Consider two identical generating units with equal (4 %) speed-droop that operate in parallel

in accordance with the frequency-load characteristics as shown below.

(a) If both units are set to operate on curve A and the total load is equal to 100 % of the rating

of one unit, what percentage of rated kW output is each unit supplying and what is the

frequency of the common busbar?

(b) Repeat (a) if the total load is equal to 200 % of the rating of one unit.

the total load is equal to 100 % of the rating of one unit, what percentage of rated kW

output is each unit supplying and what is the frequency of the common busbar?

(d) Repeat (c) if the total load is equal to 150 % of the rating of one unit? How would you

characterize operation with any further increase in total load?.

Frequency Generator Rated Load %

A 106-102 100

B 104-100 100

Two identical firms (identical cost functions) operate on a market. For each of the following market demand curves and cost curves determine the Bertrand, Cournot, and Stackelberg outcomes (prices, quantities, and profits - for each firm, and at the market level). Also determine the collusive outcome (assuming the two firms form a cartel). Compare the outcomes. a) P = 200 − 2Q, T C = 50 + 10Q (PB = 10, PC = 73.33, PS = 57.5, PM = 105)...

A student placed equal volumes of honey and of water in two, identical, open dishes, and left them at room temperature for 8 hours. She observed that the amount of water decreased, but the amount of honey seemed unchanged. Knowing that honey is a highly concentrated solution of sugar in water, which statement should the student make to explain this phenomenon? Honey has a much lower vapor pressure than pure water has. So, pure water evaporates at a much higher...
