| Abstrakt v dalším jazyce: | The Electric Power System (ES) must address two unique requirements - the need to maintain balance between generation and load, at the required time and with the required quality, and the need to adjust generation (or load) to manage power flows through individual transmission facilities. These requirements are performed mainly by synchronous generators (SG) which use for static transmission of the network the inertia of the power sources resulting from the direct electromechanical connections between the synchronous generators and the network. The Renewable Energy Sources (RES) utilization for power system supplying, notably inverter-connected electric generators that do not provide rotational inertia is effectively displacing conventional generators and their rotating machinery. This has implications for frequency dynamics and power system stability and operation. Second finding is that frequency dynamics are faster in power systems with low rotational inertia. This unwanted phenomenon preventing can be making by artificial inertia use with appliance and methods which are able to ensure ancillary services for power balance keeping in the electric networks. The use of rotary flywheels seems promising. |
