Embodiment 2
[0160] combine figure 1 As shown in Fig. 1, a decision-making method for optimal quotation of solar thermal power plants based on robust stochastic model.
[0161] The technical data of a solar tower solar thermal power station are listed in Table 1. In order to make full use of solar energy resources, it is assumed that the thermal capacity of the optical field is large enough, so that the solar thermal power station can operate at full power during the period of the strongest solar radiation, and at the same time store the excess thermal energy in the heat storage device. Assuming that the initial heat storage capacity of the solar-thermal power plant at time t=0 is 350MWh, the solar-thermal power is zero at this time. Taking this as an example, the present invention provides a method for optimal quotation decision-making for photothermal power plants based on a robust stochastic model:
[0162] S1: Obtain the relevant technical parameters of grid-connected power generatio...
