Abstract
This paper deals with economical optimization in electric utilities. After a short review which summarizes the optimization activities of the Styrian electric utility STEWEAG, a report is given about an attempt of IBM Austria and STEWEAG to practically implement a short term operation planning system which is universally applicable to electric power systems and district heating systems. Some of the highlights of this optimization model are:
-
•
Complex water reservoir systems including reservoir networks, time delays for the water flow and water contracts to downstream plants
-
•
Coupled energy systems with electric and heating power generation
-
•
Sophisticated interchange contracts taking into account several types of contracts
-
•
New acceleration strategies for solving the optimization problem
The solution of the optimization problem is based upon the mixed integer programming package MPSX and MIP. The optimization kernel is embedded in an extended control program containing a number of new acceleration measures which were necessary to achieve practically acceptable results within reasonable computing times.
