“…As the main power generators in an MG, RES provide fluctuating power owing to the weather-dependent output, thus making the MG more susceptible to frequency deviations [18]. By leveraging the V2G functionality, EVs can compensate for the RES variability while maximizing the usage of RES for charging.…”

The integration of renewable energy sources (RES) and electric vehicles (EVs) into microgrids (MGs) has significant potential for enhancing energy resilience, addressing environmental concerns, and promoting decentralized energy systems as a global shift towards sustainable energy solutions. Therefore, this survey paper provides a comprehensive discussion on improving MG operation through EV integration. This study evaluates the status of EV integration into MGs, focusing on technological advancements, and emerging trends, while pinpointing key technical challenges and opportunities. Furthermore, this paper examines the pivotal role of EVs in participating in vehicle-to-grid (V2G) services, providing ancillary support to improve MG performance. The importance of a reliable communication infrastructure for information exchange between EV, EV charging stations (EVCSs), and MG has been emphasized for the effective implementation of V2G services. This discussion extends to the contributions of EVs to primary, secondary, and tertiary MG controls. The paper also analyzes the integration of EVs into AC and DC MGs and further proposes configurations for both MG cases. Finally, the paper concludes by providing recommendations for future research to unlock the full potential of EV contributions to MG performance, thereby contributing to the ongoing advancement of sustainable and resilient energy systems. The key findings of this work include solutions for MG voltage and frequency regulation implemented through EV bidirectional converter power flow control, EV charger configurations for integration into AC and DC, EV contributions in improving the MG's operational resilience and adaptability, and the noteworthy challenges arising from V2G implementation in such systems.INDEX TERMS electric vehicle charging, microgrids, renewable energy sources, vehicle-to-grid

“…This technology refers to the systems in which the energy stored in batteries of the electric vehicles can be used as an energy source for houses [35]. For example, during the night, when power consumption is low on the grid, the battery can be charged and the stored energy can be sold to the grid when the energy consumption is high on the grid [36]. The V2H block diagram is shown in Figure 5.…”

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.

“…Therefore, the decentralized V2G control (DVC) method has been addressed in [17]; however, it was only to suppress system frequency fluctuations. One study presented a DVC strategy that can regulate frequencies and synchronize the SOC among the batteries [18]. However, these approaches rely heavily on the aggregator's judgment, which can conflict with that of the PSO.…”

As demand for electric vehicles (EV) grows, interest in vehicle‐to‐grid (V2G) is increasing. Although V2G provides additional flexibility for power systems, it can be an inconvenience for the EV owner and shorten the cycle life of EV batteries. In this paper, we propose a power‐imbalance‐based droop control (PIDC) for V2G, which uses estimated active power imbalance between supply and demand, without any communications or dispatch signal from the automatic generation control (AGC). Unlike the existing frequency droop control, the proposed method controls V2G based on the estimated imbalance. The Imbalance between electricity supply and demand was estimated using the swing equation, frequency deviation, and rate of change of frequency (RoCoF). Conventional frequency droop control has a slow response speed because it only considers the frequency deviation. Using the PIDC, the critical frequency drop was discerned faster and the V2G could react more quickly in critical frequency drop situations. Additionally, battery cycle life was preserved in ordinary frequency fluctuations where V2G is unnecessary. This study used MATLAB R2020a to show the effectiveness and performance of PIDC. The case study results showed that PIDC has a faster response speed and preserves EV battery cycle life compared to frequency droop control.
