MODELING AND SIMULATION OF HYBRID DISTRIBUTED GENERATION AND ITS IMPACT ON TRANSIENT STABILITY OF POWER SYSTEM


سال انتشار : 2013

نوع مقاله : IEEE JOURNALS & MAGAZINES

تعداد صفحات : 6

Abstract: The present grid is accommodating mixed energies

resulting into increasing complexities and instabilities. The dynamic

performance is measured by also considering the impact the

integration of new technologies such as distributed generation (DG)

and hybrid distributed generation (HDG) have on the grid. 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 more fault current

therefore making the system vulnerable to instability more than a

single energy source. This study investigates the dynamic impact of

hybrid Wind/ 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 variable

speed Wind turbine with doubly -fed induction generator (DFIG), 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.
