Indonesia has a great solar energy potential because its location is in a tropical area. One significant characteristic of solar energy is intermittent. Integration of intermittent renewable energy source (IRES) especially solar energy into electrical power grid can cause significant impact in power system stability. This study aims to model the IRES characteristic, profile, and time duration classification based on collected data in Cipayung microgrid system. The result shows the characteristic of IRES consist of two things, a sudden increase and suddenly decrease of solar source. These characteristic profile model is made by a polynomial and logarithmic regression analysis using mathematical equation. A condition where the availability of solar energy is immediately at a maximum or at a lowest point of zero has never been found. The very fast IRES classification occurs the most often with 0.5 to 1.0 minutes of time duration. System operator can use this information to prevent the system from collapsing and even having a blackout.
