a power unit price record table generation module for generating a power unit price record table including each power unit price and a time period in which each power unit price is located;
The output power change curve generation module is used for generating an output power change curve of one power supply period of the new energy power generation side grid-connected end;
the dividing module is used for dividing a plurality of corresponding intervals in the output power change curve according to the time period of each power unit price;
the calculation module is used for calculating the power supply quantity of each section and multiplying the power supply quantity of each section by the unit price of the power corresponding to the section to obtain the power cost of the section;
And the settlement module is used for summing the electric power cost of all the intervals and settling out the income of the new energy power generation side.
6. The power grid-tie settlement system as claimed in claim 5, wherein: the power unit price setting module includes:
a setting unit configured to set an initial power unit price, a highest power unit price, and a lowest power unit price, the initial power unit price being a median value of the highest power unit price and the lowest power unit price;
a first acquisition unit configured to acquire a current power unit price; if the current power unit price is a null value, the current power unit price is an initial power unit price;
The adjusting unit is used for adjusting the current power unit price by a preset percentage when the power supply and demand relation is that the power supply and demand relation is larger than the power demand, judging whether the adjusted power unit price is smaller than the lowest power unit price, if yes, taking the lowest power unit price as the reset power unit price, and if not, taking the adjusted power unit price as the reset power unit price;
When the power supply and demand relation is the power supply and demand, the current power unit price is up-regulated by a preset percentage, whether the up-regulated power unit price is larger than the highest power unit price is judged, if so, the highest power unit price is taken as the reset power unit price, and otherwise, the up-regulated power unit price is taken as the reset power unit price;
