A power system includes a turbine assembly including a turbine and a turbine shaft, a generator assembly including a generator and a generator shaft, an inertia assembly including a flywheel coupled to the generator shaft, and a clutch assembly for coupling the turbine shaft to the generator shaft. The clutch assembly is transitionable between a closed state, in which the turbine shaft is coupled to the generator shaft, and an open state, in which the turbine shaft is decoupled from the generator shaft. The power system is operable in a power generation mode when the clutch assembly is in the closed state and a synchronous condenser mode when the clutch assembly is in the open state.

Power systems having an inertia assembly and methods for operation

A system is provided. The system includes a plurality of uninterruptible power supplies (UPSs), a ring bus, a plurality of chokes, each choke of said plurality of chokes electrically coupled between a respective UPS of said plurality of UPSs and the ring bus, and a plurality of series compensators, each series compensator of the plurality of series compensators electrically coupled between an associated choke of the plurality of chokes and the ring bus.

Systems and methods of dynamic reactive power support for a power transmission system are provided. In one embodiment, a method of dynamic reactive power support for a power transmission system includes at least one circuit breaker connecting a shunt capacitor bank containing at least one shunt capacitor with a metal oxide varistor (MOV) connected in parallel. A controller is used to detect a voltage drop at the power transmission system (e.g., substation bus). In response to detecting the voltage drop, the controller closes the circuit breaker(s) connecting the shunt capacitors to the power transmission system. The controller then monitors at least one MOV to detect a current flow. Upon detection of a current flow in the MOV, the controller disconnects one or more shunt capacitors from the power transmission system by opening one or more circuit breakers. The shunt capacitors may be disconnected simultaneously, sequentially, in groups, or otherwise.
