Extensions of large-scale power system simulation algorithms to include the effects of dispersed generation

Preliminary simulation results of power systems using “complete” generator/exciter/governor models for synchronous machine generator systems are given in this paper. Traditional and advanced models for the electrical and mechanical subsystems of a generating unit are provided and discussed independently, and simulation results for a simple system are provided to verify the results. One approach of including these improved models into simulation algorithms is also presented with regard to large-scale power system simulation. The proposed large-scale simulation package is conceptually compared with other methods to determine the most suitable type of algorithm for system simulation including detailed synchronous machine, excitation system, and governor representation
