Smart gridsNew policy goals are largely shaping current transformations in electricity sector in Europe. Nowadays power systems, especially the electrical distribution grids are accommodating different renewable technologies, grid users resulting into increasing the requirements for stable, safe and efficient power system operation as well as new energy services. In order to achieve the European and national energy policy objectives, a new global approach in the generation, transmission, distribution, metering and consumption of electricity is necessary.
Smart grids are a key component of the European Strategy towards to a low – carbon energy. Smart grids have an essential role in the process of transforming the functionality of the present electricity transmission and distribution grids so that they are able to provide a user-oriented service, supporting the achievement of the 20/20/20 targets and guaranteeing high security, quality and economic efficiency of electricity supply in a market environment. Development of smart grids is facilitated by the wide-scale deployment of electricity smart metering, as envisaged in 3rd Energy Package.
A Smart Grid is an electricity network that can cost efficiently integrate the behaviour and actions of all users connected to it – generators, consumers and those that do both – in order to ensure economically efficient, sustainable power system with low losses and high levels of quality and security of supply and safety. Though elements of smartness also exist in many parts of existing grids, the difference between a today’s grid and a smart grid of the future is mainly the grid’s capability to handle more complexity than today in an efficient and effective way. A Smart Grid employs innovative products and services together with intelligent monitoring, control, communication, and self-healing technologies.
