Smart grids micro grids smarty cities8/26/2023 Private, corporate, and public charging stations for electric cars will have to become smart too, since they will have to communicate with each other as well as with different backend systems, e.g. Bus depots, for example, will best be designed as intelligent microgrids, thus becoming smart infrastructures. The whole energy supply and demand will need to be considered, encompassing renewable generation, storage integration, and charging potential on location. Nevertheless, to make eMobility work, simply putting charging points in place will not be sufficient. This allows, for example, to make best use of peak production of PV plants at noon. With smart grids and smart charging technology, however, this alleged downside can be turned into an advantage: Already today, smart charging enables to manage the optimal time for charging electric vehicles. This trend goes with a rising demand for electricity, putting additional strain on the grid. As other cities and megacities are already following or will follow suit, depots with overnight-charging infrastructure for some hundreds of buses or commercial vehicles will become a common feature of future cities, not to mention the rising number of privately owned electric cars. The metropolis of Shenzhen, China for example pulled off in electrifying its 16,000-strong bus fleet. The electrification of mobility not only is considered as a key to decarbonization, it also promises to mitigate two other major issues of big cities: noise and air pollution.Īlready, the first large-scale electromobility projects have been successfully implemented. When buildings and cars talk about electricity The project demonstrates how existing, residential heat infrastructure can be integrated into a smart grid – and that it can play an active role in providing more flexibility to the grid, which will be a prerequisite for the transition into a greener future. In the project, NB Power successfully shifted heating load peaks by managing smart thermostats and water heaters. This has been applied, for example, in a pilot project by Canadian power utility together with Siemens, which explored the potential of the smart use of electric power infrastructures in the residential sector. This is only possible when conventional power grids are combined with data networks, or, in other words, when they become smart. In the smart city of the future, buildings will become an active part of the energy system. This allows holistic control of all aspects of the infrastructure. The information it generates is used for integrated site management, including energy, security, waste management, irrigation as well as indoor and outdoor air quality and eMobility charging. In an area of 4.38 square kilometers, data from more than 130 buildings and over 200’000 data points are being collected by a cloud-based IoT operating system. How so? One of the most impressive examples to date is the Expo 2020 Dubai project. Smart cities now seek to combine the data from different sectors and to make it accessible in the cloud, thus creating ecosystems that will bring digitalization in cities to the next level and allowing new ways of making use of the data. Even in the age of ICT, data has been collected and stored in silos. What is more, smart technology has the potential to make cities more livable, resilient and secure.įor a long time, different infrastructure sectors have been managed separately. In a world more and more powered by renewables, cities’ infrastructure must become smart and interconnected not only to further decrease energy consumption and reduce carbon emissions, but also to provide more flexibility to the electricity grid. However, this will not be enough to make decarbonization work. They are extremely good at optimizing consumption per capita due to their high population density. From an energy point of view, cities are major consumers of resources.
