Abstract

This study performs transi ent stability analysis for integrating wind power into an existing diesel-based remote/mini grid. A model was created of the eastern grid in Sumba Island, Indonesia, which has a network of diesel generators, three 20-kV buses, and primarily lighting load with a peak load of approximately 5.7 MW. The impact of integrating one 850-kW Type 3 wind turbine generator (WTG) is studied. During the high wind and low load scenario, the loss of the WTG or the loss of the largest conventional generator at a bus caused instability in the grid. The addition of a 500-kW storage unit, hybrid power plant controller, and the designation of an existing 550-kW diesel generator with 10-second cold-start time as the backup were used to stabilize the grid. This solution was shown to improve the reliability of the energy supply, enhance the stability of the system, and reduce greenhouse gas emissions. With the potential for minigrids/microgrids to provide power to 620 million people in Africa, the proposed solution has significant applicability.
