| This paper presents the novel method of increasing short circuit current by means of interleaved power converter combined with kinetic energy storage. The proposed method provides a way to increase short circuit current delivered to circuit breakers without increasing overall cost of the power inverter. Use of interleaved topology allows for smooth connecting and disconnecting of kinetic energy storage to the system, which is done by temporarily disconnecting one of the inverters from the grid and using it to start spinning and synchronizing the flywheel of the energy storage to the island. It also reduces overall distortions generated by inverter during normal operation. This paper proposes a control algorithm and a method which allow to increase safety of the end users by increasing current flowing through circuit breakers during short circuits under island conditions. The proposed algorithm was tested in laboratory and results show that this solution has great potential in microgrid applications. |
