Vehicle-to-grid : a sociotechnical transition beyond electric mobility
This title defines and charts the barriers and future of vehicle-to-grid technology: a technology that could dramatically reduce emissions, create revenue, and accelerate the adoption of battery electric cars. This technology connects the electric power grid and the transportation system in ways that will enable electric vehicles to store renewable energy and offer valuable services to the electricity grid and its markets. To understand the complex features of this emergent technology, the authors explore the current status and prospect of vehicle-to-grid, and detail the sociotechnical barriers that may impede its fruitful deployment. The book concludes with a policy roadmap to advise decision-makers on how to optimally implement vehicle-to-grid and capture its benefits to society while attempting to avoid the impediments discussed earlier in the book.

Artificial Intelligence Techniques in Smart Grid: A Survey
The smart grid is enabling the collection of massive amounts of high-dimensional and multi-type data about the electric power grid operations, by integrating advanced metering infrastructure, control technologies, and communication technologies. However, the traditional modeling, optimization, and control technologies have many limitations in processing the data; thus, the applications of artificial intelligence (AI) techniques in the smart grid are becoming more apparent. This survey presents a structured review of the existing research into some common AI techniques applied to load forecasting, power grid stability assessment, faults detection, and security problems in the smart grid and power systems. It also provides further research challenges for applying AI technologies to realize truly smart grid systems. Finally, this survey presents opportunities of applying AI to smart grid problems. The paper concludes that the applications of AI techniques can enhance and improve the reliability and resilience of smart grid systems.

Electric power grid resilience with interdependencies between power and communication networks – a review
Because of the development of smart grid technology, today's power grid infrastructures are increasingly and heavily coupled with communication networks for many new and existing power applications. The interdependent relationship between the two systems, in which power control relies on the communication system to deliver control and monitoring messages and network devices require power supplies from the electrical grid, brings challenges in the effort to build a highly resilient integrated infrastructure. In this work, the authors summarise existing research on power grid resilience enhancement with the consideration of the interdependencies between power systems and communication networks. They categorise these works according to stages of resilience enhancement (i.e. failure analysis, vulnerability analysis, failure mitigation, and failure recovery) and methodologies (i.e. analytical solutions, co‐simulation, and empirical studies). They also identify the limitations of existing works and propose potential research opportunities in this demanding area.

A Comprehensive Review on Supraharmonics—The Next Big Power Quality Concern
In recent years, electric power distribution systems have been focusing on power electronic converters. This is due to the integration of smart grids, electric vehicles, and renewable energy sources. As a result of incorporating renewable energy sources, nonlinear loads, and power electronics-based devices, modern electrical power grids are vulnerable to several power quality issues. The use of power electronics converters results in novel supraharmonic emissions, that do not fall within the traditional power quality frequency range. A detailed analysis of supraharmonic emissions is essential as they have a significant impact on the modern electrical grid. This paper starts by discussing the current scenario of electrical power systems and then introduces supraharmonics. The intentional and non-intentional sources of supraharmonics, such as power line communication (PLC), electric vehicle (EV) charging devices, lighting devices, solar and wind energy converters, along with their corresponding emission frequency bands, are also discussed. This paper presents a summary of the measurement methods and standards related to supraharmonic emissions. Finally, various research approaches addressing the reduction of supraharmonic emissions are proposed.

PLUG: A City-Friendly Navigation Model for Electric Vehicles with Power Load Balancing upon the Grid
Worldwide, in many cities, electric vehicles (EVs) have started to spread as a green alternative in transportation. Several well-known automakers have announced their plans to switch to all-electric engines very soon, although for EV drivers, battery range is still a significant concern—especially when driving on long-distance trips and driving EVs with limited battery ranges. Cities have made plans to serve this new form of transportation by providing adequate coverage of EV charging stations in the same way as traditional fuel ones. However, such plans may take a while to be fully deployed and provide the required coverage as appropriate. In addition to the coverage of charging stations, cities need to consider the potential loads over their power grids not only to serve EVs but also to avoid any shortages that may affect existing clients at their various locations. This may take a decade or so. Consequently, in this work, we propose a novel city-friendly navigation model that is oriented to serve EVs in particular. The methodology of this model involves reading real-time power loads at the grid’s transformer nodes and accordingly choosing the routes for EVs to their destinations. Our methodology follows a real-time pricing model to prioritize routes that pass through less-loaded city zones. The model is developed to be self-aware and adaptive to dynamic price changes, and hence, it nominates the shortest least-loaded routes in an automatic and autonomous way. Moreover, the drivers have further routing preferences that are modeled by a preference function with multiple weight variables that vary according to a route’s distance, cost, time, and services. Different from other models in the literature, this is the first work to address the dynamic loads of the electricity grids among various city zones for load-balanced EV routing in an automatic way. This allows for the easy integration of EVs through a city-friendly and anxiety-free navigation model.

Large-scale integration of offshore wind into the Japanese power grid
Offshore wind power attracts intensive attention for decarbonizing power supply in Japan, because Japan has 1600 GW of offshore wind potential in contrast with 300 GW of onshore wind. Offshore wind availability in Japan, however, is significantly constrained by seacoast geography where very deep ocean is close to its coastal line, and eventually, nearly 80% of offshore wind resource is found in an ocean depth deeper than 50 m. Therefore, power system planning should consider both the location of available offshore wind resource and the constraint of power grid integration. This paper analyzes the impact of power grid integration of renewable resources including offshore wind power by considering the detailed location of offshore wind resource and the detailed topology of power grid. The study is performed by an optimal power generation mix model, highlighted by detailed spatial resolution derived from 383 nodes and 472 bulk power transmission lines with hourly temporal resolution through a year. The model identifies the optimal integration of power generation from variable renewables, including offshore wind, given those predetermined capacities. The results imply that, together with extensive solar PV integration, total 33 GW of offshore wind, composed of 20 GW of fixed foundation offshore wind and 13 GW of floating offshore wind could contribute to achieve 50% of renewable penetration in the power supply of Japan, and that scale of offshore wind integration provides a technically feasible picture of large-scale renewable integration in the Japanese power sector.
