Abstract:
The integration of hybrid distributed generation (HDG) is increasing today and the dynamic impact is difference from the single energy source due to differences in dynamic characteristics of the generators involve. Hybrid distributed generation with one or more renewable (stochastic) energy sources interact with the existing grid during import and export of power generation. This interaction contributes difference level of fault current therefore subjecting the system to difference transient instabilities compare to single energy source. This study investigates the dynamic impact of hybrid Wind/ Solar PV/small Hydro power on transient stability. To investigate this impact, a detail modeling of grid connected Wind/ Solar PV and Small hydropower system with single machine infinite system is carried out. The simulation was done in DIgSILENT power factory software. The configuration of the proposed typical grid connected hybrid distributed generation (HDG) consists of Converter Driven Synchronous Generator, Solar PV and Small hydropower system. The wind turbine is integrated through PWM converter into the existing Grid while the solar PV incorporated into the system consists of DC sources integrated through PWM inverter and the hydro power is directly connected through a synchronous generator.
