1. An electrical power generating system, comprising:
a bypass conduit including a bypass control valve and a turbine;
a primary conduit including a primary control valve; and
a controller including executable instructions stored in non-transitory memory that causes the controller to:
responsive to a fluid flow rate through the primary conduit being greater than a minimum threshold flow rate, adjust a speed of the turbine in response to a downstream pressure while the bypass control valve is fully open,
where the downstream pressure is a pressure in the primary conduit downstream of the primary control valve.
