POWER SYSTEM OPERATION PLANNING

open access: yes, 1990
Planiranje rada elektroenergetskog sistema podrazumijeva pouzdanu i kvalitetnu opskrbu potrošača električnom energijom uz minimum troškova. Aktivnosti i odluke oko zadovoljenja potrošnje možemo podijeliti u operativno vođenje sistema (on-line funkcije), te funkcije planiranja rada i razvoja EEs-a (off-line funkcije).

Uncertainty in power system planning

open access: yes, 2018
Deterministic transmission planning is based on deterministic assumptions, by planning for a single forecasted set of conditions. The issue of adaptability in transmission and generation expansion planning has become important for planners in order to deal with future uncertainties.
