چکیده

In this article, a comprehensive control scheme is designed on multimicrogrid system. The system is formed by several submicrogrids. In each submicrogrid, the dc and ac buses are linked via three single-phase converters. The hybrid wind/solar system based on Maximum power point tracking (MPPT) is utilized in the submicrogrids. The proposed control system balances the unbalanced loads, compensates the harmonics of nonlinear loads and supplies time-varying loads. The submicrogrids are designed to operate under both the islanded and grid-tied modes. In the islanded condition, the proposed model enables the submicrogrids to support each other for resilience improvement. Such model increases the load restoration following faults on both the dc and ac buses. The proposed model is tested on a typical multimicrogrid including five submicrogrids. The simulations are performed in MATLAB software. The results demonstrate that the developed scheme achieves all the purposes at the same time.
