Introduction
This paper demonstrates a co-simulation of an AS-PSH unit between penstock hydrodynamics and power system events in a real-time environment. There is a need for a more advanced and adaptable model that leverages computational fluid dynamics (CFD) to simulate complex transient behaviours, optimize guide vane closure timing, and provide visual insights, into pressure and flow patterns. In this study, a variable speed pumped storage unit is modeled in real time digital power system simulator and the performance of the system was analysed for various operating conditions for the machine operation.
