Integrating solar into the grid without storage. Set the number of EV cars and the solar power to zero. to zero. Set the Coal energy to 10. Find the minimum power you need from gas to satisfy the state's energy needs. This occurs when the gray curve is always greater than zero. Now, set the coal power to zero and the solar power to 10 and the coal power to zero. Find the power of the coal plant to meet energy needs. Include copies of both plots in your report. Does the coal plant power change if you also set solar to zero?
