Distributed Verification and Validation Methods for Power System Dynamics and Control
Abstract
The program of work is divided into three main areas of basic research in the methodology,design, and techniques that can advance the capabilities and cost-effectiveness of simulationsystems:- Simulation Techniques for Real-Time Operation- Model Verification- Distributed System IntegrationDetails of each of these research areas are presented in the following sections:2.1 Simulation Techniques for Real-Time OperationA variety of linear and non-linear models that are of interest to the research partners will beimplemented with a goal of real-time execution to support use in distributed control systems,hardware-in-the-loop systems, system and subsystem verification and validation, and generalhigh speed simulations. Example models that may be implemented include induction motors,switches, transmission lines, transformers, controllable sources and loads, three-phase inverters,and photovoltaic arrays. Development of these larger, advanced models at real-time operationalso supports future endeavors of faster than real-time simulation and high-frequency switchingmodels. Supporting real-time operation of complex models at a small frame times requiresinvestigation of techniques for high-speed, accurate implementations of numerical methods,study of low latency communication mechanisms within and across multiple FPGA boards, andexpansion of the non-linear capabilities of the FPGA simulation system.CSU, Chico has considerable experience in implementing machine models in FPGAs and withinother technologies for real-time operation. New research in this proposal will develop methodsfor real-time operation at small frame times within FPGAs, expand non-linear capabilities fornon-linear models, and investigate methods to scale the system to handle more complex modelsand larger sets of models simultaneously over multiple FPGAs. These developments supportfuture faster than real-time operation and high-frequency switching systems. Models of interestto the US Navy will be provided by research partners at NAVSSES and Drexel University.2.2 Model VerificationVerification of the simulation results will be performed to ensure confidence in the use of thedeveloped simulation system. Multiple methodologies may be required to perform verificationdepending on the modeled component or system, with comparison to analytical models, modelsimplemented in other simulation systems, and experimental data possible. The nature of theverification method selected places different requirements on the FPGA simulation system forthe collection or comparison of data with some reference. Ensuring the accurate processing ofdata for verification purposes will require investigation of software and FPGA methods for bulkdata handling and comparison at reasonable speeds.CSU, Chico has performed verification against analytical models and models in Simulink formodels previously implemented in the FPGA simulation system. New research in this proposalwill expand system data collection and comparison to facilitate easier model verification,develop verification procedures and criteria with research partners, and investigate methods forcomparison of simulation results to experimental data collected on real systems.2.3 Distributed System IntegrationCSU, Chico research partners at NAVSSES and Drexel University have an interest in using theFPGA simulation system as a critical component of a distributed system for the study of thedynamics and control of power systems. The CSU, Chico FPGA simulation system could playmultiple roles within a larger distributed system for research partners, including providing fastersimulation results than existing systems, enabling hardware-in-the-loop simulation, supportingresearch on distributed control systems with real delays, and providing a platform for faster andsimpler verification and validation of system components and models. Integration into thedistributed system could occur through many possible direct or indirect communicationinterfaces. To support
