Analysis of Maximum Intermittent Renewable Energy Source Penetration on South of Sulawesi Power System

One of the adverse using renewable energy source is intermittency characteristic. It will have a considerable impact on power system stability and reliability. This study aims to calculate how much intermittent renewable energy source (IRES) penetration into the interconnected power system without causing collapse the system based on applicable standards. Stable conditions by standards must meet the acceptable voltage and system frequency. The level of IRES penetration based on the worst scenario that may occur in the system during intermittent such as penetration in weakest bus by sensitivity analysis, dry season, maintenance of largest generator, peak load, and off-peak load condition. The simulation showed the IRES penetration level into the South of Sulawesi power system are about 0,32% in off-peak load and about 5,24% in peak load.
