MCQ (Single Correct Answer)

-0.6

A load center of 120 MW derives power from two power stations connected by 220 kV transmission lines of 25 km and 75 km as shown in the figure below. The three generators G1,G2 and G3 are of 100 MW capacity each and have identical fuel cost characteristics. The minimum loss generation schedule for supplying the 120 MW load is GATE EE 2011 Power System Analysis - Power Generation Cost Question 9 English

$$P1 = 80\,MW + $$ losses
$$P2 = 20\,MW$$
$$P3 = 20\,MW + $$ losses

$$P1 = 60\,MW $$
$$P2 = 30\,MW$$ $$+$$ losses
$$P3 = 30\,MW $$

$$P1 = 40\,MW $$
$$P2 = 40\,MW$$
$$P3 = 40\,MW + $$ losses

$$P1 = 30\,MW + $$ losses
$$P2 = 45\,MW$$
$$P3 = 45\,MW $$
