Šiame darbe atliekami elektros energijos kainų analizė ir modeliavimas. Elektros kainų kitimui ir tokioms jų charakteringoms savybėms, kaip sezoniškumas, vidurkio reversija, darbo dienų, savaitgalio ir švenčių efektas, kintamumo klasterizacija, aprašyti taikomi SARIMA-TGARCH ir SARFIMA-TGARCH modeliai. Tyrimui naudojami kasvalandiniai Prancūzijos elektros energijos biržos kainų stebėjimai. Darbą sudaro dvi dalys – bendroji (teorinė) ir tiriamoji dalys. Pirmoje dalyje apžvelgiama literatūra bei aptariami teoriniai modelių aspektai: aprašomi ilgos atminties modeliai. Antroje dalyje pristatomi modelių empiriniai rezultatai: SARIMA-TGARCH ir SARFIMA-TGARCH modelių taikymas ir adekvatumo tikrinimas. / In this paper an econometric modelling and forecasting of electricity spot prices is presented. The aim of this work is to examine SARIMA-TGARCH and SARFIMA-TGARCH models for describing volatility of electricity spot prices and their characteristics such as season, mean reversion, volatility cauterization, and effects of workdays, weekends or holidays. The data of France electricity stock prices are used for analysis. This paper contains two parts – theoretical and empirical. In the first part the short review of literature is presented. Moreover, the theoretical aspects of long memory models are discussed. In the following part the empirical results are presented: application and adequacy examination of SARIMA-TGARCH and SARFIMA-TGARCH models.
