The model of smart grid reliability evaluation/Ismanaus elektros tinklo patikimumo ivertinimo modelis

Smart electricity grids, the essence of development, prospects and trends of electrical grids are described, the model of reliability evaluation is composed in this work. Smart grids enable traditional energy consumers to become active participants in energy markets who can choose when to consume or generate energy in the network. Many countries around the world are promoting the network upgrade, also dealing with energy independence, global warming, energy efficiency and security of supply issues. The system development of smart electrical grid is performed using small distributed generation sources which should be generally evaluated electric network structure and locations change according to recorded speed of isolation expenditure resources and electric network reliability parameters change.

Darbe isnagrineti ismanieji skirstomieji elektros tinklai, ju pletra, esme, perspektyvos bei tendencijos, sudarytas patikimumo jvertinimo modelis. Ismanieji tinklai igalina tradicinius energijos vartotojus tapti aktyviais energetikos rinkos dalyviais, galinciais rinktis, kada vartoti energija, o kada tiekti j tinkla. Daugelis pasaulio saliu skatina tinklu atnaujinima, taip spresdamos energetines nepriklausomybes, globalinio klimato atsilimo, energijos naudojimo efektyvumo ir tiekimo patikimumo klausimus. Ismanaus elektros tinklo sistema pletojama naudojant daug mazqa galia generuojanciu saltiniu, kurie turi buti kompleksiskai ivertinti--registruoti veiksniai, turintys jtakos izoliacijos istekliaus sanaudu kitimo greiciu, taip pat elektros tinklo patikimumo parametru pokyciai, keiciantis elektros tinklo strukturai ir gedimo vietai bei pobudziui elektros tinkle.
