Abstract
Grid operators are facing new challenges in managing the power system due to lower inertia, more renewables and increased penetration of distributed generation. The advent of Wide Area Monitoring Systems (WAMS) provided operators with much greater insight into the dynamic behaviour of power systems which is now evolving to include control functionality to manage these fast dynamics. Wide-area observability within a control scheme provides the ability to develop new techniques for control which can take into account the larger power system behaviour, while co-ordinating the response across the grid where many resources can make up a response, including distributed generation.
However, the design and validation of wide-are-control schemes can be a challenge due to the number signals and possible resources available. In addition, as every power system is different, each wide-area control scheme must be tailored for that system. ePHASORSIM from OPAL-RT provides an ideal platform to enhance this process, incorporating a customer power system model in a closed loop environment which brings significant benefits to accelerating the evolution of wide-area control systems and delivering maximum value to the customers.

Abstract
This talk presents a framework for using information & communication technology (ICT) monitoring information to provide another dimension to the reliability/security assessment of physical measurement data used in power system decision making. ICT monitoring information covers the health of (1)operational technologies through monitoring of resources such as CPU, memory or network interfaces and (2) communication channels by monitoring the network traffic. This information may be used as an additional trust index to measurements that feed into SCADA applications such as voltage stability assessment, state estimation and contingency analysis in terms ofdecision making. This is especially important in case of failures, malfunctions, and attacks affecting the system robustness and safety. The presentation demonstrates the added value of ICT health information to state estimation. The proposed framework is integrated with a real-time co-simulation platform for multi-domain testing and evaluation of additional applications.

Abstract
Power hardware-in-the-loop (PHIL) simulations have been increasingly looked upon for design-testing and validation of equipment in various stages of the engineering design and deployment projects. It allows the users to test devices with higher flexibility than a full-scale deployed testbed. However, the process of setting up a PHIL simulation is not straight forward as the PHIL interface, if not designed correctly, may de-stabilize and otherwise stable system. Therefore, the process of setting up a PHIL simulation requires careful consideration of various elements to ensure a stable interface. These considerations along with the use of PHIL in different application areas will be presented. The speaker will also introduce solutions offered by OPAL-RT Technologies in the PHIL application area.

Abstract
V2X promises to improve safety on the road by relaying information among vehicles to help reduce collisions and loss of life. The technology must operate with extreme reliability in a very dynamic environment, with high relative speeds, very low latency for dynamic connections and safety-critical message receipt, in crowded urban environments with interfering signals. V2X systems will use competing technologies including DSRC and C-V2X. However, there are many issues which will need to be resolved. Congestion on the roads will affect the ability to communicate, and mitigation strategies need to be developed. Security of the networks will be needed for trustworthiness. Significant testing will be needed to guarantee interoperability among devices.
The presentation will explain how lab-based simulation that includes urban environments, vehicle mobility, fading, path loss, interference, and cyber security is being used with real radios in-the-loop, under varying conditions with thousands of moving vehicles, to greatly reduce testing time, space, and cost.

Abstract
Simulation is widely used for the development of modern electric drives that constitute electric vehicle (EV) propulsion systems. Using conventional offline simulation, it is possible to design and fine tune their controllers, and also to evaluate system performance under steady state and short transient conditions. However, in the EV context, it can be of great interest to analyse the performance of the power system and its control and modulation algorithms under realistic driving conditions, as this can provide valuable information regarding efficiency, autonomy and thermal cycling, among others. However, driving cycles include long transient conditions that are unfeasible to be simulated in a reasonable time frame when conventional simulation approaches are followed. Considering all these, the experience of the Applied Electronics Research Team (UPV/EHU) regarding real-time simulation of EV propulsion systems in an OP4510 platform is covered in this presentation, with special emphasys on implementation details and on the usage of the eHS solver for this purpose.

Abstract
This paper proposes a cyber-physical framework for investigating distributed control systems operating in the context of smart-grid applications. At the moment, the literature focuses almost exclusively on the theoretical aspects of distributed intelligence in the smart-grid, meanwhile, approaches for testing and validating such systems are either missing or are very limited in their scope. Three aspects need to be taken into account while considering these applications: 1) the physical system, 2) the distributed computation platform, and 3) the communication system. In most of the previous works either the communication system is neglected or ersimplified, either the distributed computation aspect is disregarded, either both elements are missing. In order to cover all these aspects, we propose a framework which is built around a fleet of low-cost single board computers coupled with a real-time simulator. Additionally, using traffic control and network emulation, the flow of data between different controllers is shaped so that it replicates various quality of service (QoS) conditions. The versatility of the proposed framework is shown on a study case in which 27 controllers self-coordinate in order to solve the distributed optimal power flow (OPF) algorithm in a dc network. Keywords: cyber-physical systems, smart grid, distributed control and optimization.

Abstract
Full vehicle simulation models are needed to assess attributes such as fuel economy and performance. In this session, you will learn how MathWorks automotive modeling tools can be used for powertrain selection studies. Specifically, we will examine the impact of adding an electric motor at different locations along the driveline (e.g., pre- or post-transmission). In order to make a fair comparison between alternatives, an optimal supervisory control strategy known as ECMS (Equivalent Consumption Minimization Strategy) is applied. With these closed-loop models, we can quantify the performance / fuel economy tradeoffs for the architectures under consideration and determine an optimal powertrain selection.

Abstract
Inverter team at Karma Automotive provides in-house development of power inverters (HW and SW) for world-class Karma EVs. As a main step in inverter SW and HW development, we developed a Hardware-in-the-Loop unit and an inverter fast prototyping tool. The Hardware-in-the-Loop unit is a main tool for SW development task, and it is now being extended to include SW verification tests, too. On the other hand, the fast prototyping tool is an essential tool to facilitate the implementation of inverter HW for the future EV platforms. This unit also provides a powerful tool for development of SW application layer with the possibility of high frequency sampling and monitoring.
The presentation file will discuss the structure of Hardware-in-the-Loop unit (power stage and monitoring) using OP5700 platform and its interaction with control board via CAN bus. It also covers the CAN unit of OP5700 platform to be used for implementation of automatic verification tests. As another discussion, the development of the fast prototyping tool (including motor control algorithm, protection, diagnostics, and CAN communication) using OP4510 platform will be discussed. The testing of the fast prototyping unit with the hardware-in-the-loop unit will be also presented.

Abstract
Several projects involving power electronic based equipment such as HVDC links, static VAR compensators and wind power plants have been decided and build by RTE. In the long term, the share of power electronics connections into existing ac systems will significantly increase due to the massive penetration of wind power plants and HVDC links. For several years, the French TSO (Transmission System Operator) RTE, has been involved in research and development activities to model and study power electronic devices. To support these activities, numerical tools are needed that offer detailed modeling HV components and controls while maintaining a good compromise between robustness, accuracy, and flexibility.
This presentation illustrate how replicas are used at RTE to improve system operation since 2011. This solution will be presented with real events that occurred on the French grid with HVDC devices. Special incidents are presented, that is: DC cable fault event and AC emulation behavior due to inter-area oscillation. Also, the paper explains how real-time simulation with physical controls supports maintenance, training and R&D activities by providing robust and reliable tool.

Abstract
The future integration of multi-terminal HVDC networks into the European power grids presents novel challenges to transmission grid operators, grid planners and manufacturers. A major obstacle to building HVDC networks is the limited experience available regarding their control and operation as well as their interaction with AC transmission systems and offshore wind power plants. To address these issues a laboratory-scale multi-terminal HVDC demonstrator – the MMC Test Bench – has been built at RWTH Aachen University within the framework of the EU-Horizon2020 Project PROMOTioN. At the heart of this PHiL demonstrator are eight laboratory-scaled Modular Multilevel Converters (MMCs) which are embedded in a real-time simulation of the surrounding AC systems by employing four-quadrant linear power amplifiers.
Within this presentation the setup of the PHiL demonstrator, the corresponding research objectives and first results regarding the controllability of HVDC networks in combination with offshore wind power plants are presented.

Abstract
Provision of services over the current structure of power grids with a large number of actors, e.g. distributed energy resources (DER) and active consumers, relies heavily on Information and Communication Technologies (referred to as grid automation system) for metering, processing, communicating and decision making. Moving towards digitalized complex power systems with their unpredictable and susceptible nature, the risk of disruptive events with large magnitude and consequence becomes higher. The grid automation system as a significant integrated component of the power system has to be designed to deal with these disruptive events as well, regardless the origin of the event (e.g. from physical or cyber side). This talk focuses on the significance of real-time simulation infrastructure in validating and development of intelligent grid automation solutions.

Abstract
System-level analysis capability, centered on modeling and simulation, has been identified as a key enabling technology for solving integrated power system challenges and high-performance power emulation pushes the boundaries of what can be tested prior to full system integration. For example, DC power systems are being applied in an increasing number of applications ranging from EV / HEV automobiles to More Electric Aircraft (MEA) to data centers and micro grids. The stability of these DC power systems is of critical importance to their operation. The presence of constant power loads and bidirectional power flow of many of the loads along with the parasitic inductance and distributed capacitance makes accurate calculation and simulation of stability margins challenging at best.
A bi-directional power source with a controllable bandwidth that can exceed the bandwidth of the fastest load can provide a means of determining system margin. The design and capabilities of the Direct Current Emulator (DCE) from D&V Electronics will be presented as well as using this capability to design and test DC power systems. The DCE can be controlled by a high-speed fiber optic interface with sub-microsecond latency for real time simulation Power Hardware In the Loop (P-HIL) to verify small signal stability analysis. Full DC power systems and power system components can be tested using the DCE as either a bi-directional load to load the power system or as a source to test components intended to connect to the DC power system. When the DCE is emulating the DC power system to test components it can be configured as a controllable source impedance and can generate transients and controlled noise and ripple. In combination with D&V’s electric motor emulator, also capable of real time simulation P-HIL, full vehicle system integration and component compatibility testing can be achieved.

Presentation:
In this presentation, we will discuss about using eHS to develop NI controller for DC Fast Charging System (DCFCS) including a local battery storage system.
The key challenge for fast EV charging is the limitations of the existing power grid infrastructure. Fast charging requires a large amount of energy in a very short time, and the distribution power grid was not designed for this. Therefore, the DCFCS includes a battery storage system to reduce the impact of DCFCS that is incurred during charging. Power electronics converter configuration, its controller design and development of a 60-kW prototype will be discussed in this presentation.
