Efficient Location of Unsatisfiable Transmission Constraints in Look-Ahead Dispatch via an Enhanced Lagrangian Relaxation Framework

Multi‐level dispatch control architecture for power systems with demand‐side resources

“…Inter‐temporal constraints, such as generators’ ramping constraints, are incorporated by only considering the previous generation output, which is not designed to handle the future variability of load demands [26]. The look‐ahead dispatch [20, 27] is to expand a single snapshot‐based economic dispatch problem into a multi‐stage problem, which considers the future system constraints and future economic costs and provides the current dispatch schedules. Thus, the inter‐temporal constraints (constraints terms) and inter‐temporal benefits (objective terms) can be well taken into consideration in the optimisation process, which can improve the feasibility and the optimality of the system [20].…”

Power system flexibility: an overview of emergence to evolution

“…The other approach is the reserve analytical model which takes the operating and contingency reserve requirements into account with deterministic models [75][76][77][78]. In some cases [79][80][81][82][83][84], the look-ahead unit commitment (UC) and economic dispatch (ED) are employed to compensate for the net load (load minus VER generation) instead of the common real-time single-interval optimization models which cover the time-coupled multi-interval constraints.…”
