Emulation of power system load dynamic behavior through reconfigurable analog circuits

Emulation of power system dynamic load behavior is a viable alternative to popular simulation methods. In this paper, a circuit designed to emulate the dynamic behavior of power system loads is presented. It is constructed from common analog components and is fully reconfigurable via a set of analog input signals. As load behavior is heavily dependent on that of the external network, it is important to demonstrate how this reconfigurable analog load emulation module (RALEM) may be utilized in dynamic power flow studies. Such a demonstration is presented. These studies provide the network´s transient and steady-state flow of power in real-time or faster. This is of importance as popular simulation methods cannot provide a solution with such speed
