Refer to Problem, where three generator units have input-output curves specified as a series of straight-line segments. Can you develop a composite input-output curve for the three units? Assume all three units are on-line and that the composite input-output curve has as many linear segments as needed.

Problem
Thermal Scheduling with Straight-Line Segments for Input-Output Curves The following data apply to three thermal units. Compute and sketch the input- output characteristics and the IHR characteristics. Assume the unit input-output curves consist of straight-line segments between the given power points.

Fuel costs are:-

Compute the economic schedule for system demands of 300, 460, 500, and 650 MW, assuming all three units are on-line. Give unit loadings and costs per hour as well as total costs in $ per hour.
