Power hardware-in-the-loop (PHIL) is a powerful technique that allows researchers to test hardware under different operating conditions and environments. PHIL creates a closed-loop environment, where a single physical device is coupled to a simulated rest of system. This simulation operates in real-time, and provides a realistic view of the device's characteristics while under performance. The connection between the simulated and physical world happens through the PHIL interface. This interface is what allows the device to be tested under countless conditions, but it comes at a cost. The non-ideal behavior of the PHIL interface frequently results in distortions in the measurements. The most commonly of those distortions is a `two time-step delay' introduced due to the communication between the systems. Although this distortion is small (id est typically a phase shift of a few degrees in high frequencies), it is a distortion nonetheless. Therefore, it is imperative that estimations on the accuracy of PHIL interfaces are performed. In an extension of PHIL, multiple-interface power hardware-in-the-loop, or multi-PHIL for short, allows users to use multiple PHIL interfaces in a single experiment. This provides even more possibilities to an already powerful technique, allowing the testing of novel energy storage solutions, converters, and much more. To fully utilize the benefits of multi-PHIL however, its accuracy must first be validated. Since more interfaces are involved, the distortions seen can quickly grow, possibly leading to inaccurate results or unstable experiments. For those reasons, it is necessary to better understand and assess the accuracy of the PHIL interfaces in a multiple-interface power hardware-in-the-loop setting. A multi-approach solution is required to better understand the misrepresentation as it pertains to multiple PHIL interfaces. The first approach is to expand on already known accuracy and error metrics. The chosen approach in our case is a matrix based approach based on the Extended Lawrence Architecture (ELA). The ELA determines the behavior of a linear PHIL system, and serves as the foundation for our assessments. This approach is persuasive, but it often requires detailed models of the entire system. These models are not always available however, which demand a more practical solution. The second approach involves empirical measurements and experimental results. By performing a series of impedance measurements, information that is equally as useful to the accuracy assessment can be obtained. Although not as elegant as the ELA approach, this approach provides a partial solution to the problem without the requirement of detailed models. To ensure that these solutions fit a wide range of practical applications, a general common bus multiple-interface power hardware-in-the-loop system is designed. This system composes of any number of physical and simulated sub-systems connected to a common dc-bus. Each individual physical sub-system is coupled through to the real-time simulation through its personal interface. This allows for the creation of systems that mimic a shipboard power systems or the power grid. In order to facilitate the accuracy analysis of multi-PHIL simulation, a third approach to the matrix approach is suggested. This novel approach creates transfer functions based on the matrix approach. This approach also allows for the combination of different types of interfaces in the same PHIL experiment. This includes the possibility to expands on this idea by modeling dc-dc amplifiers as interfaces. This simple modeling of amplifiers broadens the applications of the generalized case, as it presents a more realistic portrayal of power systems.

Energy efficiency and low-carbon technologies are key contributors to curtailing the emission of greenhouse gases that continue to cause global warming. The efforts to reduce greenhouse gas emissions also strongly affect electrical power systems. Renewable sources, storage systems, and flexible loads provide new system controls, but power system operators and utilities have to deal with their fluctuating nature, limited storage capabilities, and typically higher infrastructure complexity with a growing number of heterogeneous components. In addition to the technological change of new components, the liberalization of energy markets and new regulatory rules bring contextual change that necessitates the restructuring of the design and operation of future energy systems. Sophisticated component design methods, intelligent information and communication architectures, automation and control concepts, new and advanced markets, as well as proper standards are necessary in order to manage the higher complexity of such intelligent power systems that form smart grids. Due to the considerably higher complexity of such cyber-physical energy systems, constituting the power system, automation, protection, information and communication technology (ICT), and system services, it is expected that the design and validation of smart-grid configurations will play a major role in future technology and system developments. However, an integrated approach for the design and evaluation of smart-grid configurations incorporating these diverse constituent parts remains evasive. The currently available validation approaches focus mainly on component-oriented methods. In order to guarantee a sustainable, affordable, and secure supply of electricity through the transition to a future smart grid with considerably higher complexity and innovation, new design, validation, and testing methods appropriate for cyber-physical systems are required. Therefore, this book summarizes recent research results and developments related to the design and validation of smart grid systems.

Modern power and energy systems are characterized by the wide integration of distributed generation, storage and electric vehicles, adoption of ICT solutions, and interconnection of different energy carriers and consumer engagement, posing new challenges and creating new opportunities. Advanced testing and validation methods are needed to efficiently validate power equipment and controls in the contemporary complex environment and support the transition to a cleaner and sustainable energy system. Real-time hardware-in-the-loop (HIL) simulation has proven to be an effective method for validating and de-risking power system equipment in highly realistic, flexible, and repeatable conditions. Controller hardware-in-the-loop (CHIL) and power hardware-in-the-loop (PHIL) are the two main HIL simulation methods used in industry and academia that contribute to system-level testing enhancement by exploiting the flexibility of digital simulations in testing actual controllers and power equipment. This book addresses recent advances in real-time HIL simulation in several domains (also in new and promising areas), including technique improvements to promote its wider use. It is composed of 14 papers dealing with advances in HIL testing of power electronic converters, power system protection, modeling for real-time digital simulation, co-simulation, geographically distributed HIL, and multiphysics HIL, among other topics.
