Three utilization patterns of the renovated Moste hydro power plant on an electricity market of power and ancillary services

摘要

In addition to electricity, most hydro power plants can offer also the ancillary services: secondary and tertiary control reserve. On emerging electricity markets the need for these additional services is becoming more and more important, recognised and also paid. However, for each plant, there is some interdependence among those options. The same plant cannot provide maximal peaking electricity, maximal secondary control reserve as well as maximal tertiary control reserve at the same time. The generation capabilities of the plant must thus be partitioned properly among those options so as to achieve some overall goal (e.g. the maximum of revenue, etc.). This article briefly presents those options for the renovated Moste cascade on the upper Sava river near Bled in Slovenia. A small but effective mixed integer linear programme has been used.
