Abstract :
This paper addresses a multiperiod optimal power flow, properly modeling the start-up and shut-down of thermal units, the transmission network in terms of line capacity limits and line losses, and the constraints of hydroelectric plants integrated in river systems. The generalized Benders decomposition is used to solve this large-scale multiperiod problem. Spot prices are obtained as a byproduct of the decomposition procedure. A realistic case study based on the electric energy system of mainland Spain is analyzed and the results obtained are reported
