TL;DR: A dynamic complex network model of V2G mobile energy networks is presented, considering the fact that EVs travel across multiple districts, and hence EVs can be acting as energy transporters among different districts and shows that EVs mobility of symmetrical EV fleet is able to achieve synchronous stability of network and balance the power demandamong different districts.
Abstract: Vehicle-to-grid (V2G) technology enables bidirectional energy flow between electric vehicles (EVs) and power grid, which provides flexible demand response management (DRM) for the reliability of smart grid. EV mobility is a unique and inherent feature of the V2G system. However, the inter-relationship between EV mobility and DRM is not obvious. In this paper, we focus on the exploration of EV mobility to impact DRM in V2G systems in smart grid. We first present a dynamic complex network model of V2G mobile energy networks, considering the fact that EVs travel across multiple districts, and hence EVs can be acting as energy transporters among different districts. We formulate the districts’ DRM dynamics, which is coupled with each other through EV fleets. In addition, a complex network synchronization method is proposed to analyze the dynamic behavior in V2G mobile energy networks. Numerical results show that EVs mobility of symmetrical EV fleet is able to achieve synchronous stability of network and balance the power demand among different districts. This observation is also validated by simulation with real world data.

TL;DR: A new one-time signature scheme which can reduce the storage cost by a factor of 8 and reduce the signature size by 40% compared with existing schemes is proposed and is more appropriate for smart grid applications where the receivers have limited storage or where data communication is frequent and short.
Abstract: Multicast has been envisioned to be useful in many smart grid applications such as demand-response, wide area protection , in-substation protection and various operation and control. Since the multicast messages are related to critical control, authentication is necessary to prevent message forgery attacks. In this paper, we first identify the requirements of multicast communication and multicast authentication in the smart grid. Based on these requirements, we find that one-time signature based multicast authentication is a promising solution, due to its short authentication delay and low computation cost. However, existing one-time signatures are not designed for the smart grid and they may have high storage and bandwidth overhead. To address this problem, we propose a new one-time signature scheme which can reduce the storage cost by a factor of 8 and reduce the signature size by 40% compared with existing schemes. Thus, our scheme is more appropriate for smart grid applications where the receivers have limited storage (e.g., home appliances and field devices) or where data communication is frequent and short (e.g., phasor data). These gains are at the cost of increased computations in signature generation and/or verification and fortunately our scheme can flexibly allocate the computations between the sender and receiver based on their computing resources. We formulate the computation allocation as a nonlinear integer programming problem to minimize the signing cost under a certain verification cost and propose a heuristic solution to solve it.

TL;DR: In this paper, the U.S. Department of Energy (DOE) has placed an added emphasis on R&D to enhance resilience to climate change and extreme weather, adopting a public/private partnership approach to join with key stakeholders in developing and implementing a resilient grid R&DOE plan.
Abstract: ELECTRIC DISTRIBUTION GRID RESEARCH AND DEVELOPment (RD however, this focus has primarily been outside the realm of severe climate events. Due to the increasing frequency and intensity of weather-caused grid outages in recent years, the U.S. Department of Energy (DOE) has placed an added emphasis on R&D to enhance resilience to climate change and extreme weather. To forge a focused national R&D effort on grid resilience, the DOE is adopting a public/private partnership approach to join with key stakeholders in developing and implementing a resilient grid R&D plan. This article presents the plan development process and the R&D need areas identified for pursuit.

TL;DR: An IPbased decentralized and data-centric information infrastructure that can reliably, securely, and cost-effectively support the operation and innovative applications of the next generation grid.
Abstract: In recent years the power grid has been undergoing transformative changes due to the greater penetration of renewable energy sources and increased focus on power demand shaping. These innovative transformations on the grid require a flexible IP-based communication grid that is reliable and secure. In this article we describe an IPbased decentralized and data-centric information infrastructure that can reliably, securely, and cost-effectively support the operation and innovative applications of the next generation grid. The proposed infrastructure differs from a typical distributed system since it addresses the specific requirements of power applications such as security, distributed data sources, latency sensitive data transactions and real time event updates. The work presented here paves the way for a future data-centric power network infrastructure.
