Islanded Wind Farm Microgrid Stability Control Using Synchronverter Algorithm

Indonesia is an archipelagic country that has several remote islands. In terms of electricity supply, there are some remote islands that are difficult to get electricity supply, such as Adaut regency of west Maluku Indonesia. One solution to solve the electricity supply problem is the creation of a microgrid system. Microgrid can be utilized in island areas that difficult to get electricity. However, the application of renewable energy on microgrids can cause several technical impacts such as disturbances in frequency and voltage stability. Therefore, a control algorithm that can maintain the stability of the system is needed. One algorithm that recently developed is synchronverter. In this study, a synchronverter is used on islanded wind farm based microgrid to maintain network stability. We assess the microgrid stability performance by comparing the microgrid stability responses that using synchronverter algorithm or a conventional synchronous generator. The results of this study indicate that the synchronverter algorithm can maintain the stability of microgrid even it is interrupted by intermittent wind speed input and several load changes.
