Investigation of the Stability and Frequency Properties of a Generating Complex when Operating on an Autonomous Load

This paper discusses the use of modified permanent magnet synchronous generators in order to improve the controllability of the system and increase the range of operating parameters. A mathematical description of the process of operation of a power supply system built using Smart-grid technology with distributed generation, where each generating cell is a whole generating complex, which must provide the required voltage level and control of the flowing current, is presented. The work of a simulation model of an electric power supply system with a single generating complex, with control functions of an aperiodic type, is considered. The boundaries of the system parameters were established and the key indicators of the transition process and the accuracy of the system operation were evaluated. Recommendations are also formulated for further improvement of the system, which will be aimed at improving the quality indicators of the transition process of nodes and the whole system.
