Distribution networks are becoming increasingly smarter', as well as more complex, with the addition of power electronic devices, information and communication technologies, smart meters, and more. As a result, advanced control strategies to manage such networks are becoming necessary. These strategies need to be thoroughly tested and validated, before they can be implemented in a real network. For this reason, a smart grid control algorithm testing chain is proposed, that aims to gradually test control algorithms, in all their development stages, using increasingly advanced laboratory setups. In addition, the interfacing options and challenges of each stage of the chain are highlighted. The proposed testing chain is substantiated in an optimal centralised coordinated voltage control (CVC) algorithm and the final stage of the chain, namely the combination of control and powerhardware-in-the-loopsimulation, is presented in this study. As a specific example, the management technique for a storage system is implemented as part of the CVC algorithm. The laboratory results demonstrate that the proposed setup, despite its high complexity, enables the algorithm to be effectively and realistically tested as part of the overall system.

The integrated starter-generator system (ISGS) is a combination of starter and generator for independent power systems in transportation. It replaces both a conventional starter and generator with a single set of highly integrated devices. A powerhardware in the loopsimulation that is flexible and can include the hardware under test is used to test the ISGS under representative field conditions. This paper utilizes the special structure of the ISGS and proposes an ISGS emulator (ISGSE) to develop and test the converter. The proposed ISGSE can be used to test a variety of motor drives or rectifiers including dynamic capabilities without necessitating a connection to a large motor load. To emulate the ISGS, the structure and operation principle in different modes are introduced in detail. Also, the issue of stability and accuracy is discussed in this paper. Detailed simulation and experimental comparisons are carried out between the ISGS and the ISGSE, which validates the proposed ISGSE as an effective tool for designing and testing new motor drives.
