Impact of Wind Power Plant in Bangladesh Power System Stability

Government of Bangladesh has recently approved the maiden private wind power project of 55 MW in Bagerhat region. In this case the stability of Bangladesh Power System (BPS) is of prime concern as the behavior of renewable energy sources are different from non-renewable sources. Wind power based non-conventional source of energy integration may change the stability. Hence, this paper investigates the steady state, small signal and transient state stability replacing the conventional sources of generation with equivalent size in step by step for different penetration levels. Eigenvalue analysis technique is used to find out the oscillatory modes basically the critical modes and Hopf Bifurcation (HB) point. Doubly Fed Induction Generator (DFIG) is considered to model the Wind Turbine Generator (WTG) in Bagerhat. NEPLAN software is used to carry out all the simulations.
