Some problems of backbone and distribution networks of Russia are considered. The “bottlenecks” are shown with specific references and suggestions for their elimination are given. It is pointed out that the main problems are related to distribution electric grids, which are the technological basis for the emerging retail electricity market.

The paper considers the organization of maintaining single time in automated systems of energy facilities. These facilities provide technological events recording as well as processing and analyzing of incoming energy data for electric power distribution management and commercial and technical accounting. Such facilities as step down substations distributed in the region and dispatching centers of layered control system are among important and sophisticated elements of any utility. The features of time synchronization in heterogeneous systems, ways of single time distribution over the communication channels and collection of information about connection between time and events occurring in technological equipment are considered.

The paper presents research, design and development works performed with the aim of increasing efficiency of energy saving and power quality in 0.38 kV electrical networks with asymmetrical load. “Electric power losses” computer program and method for calculating power losses, electric power losses and voltage and current unbalance indexes in 0.38 kV electrical networks with distributed asymmetrical load have been developed. Invention patents have been received for all afore-mentioned developments. All developments are innovative.

The conceptual issues of the scheme for 20 kV electrical networks development in Moscow are considered. The design concepts of existing network as well as parameters, state and current load of the main equipment are determined. Integrated characteristics are calculated. Two options of load growth estimates for different scenarios of economic growth are developed. Also, an analysis of forecasts accuracy for previous development schemes is conducted. Measures for power losses reducing in the electrical network are proposed. The volume of necessary financing is determined until 2030.

20 kV overhead systems with low resistance neutral grounding are considered (such systems are new among home-grown technologies). The justification and calculation of necessary single-phase ground current for providing electrical network reliability and efficiency are presented. The influence of various factors on the target current value is shown (the target current has different values for cable and overhead systems). Recommendations on the structure and parameters of 20 kV electrical network are given.

In recent years, a significant number of articles have been published on the negative impact of XLPE cables on transfer potentials. Also, the transfer of medium voltage distribution networks on the low-resistance grounding has been the subject of discussion. In view of the fact that low-resistance grounding (as compared to insulated/ inductive neutral grounding) as well as XLPE cables (instead of cables with paper-oil insulation) are considered to be effective modern solutions for urban cable distribution networks, a study for developing recommendations to calculate the transfer potentials in a low voltage electrical network was conducted, and analysis of measures to prevent the transfer of hazardous potentials in the network was executed.
