Electric Power Grid and Natural Gas Network Operations and Coordination

The Hidden Flexibility of the Natural Gas Network for Electric Power Operations: A Case Study of a Near-Miss Winter Event

“…• Changes to Gas Nominations: Nominations, or the amount of gas requested for delivery, are typically submitted by gas-fired power operators in advance (e.g., a day ahead or in some cases several days ahead) and on a ratable basis (i.e., averaged over a 24-hour period). Moving to hourly or subhourly nominations may allow for (1) better capturing of the actual dynamics of gas usage of gas-fired power plants and (2) the gas network operator to plan around those dynamics (Peress and Karas 2017;Guerra-Fernandez et al 2020). More-regular updates to nominations, such as on over weekends (typically nominations submitted Friday are used for Saturday to Monday) may help provide more up-to-date operational information.…”
