Power hardware-in-the-loop (PHIL) simulation allows the connection of a physical power component (e.g., photovoltaic inverter) to a real-time simulated network. In this paper, PHIL simulation is used for laboratory education in a systematic way for the first time. Four important topics for the understanding of power system operation are selected and laboratory exercises are designed, respectively. The topics focus on the effects of increased integration of distributed generation (DG), namely, power sharing between synchronous generators and DG, voltage control with on load tap changer and DG, short circuits with inverter-based DG, and microgrid operation. The exercises start from the operation of the traditional power system and gradually incorporate DG-related topics that show both benefits and challenges. A hands-on approach is supported by the appropriate lab configuration consisting of two independent PHIL setups. The assessment of the laboratory exercises by the students is clearly positive underlining the value of PHIL simulation for power system education.

Comprehensive analysis of Distributed Energy Resources (DER) integration requires tools that provide computational power and flexibility. In this context, throughout this paper PHIL simulations are performed to emulate the energy management system of a real microgrid including a diesel synchronous machine and inverter-based sources. Moreover, conventional frequency and voltage droops were incorporated into the respective inverters. The results were verified at the real microgrid installation in the Centre for Renewable Energy Sources (CRES) premises. This research work is divided into two steps: A) Real time in RSCAD/RTDS and Power Hardware-in-the-Loop (PHIL) simulations where the diesel generator´s active power droop control is evaluated, the battery inverter´s droop curves are simulated and the load sharing for parallel operation of the system´s generation units is examined. B) microgrid experiments during which various tests were executed concerning the diesel generator and the battery inverters in order to examine their dynamic operation within the LV islanded power system. This work is co-funded by the European Commission within the Seventh Framework Programme (FP7/2007-2013) DERri under grant agreement no 228449.

With this document the work in the DERri “JRA3 Real time simulation environment and parameteridentification for power systems” will be finished. One main focus of this last deliverable is on thedescription of available real-time simulation and Hardware-in-the-Loop equipment available in laboratories of the DERri partners with special focus on the Power-Hardware-in-the-Loop approach.Moreover, the harmonization of applied rules and procedures for executing Power-Hardware-in-the-Loop is covered by this report. Also lessons learned and potential improvements of this advanced testing and validation method is provided by the DERri partners. A further focus of this deliverable is the validation of Distributed Energy Resource componentmodels using the DERri Common Reference Model. Therefore, reference implementations of selected models are compared with results from laboratory measurements and Hardware-in-the-Loopexperiments. Moreover, some remarks and conclusions regarding the modelling of Distributed Energy Resource components are presented. Finally, possible actions for further standardization work on Power-Hardware-in-the-Loop experiments and modelling of Distributed Energy Resource components are discussed.&nbsp
