Multiple objective optimization of hydro-thermal systems using Ritz’s method. (English) Zbl 0948.65059

Using the Ritz method the authors propose an algorithm to minimize an objective function that incorporates the cost of energy losses, the conventional fuel cost and the production of atmospheric emissions such as \(\text{NO}_x\) and \(\text{CO}_2\) caused by the operation of fossil-fueled thermal generation. The formulation includes a general layout of hydro-plants that may form multi-chains of a reservoir network. Time-delays are included and the electric network is considered by using the active power balance equation. The volume of water discharge for each hydro-plant is a given constant amount from the optimization interval.
