Criteria for integration of intermittent renewable energy to the Java Bali Grid

Java Bali Grid has now reached the highest peak load ever at 25,325 MW on 15th September 2017, and the trend is going higher in the future. The fuel mix is dominated by fossil fuel such as coal and gas, and about 8.8% comes from dispatchable renewable energy of hydro and geothermal. Government has set a progressive target of 23% renewable energy in 2025 which may come from dispatchable and intermittent renewable energy. In order to maintain the smooth operation of Java Bali Grid, criteria for integrating the intermittent renewable energy must be set and stipulated through Grid Code. This criteria based on three basic pillars of system operation principle, which to fulfill the reliability and security of supply, the quality of supply and economic operation of the power system. This paper discuss the required criterias for integrating intermittent renewable energy to the Java Bali. The novely of this paper is as currently there is no standar has been set for integration of intermittent renewable energy to the Java Bali Grid, this paper proposes an approach to set criterias and requirements for the grid integration of renewable energy sources.
