Interoperability Control/Monitoring of Multi-Paralleled Inverters by IEC61850 Protocol

Parallel connection of inverters is one of the important issues of the power systems since their output voltage and frequencies change slightly. So that this study investigates the experimental results of interoperability control and monitoring of the multi parallel inverters based on IEC61850 protocol. Two smart inverters are tested in terms of the responsiveness by running them in parallel, at the same time, when the Frequency-Watt setting is changed by a Distributed Energy Resource Management System and operating them according to the Frequency-Watt specifications are examined in detail and the versatility of the test method is verified by performing tests on each of the inverter.
