Operation planning of power systems
Operation planning of power systems
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
