With increasing penetrations of variable energy resources on both the transmission and distribution systems, utilities need to adapt how they manage their resources to integrate the variable resources and load while maintaining reliability. One tool available to system operators to increase the flexibility of their thermal units is to reduce the minimum operating limit (also known as turn-down or P-min) of the unit as low as possible to be able to remain online until system conditions change. In the past, system planners and operators used manufacturer specifications to set the minimum operating limit of their thermal units, but given the increasing penetrations of variable energy, operators are pushing the limits of their plants to increase flexibility.
In this webinar, Debra Lew, Senior Technical Director at GE Energy Consulting, will discuss the importance of lowering P-min to increase system flexibility and what some utilities are doing to increase the operating range of their units.
Then Austin Park, Energy Resources Engineering Graduate Student at Stanford University, will discuss a data-driven approach to find the minimum operating limits for thermal generators in the West and how that information can be used to improve system operations and planning.
