Energyscheduling

Energyscheduling is the process of planning and coordinating generation, transmission, and demand resources to meet energy demand reliably and economically within a defined time horizon. It is typically performed by an electric system operator, utility, or energy market participant to balance supply and demand while respecting technical and market constraints.

Key components include load forecasting, unit commitment, and economic dispatch. Unit commitment decides which power plants are online for a period; economic dispatch determines the output level of online units. Scheduling operations occur across time horizons such as day-ahead, hour-ahead, and real-time, with the aim of minimizing operating costs and ensuring reliability.

Scheduling relies on mathematical optimization and simulation, using models such as linear programming, mixed-integer programming, and stochastic or robust optimization. It incorporates forecast data for demand, renewable generation, fuel prices, and outages, and must respect constraints on generator limits, ramp rates, transmission capacity, and reserve requirements. It also accounts for reliability criteria and market rules that govern bidding, pricing, and settlement.

Applications span large electric grids, microgrids, and industrial facilities with on-site generation. In electricity markets, energyscheduling interacts with power auctions, ancillary services, and capacity markets, shaping patterns of fuel use and emissions and influencing market prices and reliability.

Modern systems employ energy management systems, advanced SCADA, and market interfaces to execute schedules, monitor performance, and adjust plans in real time. Challenges include forecasting uncertainty, renewable intermittency, grid resilience, regulatory constraints, and cybersecurity considerations.
