With the increasing presence of distributed energy resources in the distribution network, and with the rapid evolution of energy and energy services markets, it becomes essential that smart meters are contributing with complex functionalities. The Horizon 2020 project NOBEL GRID develops an “unbundled” smart meter concept to simultaneously support complex tariffication, real-time data for control functionalities in active low voltage networks, aggregated energy services, power quality assessment, control of production and storage, data security and user privacy as well as enhanced customer awareness. The project will develop and test innovative technologies in five European demonstrators: Spain, Italy, United Kingdom, Belgium and Greece.
Major utility National Grid has recently completed the full deployment of a smart grid pilot delivering a multi-tier communications network infrastructure to enable the end-to-end smart grid pilot objectives. The authors share the utility's approach and some initial experiences in delivering this complex solution including some of the early lessons learned and experiences with the technologies utilized.
Microgrids with local controllers and a variety of generation units (tri-generation, renewables), storage systems (electrical, thermal) and loads (residential buildings, offices, electrical vehicles, etc.) represent a challenge for the development of business models, strategies and approaches for local optimal scheduling, and demand response programs, and can contribute to delivering services to distribution system operators in a smart city.
Traditional methods of understanding grid interactions are increasingly insufficient for the 21st Century grid. The discipline of grid architecture treats the grid as a Network of Structures with ultra-large scale complexity. This provides a means to help all stakeholders understand the impact of changes across the grid infrastructure, controls, industry structure, communications, markets, and more.
