Pumped storage hydro (PSH) based generation of electricity is a proven grid level storage technique. A novel configuration i.e., Adjustable Speed PSH (AS-PSH) power plant is modeled and discussed in this paper. The hydrodynamic models are created using partial differential equations and the governor topology is adopted from an existing, operational AS-PSH units. Physics-based simulation of both hydrodynamics and power system dynamics have been studied individually in the past. This paper demonstrates a co-simulation based on AS-PSH units between penstock hydrodynamics and power system events in a real-time environment. Co-simulation provides an accurate insight into the dynamic and transient operation of AS-PSH connected to a bulk power system network. The two modes of operation of AS-PSH presented in this paper are turbine and pump modes. A general philosophy of operating in turbine mode is prevalent in the field when the prices of electricity are high and in the pumping mode when prices are low. However, recently there is renewed interest in operating PSH for providing ancillary services. A real-time co-simulation at sub-second regime of AS-PSH connected to the IEEE 14 bus test system is performed using digital real-time simulator and the results are discussed.
