A smart grid is widely accepted as being a digital, self-healing energy system that delivers electricity or gas from the energy source, including renewable energies, to the points of consumption. It optimizes power delivery and facilitates two-way communication across the grid, enabling end-user energy management, minimizing power disruptions and transporting only the required amount of power. The result is lower cost to the utility and the customer, more reliable power and reduced carbon emissions.
There are a number of reasons why smart grids have attracted so much interest and investment. Enhancing the existing power grids by adding intelligence and digital communications:
Smart grids apply to four key areas in particular:
All these are functionally linked by advanced subsystems, including power conversion modules, communication protocols and energy storage systems.
As a world-leading semiconductor manufacturer, STMicroelectronics has been actively involved in smart-grid technologies, products and applications from the earliest days, and offers a large product portfolio for smart grid needs
