Protecting Micro-grids containing micro-sources equipped with power electronics interfaces is a major challenge for engineers developing techniques to exploit renewable energy sources for electricity generation. Conventional techniques based on overcurrent protection have major limitations and new techniques have to be explored. The method described in this paper provides reliable and fast detection...
The protection of micro-grids containing distributed generation using solid state converters can not depend on monitoring the fault current to detect short circuit faults. In order to protect the semi-conductor devices, the output current from the converter is generally limited to about twice the unit's full load current. This paper describes an alternative and novel approach based on monitoring disturbances...
