Influence of Large Scale Solar Power on Stability of East West Interconnector System of Bangladesh Power System

Renewable sources are independent of mechanical inertia, so their response to any power system is different than with any synchronous machine. As solar power is the most popular to get injected to any power system, their effect in any system is very important to examine in term of stability. This paper investigates the stability of east west interconnector system (EWIS) of Bangladesh power system (BPS) with the penetration of solar power in a large scale. As the loading limit and damping ratio increase with solar penetration, the results show the enhancement in power system stability in steady and dynamic state. The simulation model is organized and analyzed in NEPLAN software.
