Home Work-5 (Chapter-5) Incremental fuel costs (ROMWhr) for a power plant consisting two generating units are: * = 0,36 Pe +32 and generator limits are: 32 MW Pris 180 MW 22 MW Pas 130 MW. Determine P.P and values ofà for the variation of load from 54 MW to 310 MW. Assume that both generating units are operating at all times. Both by using (i) Analytical Technique and (ii) Iterative method.

a) The fuel costs of two operating units are as follows: c1=0.05P12 + 25p1+400 US$/hr c2=0.1P22 + 25p2+350 US$/hr If given that the minimum and maximum powers are 10MW and 1000MW for each unit, compar...
a) The fuel costs of two operating units are as follows: c1=0.05P12 + 25p1+400 US$/hr c2=0.1P22 + 25p2+350 US$/hr If given that the minimum and maximum powers are 10MW and 1000MW for each unit, compare the cost of the allocation of generation(dispatch) through an optimal strategy against an equal-share of generation strategy for a load of 100MW. Hence calculate the net loss/gain of the optimal strategy against the equal-share strategy b) The load for the power system consisting of two...

Problem 02) The system to be studied consists of two units as described as follows. Assume that the fuel inputs in MBtu per hour for units 1 and 2, which are both on-line, are given by H = 8P+0.024P2 + 80 H, = 6P, +0.04P + 120 Where, H = fuel input to unitn in MBtu per hour (millions of Btu per hour) (n = 1,2) Pr = unit output in megawatts (n =...

A steam power plant design consists of an ideal Rankine cycle with regeneration. Steam enters Turbine 1 at P1 and T1 at the rate of m1 and exits at P2. A fraction (y') of the steam exiting Turbine 1 is diverted to a closed feedwater heater while the remainder enters Turbine 2. A portion (y'') of the steam exiting Turbine 2 at P3 is diverted to an open feedwater heater while the remainder enters Turbine 3. The exit of Turbine...

A steam power plant design consists of an ideal Rankine cycle with reheat and regeneration. Steam enters Turbine 1 at P1 and T1 at the rate of m1 and exits at P2. A fraction (y') of the steam exiting Turbine 1 is diverted to a closed feedwater heater while the remainder is reheated to T3 before entering Turbine 2. A fraction (y'') of the steam exiting Turbine 2 at P4 is diverted to an open feedwater heater while the remainder...
