Photo thermal power generation, as a renewable energy technology, has broad development prospects. However, the operation and scheduling of photo thermal power plants rarely consider their internal structure and energy flow characteristics.

By introducing a virtual thermal plant and using properties of the M-matrix and Z-matrix, we have shown that the optimal generating power for the thermal power plants and the optimal C/D power for the storage battery change monotonically with respect to the net-demand variation. As a result, the exact regulating capacity can be determined for each thermal power
