A two generator system supplying a load of 40MW connected at bus 2. The fuel costs of generators are:

C₁(P_G1) = 8500 Rs/MWh

C₂(P_G2) = 11000 Rs/MWh

The loss in the line is P_loss(p.u.)=0.5PG1_(p.u.)2 where the loss coefficient is specified in p.u. on a 100 MVA base. The most economic power generation schedule (in MW) is:

a)
P_G1 = 15.9 MVA, P_G2 = 13.2 MVA
b)
P_G1 = 19.9 MVA, P_G2 = 22.7 MVA
c)
P_G1 = 13.2 MVA, P_G2 = 15.9 MVA
d)
P_G1 = 22.7 MVA, P_G2 = 19.9 MVA

Correct answer is option 'D'. Can you explain this answer?

From coordination equation,

(dF_n/dP_Gn){1/ (1-∂P_L/∂P_Gn)} =λ

Given,

P_L=0.5P_G12

∂P_L/∂P_G1=P_G1 and ∂P_L/∂P_G2=0

(dF₁/dP_G1)(1/ (1-P_G1) = (dF₂/dP_G2) (1/ (1-0)

Or, 8500(1/ (1-P_G1) = 11000

Or, PG1=0.227 p.u.

As the base value is 100MVA.

PG1=100x0.227 = 22.7MVA

PL= 0.5x(0.227)² = 0.0258 p.u. = 0.0258x100 MVA = 2.58MVA

PD=P_G1+ P_G2- PL

Or, 40=22.7+ P_G2-2.58

Or, P_G2=19.9 MVA
