1. Consider a power system with the four generators listed in the table below. a. For each generator, calculate the marginal cost (fuel cost plus variable O&M cost per MWh generated) of each generator in units of $/MWh, and fill in that column of the table. Remember to show your work in calculating the total marginal cost. b. Supposing that the demand for electricity during a specific hour was 3000 MWh, use economic dispatch to determine the resulting output of each of the four generators and give the resulting system lambda.
