Simulation tools have been widely used for the design and improvement of electrical systems since the midtwentieth century. The evolution of simulation tools has progressed in step with the evolution of computing technologies. In recent years, computing technologies have improved dramatically in performance and become widely available at a steadily decreasing cost. Consequently, simulation tools have also seen dramatic performance gains and steady cost decreases.Researchers and engineers now have access to affordable, high
performance simulation tools that were previously too costprohibitive, except for the largest manufacturers and utilities. This paper introduces the role and advantages of using real-time simulation by answering three undamental questions: what is real-time simulation; why is it needed and where does it best fit.The recent evolution of real-time simulators is summarized. The importance of model validation, mixed use of real-time and
offline modes of simulation and test coverage in complex systems is discussed.

This paper describes a versatile, multi-domain, real-time digital simulator of large power grids. Its capability to
conduct multiple tests for protection coordination studies is described. A large grid model built using the EMTP-RV software
and simulated in real-time using the eMEGAsim real-time digital simulator and EMTP-RT software tool is described.
Comparisons between off-line and real-time simulations with different solvers are made using superimposed steady-state and
fault condition waveforms. A multiple random tests application for protection coordination studies using eMEGAsim simulator’s
built-in software TestDrive GUI and Python API scripting tool is described. The paper concludes with a discussion on the off-line,
real-time and acceleration modes of simulation of the PC-based eMEGAsim simulator and its advantages for studies of modern
power systems.

Wei Li, Jean-Nicolas Paquin, Jean Bélanger, Abstract
This document provides users with benchmark models to evaluate the OPAL-RT Technologies system configuration needed to develop research models for the following three HVDC transmission systems:
• Bipolar HVDC model,
• Monopolar back-to-back HVDC system based on the First CIGRE benchmark for HVDC control studies [1], and
• Multi-Terminal HVDC System.
The controllers and protections implemented in these models are described. Simulation results with additional comments are provided to demonstrate the feasibility of these models.
The studied systems are modeled in an environment that integrates Simulink/SimPowerSystems (SPS) with the eMEGAsim simulation platform, which incorporates the ARTEMiS software for solving of the real-time simulated model and the RTeDrive and RT-Events blocksets. This platform enables the simulation of increasingly large systems with real-time performance across multiple CPUs.
Through the use of the TestDrive graphical user interface platform from OPAL-RT Technologies, it is also demonstrated that observing results and modifying parameters and conditions on a real-time simulated model is both easy and user friendly.

Designing an All-Electric Ship (AES) requires testing of the interaction between hundreds of interconnected power electronic subsystems built by different manufacturers. Such integration tests require large analog test benches or the use
of actual equipment during system commissioning. Fully digital simulators can also be used to perform Hardware-in-the-Loop (HIL) integration tests to evaluate the performance of some parts of these very complex systems. This approach, in use for decades in the automotive and aerospace industries, can significantly reduce the costs, duration and risks related to the use of actual equipment to conduct integration tests. However the computational power required to conduct detailed simulation of
such diverse and numerous power electronic components can only be achieved through the use of distributed parallel supercomputers, optimized for hard real-time performance with jitter in the order of a few microseconds. Such supercomputers
have traditionally been built using expensive custom computer boards. This paper presents the technology and performance achieved by the eMEGAsim real-time digital simulator, which is capable of meeting these challenges through the use of standard
commercial INTEL quad-core computers interconnected by DOLPHIN SCI communication fabric. The precision achieved in the simulation of a detailed power electronic model implemented with SIMULINK and SimPowerSystems, and executed in parallel
with RT-LAB, will also be presented using a typical basic AES configuration. Furthermore, AES design implies the collaboration between several multidisciplinary teams using different tools to simulate all electrical, mechanical and fluid dynamic subsystems. The ORCHESTRA real-time co-simulation publish-and-subscribe framework enabling the integration of multi-domain simulation tools will also be presented.

To meet the growing demand for integration of renewable energy sources onto today’s power grids, many engineers from different specialized fields must be involved since various types of studies need to be conducted. The integration of distributed generation (DG) sources significantly changes the characteristics of an entire network. Such interconnection projects will require analysis of power quality, transient response to fault occurrences, protection coordination studies and controller interaction studies.
The first considerable challenge is related to power electronic converters, which are increasing in number and found on most DG sources. Accurately simulating fast switching devices requires the use of very small time steps to solve the system’s equations. Off-line simulation is widely used in the field, but it is time consuming if no precision compromise has been made on models (i.e. the use of average models). Moreover, off-line simulation tools do not offer the wide range of possibilities available with state-of-the-art distributed real-time simulators. Such tools combine, for instance, the efforts of control engineers and specialists from wind turbine manufacturers, who need to test their controllers using hardware-in-the-loop (HIL), together with those of network planning engineers from public utilities, who will conduct interconnection, interaction and protection studies. The eMEGAsim simulation platform is fully integrated with Simulink/SimPowerSystems (SPS) from The MathWorks and EMTP-RV. This makes eMEGAsim a valuable solution for engineers who already have models built with these off-line simulation applications, as well as for less experienced users. This paper focuses on the prototyping and testing of DG controllers using hardware-in-the-loop simulation. The model described in this paper is a 10-turbine wind farm connected to a single feeder, simulated using an eMEGAsim real-time simulator equipped with 8-processor cores. One of the wind turbines is controlled using an externally emulated controller. The emulated controller model consists of a replica of all other wind turbine controllers, which are locally simulated in the plant model. It is modeled and simulated using a dual-processor core real-time simulator, which interacts with the plant model via analog and fast digital inputs and outputs. This paper validates the proposed real-time simulator for the study of wind-farm electromagnetic disturbance studies with HIL-connected DFIG controllers, specifically that the simulator can be interfaced with high-frequency PWM controllers without distortions caused by the sampling time of the simulator.
