ANY ELECTRIC ENERGY SYSTEM CONSISTS OF THREE MAIN STAGES: 1. The stage of generating electric energy, based on different methods of transforming different kinds of energy (mechanical, heat, etc.) into electric energy. For example: • A source of mechanical energy can be the power of water (hydropower stations, pump storage plants, tidal energy station). • Thermal sources of energy can be thermoelectric plants (TEP), nuclear power station (NPS). • Alternative sources of energy can be wind power, solar energy, etc. The main factor for all methods is the stability of their performance. 2. The stage of transfer and distribution of electric energy is determined by the practicality of transferring it over large distances at the maximum high level of voltage. It will result in reducing current values in transmission networks, and, as a consequence, reducing losses during transmission of electric energy. 3.
