Control-Hardware-In-the-Loop Simulation Studies with Remote Terminal Unit 540 from ABB

Abstract

Battery Energy Storage System (BESS) has come of age for widespread implementation to firm up the integration of renewable energy sources to smart grids. The substation automation system (SAS) has been the platform for deployment of automation functions for transmission and distribution systems since early days. The current architectures of SASs including those recommended by IEC-61850 do not support the integration of BESS for voltage and frequency supports as a default function. Further, the solutions for BESS integration from the industry have not been standardized owing to the fast pace developments in this field. ABB Australia has been the pioneer equipment supplier of BESS and system integrator for various pilot projects worldwide. In this study, the Remote Terminal Unit (RTU) 540 from ABB and the Power Factory simulation software from DIgSILENT (DPF) are used in a Control-Hardware-In-the-Loop (C- HIL) testing for BESS integration. The C- HIL system in this study will be the platform for ABB to verify the future BESS integration solutions. As a part of this study, the three-term linear controllers of Proportional-Integral-Derivative (PID) with dead - bands and first-order filters are designed for voltage and frequency support functions for the IEEE nine-bus benchmark power system. Simulation results demonstrated the success of the umbilical interfaces between the RTU 540 and DPF platform to be used in the verification of future BESS integration projects of ABB.
