Use of the 450 MHz band for power distributors

The paper deals with the possibilities of using the 450 MHz radio band for mutual communication and duplex transmission of data between the elements of the distribution network in the concept of Smart Metering and later also the Smart Grids. The introduction of these concepts should help to balance the generation and consumption of electricity in the distribution system. Increasing share of intermittent sources of electricity using wind and sun on the installed capacity of power plants in the power system changes the fundamental paradigm of the economy of the power engineering. Instead of adjustment (control) instantaneous power sources according to the current electricity consumption started operative adjustment of consumption according to the instantaneous power of intermittent sources. It is the aim of the concept of Smart Grids where the price motivated consumers to adapt to intermittent production without sacrificing his comfort. In order to ensure the transfer of information not only from the control center to the consumers but also mainly from the consumers to the control center (duplex), it is necessary to ensure high-quality information connections.
