The distributions of electrical systems are in constant evolution. Constantly, new users and infrastructures are emerging, which must be supplied with energy. In addition, existing networks are growing larger and becoming stronger, in comparison to their consumer that is why they have to be renovated. Furthermore, constantly seeking ways to optimize systems and carrying out a complete or partial design. With the advent of generational power from renewable energy sources, the network’s challenge is their integration. They are gradually beginning to look at the Smart Grid concept, as an unprecedented opportunity, for network management with high reliability, accessibility and efficiency. This technology is based on the classic approach, from which they are trying to see what different and new that could be added in Smart Grid technology.
Electricity has the ability, to easily and with high efficiency, to transform into other types of energy. Thanks to this property, it has become widespread in all spheres of life, social life and production life as well. Transmission networks and distribution are the link between electricity producers and consumers. They are the ones who have to ensure the quality of energy and lack of interruptions.
In the era of centralized power generation, transmission and distribution systems, had followed the classical approach, in order to design and build. With the advent of small decentralized power from renewable energy, the scheme is beginning to change and Smart Grid technology is becoming more and more talked about technology. The emergence of intelligent networks is made possible with the development of electric technologies, and computer and communication equipment. Benefits that are expected to bring much. Besides quality and reliable power supply, they can offer higher efficiency of energy use, faster recovery after interruptions, reduce operations and maintenance funds for the network and thus ultimately lower costs for consumers.
