Test Scenarios and Test Results for the Qualification of PV-Diesel Power Systems and Hybrid Controllers

PV-Diesel hybrid systems are consisting of different generators and storage systems whose operating behavior must be coordinated in order to reach a stable and secure power supply. In particular the diesel gensets and battery inverters as flexible power generators are the key components of such a system and play an essential role for the system behavior and control. In addition to test procedures for qualifying these components, this paper presents various exemplary results of laboratory tests. Furthermore, first results of system tests and significant influences on the control of such a system are shown.
