Comparative review of long-term energy storage technologies for renewable energy systems/Ilgalaikio energijos kaupimo technologiju taikymo atsinaujinancioms energijos sistemoms lyginamoji analize

Sustainability of electric power systems will involve very large use of renewable energy sources for power production. Wind power is one of the cleanest and safest of all the renewable methods of generating electricity. However, wind power fluctuations have adverse impacts on power quality, such as local voltage and system frequency. Energy storage devices will be needed at different locations in the power system, to store the surplus of power from renewable sources for later use during non-generation time periods or low power generation time periods. This paper will give an overview of different storage technologies. Ill. 10, bibl. 20, tabl. 3 (in English; abstracts in English and Lithuanian). Energetikos sistemu issilaikomumui uztikrinti gaminant energija reikes naudoti daug atsinaujinanciu energijos saltiniu. Vejo energija yra vienas is svariausiu ir saugiausiu atsinaujinanciu elektros energijos saltiniu. Taciau vejo energijos fliuktuacijos turi neigiama poveiki energijos kokybei (itampai ir sistemos dazniui). Energijos kaupimo itaisai bus reikalingi skirtingose energijos sistemos vietose perteklinei energijai is atsinaujinanciu saltiniu kaupti ir veliau jai panaudoti. Pateikiama skirtingu kaupimo technologiju apzvalga. Il. 10, bibl. 20, lent. 3 (anglu kalba; santraukos anglu ir lietuviu k.).
