This dissertation presents a genetic algorithm-based method for calculating
of power system dynamic equivalents aiming to represent parts of a power system for
transient stability analysis. The dynamic equivalent calculation is obtained through
carrying out the parameter identification of synchronous generators located on frontier
buses, linking the external and the studied subsystem. An index is used to assess the
proximity between simulations carried out using the full and the reduced model
following the large disturbances emerged in the studied subsystem. Different operating
conditions are taken into account. The simulations were conducted using the softwares
GAOT “The Genetic Algorithm Optimization Toolbox”,, ANAREDE and ANATEM.
This method is tested on a Kundur’s two-area test system and on a Brazilian
Interconnect Power System (BIPS). Test results validate the efficacy of the developed
methodology in calculating the robust dynamic equivalents. |
