(3) Optimization results of generated output of each unit in various time periods: optimization
results of output of each unit in various time periods include area name, power plant name,
unit name, upper and lower limits of each unit output, and generated output of unit in
various time periods (24h). Due to space limitations, detailed results given here are the
outputs only for the north area, as shown in Fig. 2.11.
