Kaunas hydropower system management

摘要

The floods occurring in Europe recently confirm that some natural phenomena are unexpected and very difficult to control. Despite this, the proper subjects of infrastructure and scientific institutes try to find common decisions to minimize flood risk levels as much as possible. Currently the European Commission is reviewing legal documents and in the near future EU countries will have to implement flood management directives. This paper presents a developed mathematical model of flood control which was applied for Kaunas hydropower system. The model consists of two parts: water level calculation algorithms, which were developed using only operational system data, and a risk based water level control model based on an optimization algorithm and integrated risk parameters. The model helps to accept risk based decisions during the flood period and offers alternatives of discharge and water level control near the dam. As a result the flood control characteristics and extreme scenarios are presented.
