“…In case of transferring from an electrical vehicle to a building, it must be between 10 and 15 kW. Or, if the energy is transferring from an electrical vehicle to another electrical vehicles, this value must be between 15 and 30 kW [39]. These standards are very important for energy efficiency, continuity, and reliability [40].…”

Electric vehicles are the latest form of technology developed to create an environmentally friendly transportation sector and act as an additional energy source to minimize the demand on the grid. This comprehensive research review presents the vehicle-to-grid (V2G) and the vehicle-to-home (V2H) technologies, along with their structures, components, power electronic topologies, communication standards, socket structure, and charging methods. In addition, the charging topologies in V2G and V2H are given in detail. This study is planned as a useful guide for future studies that can be achieved in that it compares the results obtained and analyzes the studies in the literature, finding the advantages and disadvantages of charging topologies in V2G and V2H.

“…Due to the increasing attention paid to environmental problems such as CO2 emissions and air pollution, as well as the dependence on fossil fuels, both governments and automotive industry head towards a widespread diffusion of plug-in electric vehicles (EVs). However, a high degree of EV penetration could pose serious problems to medium voltage (MV) and low voltage (LV) distribution networks related to the power quality [1,2]. A massive EV charging could increase power losses, overload MV and/or LV feeders and cause voltage constraint violations along the feeders [3].…”

The paper proposes a methodological approach to manage the electric vehicles recharging in an isolated power system characterized by low short circuit power. Focusing on harmonic disturbances, current harmonics injected in the network depend on the specific EV power converter. The model carried out allows for the evaluation of harmonic disturbances under variable conditions for non-linear loads and their harmonic spectra. The methodology allows estimating both current and voltage total harmonic distortion (THDV, THDI) at the point of common coupling (PCC). An algorithm able to manage and control the EV charging in a parking area has been developed in order to keep the THDV under a threshold limit. Index Terms--electric vehicles, control algorithm, harmonic disturbances modeling, islanded networks, power system harmonics.I.

“…In recent years power quality issues like harmonics and flicker have become more important [15], resulting in additional moise in the frequency signal. On top of that, the expansion of wireless communication networks results in higher interference with the power grid and higher noise levels.…”

There is an increasing interest in exploiting the flexibility of loads to provide ancillary services to the grid. In this paper we study how response delays and lockout constraints affect the controllability of an aggregation of refrigerators offering primary frequency control (PFC). First we examine the effect of delays in PFC provision from an aggregation of refrigerators, using a two-area power system. We propose a framework to systematically address frequency measurement and response delays and we determine safe values for the total delays via simulations. We introduce a controllability index to evaluate PFC provision under lockout constraints of refrigerators compressors. We conduct extensive simulations to study the effects of measurement delay, ramping times, lockout durations and rotational inertia on the controllability of the aggregation and system stability. Finally, we discuss solutions for offering reliable PFC provision from thermostatically controlled loads under lockout constraints and we propose a supervisory control to enhance the robustness of their controllers.
