Problem 7. 100 MW is supplied by a conventional generator and a wind farm. Suppose the wind farm has a capacity of 40 MW 40% of the time and 90 MW 60% of the time. The conventional generator has a price of 0.1P, where P is its production. The wind farm has zero operating cost. Wind power is aways used before the conventional generator. How should the wind farm operate to maximize its profit? That is, the wind farm can generator any amount of power from 0 to its capacity, how much would it want to generate? i, i si i ] A load of

In the distribution transformer;In the transformer used for the distribution of electricity to the houses, 3.3 kilovolts enters and 400 volts come out. When we make the phase-neutral calculation, that is, when we divide it by √3, we get 230 volts and 220 volts coming to the sockets. Where does the remaining 10 volts go? (Can you explain with figure) is this about 30 degree phase shift?
