Distributed Control of Interlinking Converter for Adaptive Operation of Hybrid Microgrid

This work presents distributed control of interlinking converter for adaptive operation of hybrid microgrid. The hybrid microgrid consists of canal based small hydro generation combined with solar panels. The hybrid microgrid is modelled in such a way that it meets both AC and DC load demand. A battery based energy storage unit (ESU) is used, that balances the DC bus whereas the interlinking converter (ILC) balances the AC bus frequency and voltage. Besides various operating modes of the interlinking converter, PV converter and ESU converter in the standalone and grid synchronized mode are also tabulated. The harmonics and reactive power demand of the local loads are supplied by the ILC. The hybrid microgrid is simulated on a MATLAB/Simulink platform to validate the modes of operation.
