charging is produced from zero emission sources. On the other hand, it stresses networks that are now required to accommodate, in addition to the loads and production from distributed generation they are initially designed for, loads from electric vehicles charging. In order to achieve maximum use of the grid without substantially affecting its performance, these issues have to be addressed in a coordinated manner, which requires adequate knowledge of the system under consideration. It is advantageous that electric vehicle charging can be controlled to a certain degree. This research provides better understanding of real distribution networks' operation, proposing specific operational points through minimizing electric vehicle charging effects. The probabilistic Monte Carlo method on high performance computers is used for the calculations.Energies 2018, 11, 2400 2 of 15 However, stochastic methods, and especially Monte Carlo [11], is computationally demanding even for today's standards; hence, specific operational points are developed in this study for a specific network [12].Electric vehicles charging would also require a grid expansion design factor [13]. Current research on electric vehicles, as far as the distribution network is concerned, gives emphasis to probabilistic methods in order to predict charging patterns, and predict the expected charging behavior. This also affects the connection points for distributed generations, that could be optimally different if connected points are based on probabilistic methods, taking into consideration their intermittency [14]. As far as electric vehicles are concerned, the first step is to characterize their charging demand [15]. In some cases, the system is simulated as a whole, and the operational benefits are optimized based on electric charging owners' behavior [16]. Alternatively, they are connected in a way that relieves distribution system constraints [17]. Active distribution network management could be done by aggregating electric vehicle behavior in a probabilistic manner [12]. Probabilistic studies have also shown good correlation between electric vehicles and renewables [18]. In this research, electric vehicle and load aggregation is performed on the level of a secondary distribution system, at the point of medium voltage (MV)/low voltage (LV) connection, and it is fully controlled.Having mentioned the above, several studies have researched the emerging phenomenon of electric vehicles. All of them are consumer oriented, giving emphasis to electric vehicles per se, and showing minimal consideration for the electricity grid. On the other hand, the research presented in the current paper is electric grid oriented. It is focused in the procedure of creating optimal electric grid operation points for electric vehicle charging for a r...

Being a small well‐organized city state, Singapore appears to be an ideal place to establish a fully electric road transport system. To analyze the challenges and potential of electric mobility (or “electromobility”), TUMCREATE Ltd., a company funded by Singapore's National Research Foundation, was launched in 2011 as “Centre for Electromobility in Megacities”. During the first five years, the research at TUMCREATE covered everything “from the molecule to the megacity”, that is, from fundamental research on new materials for energy storage systems to battery cells, battery packs, vehicle technology, in‐vehicle electronics to road infrastructure and the power system. One outcome was a prototype for an electric taxi for tropical megacities called EVA with a battery capacity of 50 kWh and fast charging capability of 160 kW. This paper presents a review of past and ongoing activities in the field of integration of electromobility into Singapore's power system. The focus of this publication lies on charging of electric vehicles (EVs). Results show that the integration of EVs into the power system is feasible, leads to lower emissions, and can even offer new services and support integration of renewable energies.
