“…Different scenarios and operation cases, especially worst cases that cannot be tested in the real network, were simulated and the results obtained were mathematically analyzed offline and improved to reach the most appropriate algorithm for solving voltage problems caused by DGs or different operation cases. These insights led to different redesigns and development iterations [18], [23].…”

“…As an example test case to show the issues and advantages provided when testing a controller using C-HIL, the development of a central voltage control unit (CVCU) in the project DG-DemoNet [18] is used. The controller is used for the coordinated voltage control in a medium voltage network using a tap changer controlled transformer and the reactive power of controllable DGs.…”

This paper describes the process of developing and validating controller concepts using real-time simulation capabilities. The process from the proof-of-concept to the prototype and finally to the realization and the advantage of testing in a realtime simulation environment is demonstrated in a test case. The test case is based on an example in the safety critical domain of electric power systems -the coordinated voltage controller of the DG-DemoNet project. The possibilities and advantages of controller-hardware-in-the-loop (C-HIL) concepts compared to offline simulation are discussed.

“…1 an On-Load Tap Changing (OLTC) transformer is used in this smart grid solution together with reactive and active power control provided by DERs and electric storages. The goal of this application is to keep the voltage in the power distribution grid in defined boundaries due to distributed generation and to increase its hosting capacity with a high share of renewables [14]. The corresponding control approach has to calculate the optimal position of the OLTC and to derive setpoints for reactive and active power which is communicated over a communication network to the DER devices and electric storages.…”

Renewable energy sources are key enablers to decrease greenhouse gas emissions and to cope with the anthropogenic global warming. Their intermittent behaviour and limited storage capabilities present challenges to power system operators in maintaining the high level of power quality and reliability. However, the increased availability of advanced automation and communication technologies has provided new intelligent solutions to face these challenges. Previous work has presented various new methods to operate highly interconnected power grids with corresponding components in a more effective way. As a consequence of these developments the traditional power system is transformed into a cyber-physical system, a smart grid.Previous and ongoing research activities have mainly focused on validating certain aspects of smart grids, but until now no integrated approach for analysing and evaluating complex configurations in a cyber-physical systems manner is available. This paper tackles this issue and addresses system validation approaches for smart grids. Different approaches for different stages in the design, development, and roll-out phase of smart grid solutions and components are discussed. Finally, future research directions are analysed.Keywords: smart grid; simulation; hardware-in-the-loop; research; infrastructure; education; training IntroductionEnergy efficiency and low-carbon technologies are key enablers to mitigate the increasing emission of green-house gases still resulting in a global warming trend [1]. The efforts to reduce greenhouse gas emissions also strongly affect the power system. Renewable sources, storage systems and flexible loads provide enhanced possibilities but power system operators and utilities have to cope with their fluctuating nature, limited storage capabilities and the typically higher complexity of the whole infrastructure with a growing amount of heterogeneous components [2]. Additionally, due to changing framework conditions, like the liberalization of the energy markets and new regulatory rules, as well as technology developments (e.g., new components), approaches for design, planning, and operation of the future electric energy system have to be restructured. Sophisticated component design methods, intelligent information and communication architectures, automation and control concepts as well as proper standards are necessary in order to manage the higher complexity of such intelligent power systems (i.e., smart grids) [3][4][5]. Besides technical challenges also economic, ecological and social issues have to be addressed in smart grid research and innovation, too.During the last decade-especially in the past framework programs of the European Commission (i.e., FP6 and FP7)-a growing number of research and technology development activities have already been carried out in this area. Their main attempt was to fulfil the challenging goals and needs of the Strategic Energy Technology Plan (SET-Plan) of the European Commission for a sustainable environment and to foster the inno...

“…The results showed that the phase-wise OLTC can significantly improve the penetration of PVs, since it reduces phase-neutral voltage deviations from the rated value, with acceptable increases of the voltage unbalance factor. Regarding field trials, [26] and [27] In this study, we aim to examine the control logics of a phase-wise on-load tap-changer transformer in an experimental low-voltage network, considering the line-drop compensation technology. To achieve the objective, the experimental low-voltage system is built and three types of control logic with regard to the OLTC are studied in the system.…”

“…In addition, the current studies focus on simulation-based validation that means experimental-based validation is still largely missing in the literature. To address the aforementioned problems, several studies are performed to investigate the control performance provided by a single-phases on-load tap-changer transformer [21]- [25] and validate the OLTC control in an experimental environment [26], [27].…”
