Study on Renewable Penetration Limits in a Typical Indonesian Islanded Microgrid Considering the Impact of Variable Renewables Integration and the Empowering Flexibility on Grid Stability

摘要

This study assesses the impacts of variable renewabIes and the use of flexibility on frequency, voltage, and angle stability in a typical isolated microgrid in Indonesia. The simulations in Power Factory have illustrated the flexibility options and the stability behavior evolution, considering a parametric study on the shares of inverter-based variable renewable energy resources. The 10% limit of variable renewabIes in Indonesian microgrids is also discussed and proven to be rather pessimistic, as this research reaches the instantaneous penetration rate varying from 0% to 31.3% in the considered scenarios.
