3.7.3 Hydro Power Library
The Hydro Power Library is a new library that provides a framework for modeling and
simulation of hydropower plant operation. The library components enable performance
analysis and optimization of the operation of hydropower plants. It offers an excellent
environment for testing new control strategies and tuning plant controllers for optimal
performance. Optimization of the operation of power plants with multiple reservoirs and
multiple turbines in order to maximize the overall efficiency is in important application.
Accurate simulation results can have a significant effect on the efficiency and thereby the
profitability of the operation.
The Hydro Power Library is suitable for simulation of transient operation such as load
rejection to verify that the control system can handle these situations. It can also be used for
studying various control strategies to cope with the rapid load changes that become more
frequent as other renewable, less controllable, sources of energy are increasingly used for
power generation. It is also targeted for use in design of new hydropower plants. Planning of
commissioning tests and procedures can be set-up, thereby reducing the risk of unexpected
events and minimizing costly tests done on the actual plant.
