- 2. INPUT-OUTPUT CHARACTERISTICS Input-Output characteristics is the fundamental curve for a thermal plant It is a plot of the input in British thermal units (Btu) per hour versus the power output of the plant in MW .
- 4. HEAT RATE CHARACTERSTICS The heat rate is the ratio of fuel input in Btu to energy output in KWh. It is the slope of the input – output curve at any point. The reciprocal of heat rate is called fuel efficiency. The heat rate curve is a plot of heat rate versus output in MW
- 6. INCREMENTAL FUEL RATE CURVE The incremental fuel rate is equal to a small change in input divided by the corresponding change in output. Incremental fuel rate = ∆𝐼𝑁𝑃𝑈𝑇 ∆𝑂𝑈𝑇𝑃𝑈𝑇 The unit is again Btu / KWh. A plot of incremental fuel rate versus the output
- 7. INCREMENTAL FUEL RATE CURVE
- 8. INCREMENTAL COST CURVE The incremental cost is the product of incremental fuel rate and fuel cost (Rs / Btu or $ /Btu). The unit of the incremental fuel cost is Rs / MWh or $ /MWh. The incremental fuel cost is given by 𝑑𝐹𝑖 𝑑𝑃𝐺𝑖 = bi + 2ci PGi Rs / MWh
- 10. INCREMENTAL COSTS OF UNITS OF THERMAL POWER PLANT The simplest case of economic dispatch is the case when transmission losses are neglected. The model does not consider the system configuration or line impedances. Since losses are neglected, the total generation is equal to the total demand PD
