In order to supply their energy requirements, the consumers have changed the paradigm by integrating renewable energy sources to their power grid. Therefore, consumers become prosumers in which they internally generate and consume energy looking for an autonomous operation. This paper proposes an energy management system for coordinating the operation of distributed household prosumers. It was found that better performance is achieved when cooperative operation with other prosumers in a neighborhood environment is achieved. Simulation and experimental results validate the proposed strategy by comparing the performance of islanded prosumers with the operation in cooperative modePeer ReviewedPostprint (author's final draft

    Scenarios for the development of smart grids in the UK: literature review

    Smart grids are expected to play a central role in any transition to a low-carbon energy future, and much research is currently underway on practically every area of smart grids. However, it is evident that even basic aspects such as theoretical and operational definitions, are yet to be agreed upon and be clearly defined. Some aspects (efficient management of supply, including intermittent supply, two-way communication between the producer and user of electricity, use of IT technology to respond to and manage demand, and ensuring safe and secure electricity distribution) are more commonly accepted than others (such as smart meters) in defining what comprises a smart grid. It is clear that smart grid developments enjoy political and financial support both at UK and EU levels, and from the majority of related industries. The reasons for this vary and include the hope that smart grids will facilitate the achievement of carbon reduction targets, create new employment opportunities, and reduce costs relevant to energy generation (fewer power stations) and distribution (fewer losses and better stability). However, smart grid development depends on additional factors, beyond the energy industry. These relate to issues of public acceptability of relevant technologies and associated risks (e.g. data safety, privacy, cyber security), pricing, competition, and regulation; implying the involvement of a wide range of players such as the industry, regulators and consumers. The above constitute a complex set of variables and actors, and interactions between them. In order to best explore ways of possible deployment of smart grids, the use of scenarios is most adequate, as they can incorporate several parameters and variables into a coherent storyline. Scenarios have been previously used in the context of smart grids, but have traditionally focused on factors such as economic growth or policy evolution. Important additional socio-technical aspects of smart grids emerge from the literature review in this report and therefore need to be incorporated in our scenarios. These can be grouped into four (interlinked) main categories: supply side aspects, demand side aspects, policy and regulation, and technical aspects.

    Smart Grid Communications: Overview of Research Challenges, Solutions, and Standardization Activities

    Optimization of energy consumption in future intelligent energy networks (or Smart Grids) will be based on grid-integrated near-real-time communications between various grid elements in generation, transmission, distribution and loads. This paper discusses some of the challenges and opportunities of communications research in the areas of smart grid and smart metering. In particular, we focus on some of the key communications challenges for realizing interoperable and future-proof smart grid/metering networks, smart grid security and privacy, and how some of the existing networking technologies can be applied to energy management. Finally, we also discuss the coordinated standardization efforts in Europe to harmonize communications standards and protocols.Comment: To be published in IEEE Communications Surveys and Tutorial

    Unlocking the potential of the smart metering technology: How can regulation level the playing-field for new services in smart grids?

    By integrating a communications system with the existing power grid, smart grids provide end-to-end connectivity. This enables all entities and components integrated in the electricity supply system to exchange information without knowing the network's structure. New services and applications such as demand response or virtual power plants that will aid to improve and optimize the use of electricity depend on the availability of a smart grid communication network. End-to-end communication networks require that the missing communications gap between consumers' premises and the remaining energy network is bridged by deploying an Advanced Metering Infrastructure (AMI). Given the current liberalized electricity markets' structure incumbent distribution system operators (DSOs) will control the AMI and the meter data. This gives rise to concerns about anti-competitiveness. We argue that leveraging the AMI in a social welfare maximizing way requires non-discriminatory access for all entitled parties to the (1) AMI and the (2) meter data through (3) interoperable standards. We discuss possible regulatory remedies to ensure a level playing-field for innovative services in smart grids and consider implications for research and regulation. --Regulation,Smart Grid,Smart Meter,Antitrust

    ICT and the Environment in Developing Countries: an Overview of Opportunities and Developments

    Get PDF
    Both developed and developing countries face many environmental challenges, including climate change, improving energy efficiency and waste management, addressing air pollution, water quality and scarcity, and loss of natural habitats and biodiversity. Drawing on the existing literature, this paper presents an overview of how the Internet and the ICT and related research communities can help tackle environmental challenges in developing countries. The review focuses on the role of ICTs in climate change mitigation, mitigating other environmental pressures, and climate change adaptation.information and communication technology (ICT), environment, climate change, mitigation, adaptation.
