“…Rather than solving the Kirchhoff network equations by means of heavy matrix algorithm, it uses instantaneous analog computation [1] [2]. Then, models of generators and loads are computed on low-cost FPGAs that contains a dedicated pipelined architecture [4]. Analog-todigital (ADC) and Digital-to-analog (DAC) high-speed converters provide the interface between the two computation methods.…”

Abstract-This paper presents an innovative 3D hardware architecture for power system dynamic and transient stability. Based on an intrinsic parallel architecture by means of mixedsignal circuits (analog and digital) it overcomes the speed of numerical simulators for given models. This approach does not competing the accuracy and model complexity of the high performance numerical simulators. It intends to complement them with the advantage of speed, low-cost, portability and autonomous functions. The presented architecture provides an ultra-high speed platform by means of emulation principle. The proof of concept is an array of 4x24 nodes reconfigurable platform. Hardware details and comparisons with a reference digital simulator are given.Index Terms-Emulation, mixed analog digital integrated circuits, application specific integrated circuit (ASIC), power system simulation, power system stability, power system dynamics.

Abstract-This paper describes a mixed-platform framework dedicated to Dynamic Stability Assessment of power systems. DSA refers to tools capable of characterizing the dynamic stability of the system. Time domain simulation is critical for DSA analysis and is done by algorithms known as TD engines. In this work, operations are shared between a software platform and a hardware one. TD simulation is handled by a dedicated mixed-signal electronics implementation. Data flow control, user interfacing, configuration, result post-processing and other auxiliary operations are realized in software. This architecture combines the flexibility of the software with the highperformance of dedicated hardware. Results of a multicontingency analysis and a critical clearing time determination analysis for sample test cases are presented. It is demonstrated that an increase in speed of almost three orders of magnitude can be achieved, compared to single-platform solutions.
