The whole system control firstly has to satisfy the priority principle, namely priority solar energy, secondly valley electricity, and secondly flat electricity, and peak electricity is used as little as possible.
The control of the steam pressure in the steam boiler is maintained by adjusting the feed pump 9, when the load is reduced and the steam pressure is increased, the water supply is reduced or suspended to stabilize the steam pressure and the water level within the specified range, and vice versa.
