“…Experimental results show that, with the current internet infrastructure, it is feasible to reach round-trip times within some milliseconds within distances in the order of hundred kilometers [3]. Such performance is in line with the main dynamics present at transmission level typically in the order of few hertz.…”

“…As described in Section III-B, the exchange of time-domain or EMT values among simulators imposes strong requirements on the sampling rate. Therefore, previous work already introduced dynamic phasors as a means of exchanging data in the frequency domain rather than the time domain [3]. The difficulty lies in the extraction of the dynamic phasors from the time domain signal for every simulation step.…”

The increase of faster dynamics in power systems has led to growing interest in new simulation solutions, especially in the field of hardware-in-the-loop and real-time simulation. Due to the size of power systems, detailed simulation of the faster dynamics is only feasible for a section of the system, whereas the rest is usually modeled as an infinite power bus. The aim of this work is to present a solution which would allow the representation of a significant portion of the dynamics that are usually not captured by the infinite power bus approach and enable the joint simulation among multiple simulation laboratories to share this dynamic model of the network beyond the boundaries of the detailed simulation. Furthermore, the presented architecture should allow the virtualization of each of these laboratories in cases where this coarse model of the neighboring grid sections is sufficient. First distributed simulation examples show the current status of our implementation of the architecture presented here.

“…Due to the frequency shift introduced by the DP approach, the sampling rate can be reduced [11]. For this feature, previous work already introduced DPs as a means of exchanging data in the time-frequency domain rather than the time domain [12]. The difficulty lies in the extraction of the DPs from the time domain signal at every simulation step.…”

The interconnection of power systems in conjunction with faster dynamics, caused by power electronics, increases the complexity of power system simulations for future grids. We propose an open platform as a solution which supports several important features. Grid models are stored in the Common Information Model (CIM) and the platform presents a uniform interface to several commercial and non-commercial Digital Real-time Simulator (DRTS) which can be used in parallel for co-simulation. A web-based interface is used to promote collaboration between research groups during planning and execution of simulation scenarios. Besides, this solution is designed for real-time simulation which allows the integration and testing of hardware components. Several components of the proposed platform have already been used for experiments and are available as open-source.

Distributed real-time simulation allows the sharing of simulator equipment and components connected in Hardware-In-the-Loop experiments. In this paper, we analyze the challenges of geographically distributed real-time power system simulation and how dynamic phasors could be applied to improve the accuracy of the simulation results for large time steps. The time step is of particular interest since the communication delay between simulators interconnected through wide area network is much larger than the simulation time step typically used in electromagnetic transient realtime simulations. However, commercially available real-time simulators use either the electromagnetic transient or classic complex phasor representation. Results in the dynamic phasor and electromagnetic transient domain are compared to quantify the advantage of dynamic phasor simulations in practice. The test platform for this evaluation is a power system simulator which is currently under development.
