Intermittent Renewable Energy Source (IRES) Penetration Level into Bangka Power System

Bangka is an island in Indonesia that have potential for the utilization of renvewable energy. One of the challenge using renewable energy source is intermittency characteristic. It will have a considerable impact on power system stability and reliability. The scenario aim to calculate how much intermittent renewable energy source (IRES) penetration level into the interconnected power system without causing frequency and voltage collapse based on applicable standards. The penetration level based on the worst scenario that may occur in the system during intermittency such as penetration in weak bus, dry season, maintenance of largest generator, peak load, and off-peak load condition. The result showed the IRES penetration level into the Bangka power system in off-peak load is about 0,01% but in peak load need to prepare spinning reserve with high possible ramp rates.
