Physics · Power Systems
Two hydro plants supply the same load. Plant A has higher hydraulic efficiency at high head but a long ramp time limit; Plant B has lower efficiency but a rapid ramp response. To minimize total fuel-equivalent cost during peak ramp events, the optimal short-term schedule will:
- 1Favor Plant A only due to its better efficiency
- 2Alternate equally between the two plants irrespective of ramp needs
- 3Favor Plant B only due to its ramp capability
- 4Use Plant B for ramping and Plant A for steady base output (mixed schedule)✓
Correct answer
Use Plant B for ramping and Plant A for steady base output (mixed schedule)
