Optimizing Steady Operating Points of Several Generating Unit Systems for Transient Applications

摘要

Pump storage power plant operation demands for wide operating ranges with quick load steps due to compensation of volatile generated wind and photovoltaic energy. This results in off-design operation which requires knowledge about the optimum operating point for all power ratings required by the electrical grid. In this paper a Mixed Integer Non Linear Programming solver including heuristics is applied to find best steady efficiency points of complex generating systems for different required power outputs. Beside high efficiency at steady operation a rapid and smooth operating point change is the second main task of such plants. Therefore, in the second part, the optimization results are used for a transient simulation of a sample operating point change.
