  14. 14. Matteo Zatti, LEAP - 30.04.2019 Il Progetto EFFICITY 14 Conclusioni • È stata sviluppata una metodologia per l’ottimizzazione stocastica del design di sistemi multi- energia; • Può essere usata per valutare politiche incentivanti, tassazione CO2 e varie scelte strategiche; • Quando si considera un distretto pro-attivo e/o a emissioni zero, l’incertezza associata alle previsioni diviene significativa (se non considerata fa aumentare notevolmente gli sbilanciamenti e quindi i costi operativi, interessante in ottica UVAM); • È stata sviluppata una metodologia per l’ottimizzazione stocastica e l’ottimizzazione robusta (non discussa in questa presentazione) della gestione di sistemi multi-energia; • Lo scheduling stocastico costituisce un input affidabile per i sistemi di gestione real-time di sistemi multi-energia.
