Emulation of power system dynamic load behavior This paper presents the design of a circuit capable of is a viable alternative to popular simulation methods. In this emulating the dynamic behavior of power system loads. It is paper, a circuit designed to emulate the dynamic behavior of constructed from common analog components and is fully power system loads is presented. It is constructed from reconfigurable via a set of analog input signals. The common analog components and is fully reconfigurable via a reconfigurable analog load emulation module (RALEM) is set of analog input signals. As load behavior is heavily utilized in dynamic power flow studies. This method is dependent on that of the external network, it is important to unique as: demonstrate how this reconfigurable analog load emulation module (RALEM) may be utilized in dynamic power flow a Emultion, uik p simulao methdsaesur studies. Such a demonstration is presented. These studies any solution isphysicallyrealizable. provide the network's transient and steady-state flow of power * Emulation, unlike simulation, time is in real-time or faster. This is of importance as popular controllable and independent of the system size simulation methods cannot provide a solution with such speed. and complexity.
In this work, the author discusses development of the Smart Electric Power System (SEPS) Laboratory at The College of New Jersey (TCNJ). The fully reconfigurable six-bus, three-phase power system hardware operates with ratings of 208 (at 60 Hz) and 0.2 kW. It is composed of various synchronous generators with associated prime movers, induction motors with associated dynamometers, transformers, transmission lines, contactors, constant-impedance loads, renewable generation-emulator modules, battery storage devices, and appropriate power electronic converters. The SEPS lab significantly expands the ability of faculty and students at TCNJ to study energy problems, providing a sound foundation for the institution's small but growing power engineering program. The National Science Foundation Major Research Instrumentation Program provided external funding for the hardware.
