1. A method, comprising:
- receiving, by a system comprising a processing device, area load forecasts that forecast conditions associated with a power grid, wherein respective area load forecasts are associated with a set of multi-stage engines that utilize different area load forecasting processes, and wherein at least one area load forecasting process is a security constrained unit commitment process and at least one other area load forecasting process is a security constrained economic scheduling process;
integrating, by the system, the area load forecasts into a composite load forecast, wherein the respective area load forecasts have different forecast time periods and include at least some overlapping forecast time periods, and wherein the integrating comprises merging overlapping portions of the area load forecasts based upon a weighted average of values in the overlapping portions according to respective weighting factors associated with the area load forecasts; and
executing, by the system via the set of multi-stage engines, a comprehensive operating plan based on the composite load forecast to dispatch resources of the power grid to generate power.
