Analysis of power flow, continuous power flow and transient stability of IEEE-14 bus integrated wind farm using PSAT

Renewable energy systems are becoming necessary for higher power demands to compensate for maximum demand by the consumer. Wind energy system is one of the methods to generate power in connection with the conventional power systems. But when this wind farm is integrated to the grid system, the stability of the system tends to decrease. In this paper IEEE-14 Bus system using PSAT is used to evaluate the performance of the system, integrated with wind energy system, when subjected to fault. Using PSAT we first build an IEEE-14 bus test system and analyzed the performance by simulation. We introduced a three-phase symmetrical fault at various buses and study the voltage variations in all the buses with respect to time. We have connected a wind turbine at different buses and study the effect of wind power on the transient fault behavior. Our results show that the integration of wind farm has increased the transit stability of the system.
