Risk and Reliability Analysis of Open Reservoir Water Shortages Using Optimization

Abstract

The goal of this paper was to describe how to find optimal relations between water shortage and hydropower energy based on Risk and Reliability methods. Reservoir simulation model including water losses as well as risk (reliability) model of water demand has been built up. Using NSGA II optimization method the optimization of reservoir operation has been done. For problem solving was used Multi-Objective Optimization. This approach has been applied to a real-life water reservoir called Vir 1 in the Czech Republic. Results were presented in the form of Pareto curves and data sets of reservoir outflows.The goal of this paper was to describe how to find optimal relations between water shortage and hydropower energy based on Risk and Reliability methods.
