    Perspective methods of management of transportand distribution of electric energy in electricnetworks of railways

    The introduction of digital technologies in electrical networks and substations allows the introduction of new technologies and promising methods for managing transportation and distribution of electricity in intelligent electric networks of railways based on multi-agent control. These methods should provide improved performance, adaptive definition of restrictions on the use of electric power equipment, control of mode parameters, partitioning and power flow modes in distribution networks, restoration of power supply after emergency events. A method of adaptive control of transport and distribution of electrical energy in the power supply system of stationary consumers of railways has been developed, based on the hierarchical structure of IEC 61850, taking int o account the coordination of control and local controllers in the data exchange environment, a variable area of responsibility of control controllers multi-agent approach. It presents approaches to managing power flows to reduce energy losses, increase the capacity of transport channels and ensure restoration of the normal mode of the electrical network by reconfiguring it and managing active elements based on graph theory, taking into account the projected hourly load schedule, limiting the demand for power to active consumers and closed mode electrical network operation through controlled sections. The presented simulation results of voltage control in the test circuit showed the feasibility and effectiveness of the proposed approaches.
