Power Loss in Smart Grids

SMART GRID is a system of transmission of electricity from the producer to the consumer, monitoring and distributing the flow of electricity to achieve the highest energy efficiency. The basis of the new generation network is the use in the general power system of numerous various distributed energy sources, which include low-power stations and installations that operate, including renewable energy sources. Using distributed energy sources makes it possible to reduce power losses during power transmission. In today's market conditions, in financial calculations between the energy system and consumers, it is important to analyze the energy balance, which includes the technological consumption of electricity for its transmission. Therefore, the issues of determining electricity losses are very relevant. However, with introducing information-measuring systems, the information security of calculations increases, so it became possible to take into account additional factors while calculating losses, determining the structure of losses in the entire transmission and distribution system of electricity, and identifying the place of increased losses. Gathered information makes it possible to take measures for the rational reduction of losses. Energy storage systems are rapidly developing a class of high-tech devices that open new opportunities in the energy power industry. They make electricity stored and portable, eliminating the need for strict simultaneity of its generation and consumption the fundamental constraint of power balance, which was a key factor to make a modern architecture of energy systems operating around the world. Electric power storages are fundamentally new element of their architecture, complementing the objects of generation, transmission, and consumption and opening wide opportunities for the effective realization of the potential of new types of distributed generation. The new active consumers will be using already commissioned and new energy capacities and operate energy systems in general.
