Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a feasibility assessment method for cross-regional consumption of clean energy, and specifically, as shown in fig. 1, the feasibility assessment method for cross-regional consumption of clean energy includes:
and step S1, obtaining a correlation coefficient r of the wind power output characteristic of the sending end in the cross-regional consumption of the clean energy and the load characteristic of the receiving end in the cross-regional consumption of the clean energy.
For example, the correlation coefficient r between the wind power output characteristic of the sending end and the load characteristic of the receiving end can be obtained by fitting the wind power output characteristic curve of the sending end and the load characteristic curve of the receiving end, and it should be noted that, for a specific method for obtaining the correlation coefficient r between the wind power output characteristic of the sending end and the load characteristic of the receiving end by fitting the wind power output characteristic curve of the sending end and the load characteristic curve of the receiving end, a person skilled in the art may refer to the existing method for obtaining the correlation coefficient by curve fitting, and details are not repeated here.
If the value of r is positive, the wind power output characteristic of the sending end is positively correlated with the load characteristic of the receiving end; if the value of r is negative, the wind power output characteristic of the sending end is inversely related to the load characteristic of the receiving end; if the absolute value of r is equal to 1, the wind power output characteristic of the sending end is completely related to the load characteristic of the receiving end; and if the value of r is zero, the correlation between the wind power output characteristic of the sending end and the load characteristic of the receiving end is zero.
When r is greater than 0 and less than 1, and the larger the value of r is, the better the correlation between the wind power at the sending end and the load at the receiving end is, the relatively smaller the influence on the peak load regulation at the receiving end is, and the method is more suitable for being used as the sending end for the cross-regional consumption of clean energy.
And step S2, obtaining the ratio of the clean energy electricity abandonment amount of the sending end.
When the ratio of the electric quantity discarded by the clean energy is larger, the sending end system has weaker capacity of consuming the clean energy, has larger delivery demand, and is more suitable to be used as a sending end for consuming the clean energy across areas.

It should be noted that "centralized access" in the embodiment of the present invention refers to: and the voltage class of more than 10kv is switched in.
When the value of the clean energy capacity ratio η of the centralized access is larger, it means that the access ratio of the large capacity of the transmitting end system is higher, and the transmitting end system is more suitable for consuming the clean energy across the region.
And step S4, acquiring the power supply installed ratio of the peak shaving depth in the receiving end above 50%.
When the value of the power supply installed proportion of the peak shaving depth of more than 50% is larger, the power supply with stronger peak shaving capacity of the receiving end is higher, and the receiving end is more suitable for receiving clean energy transmitted by the transmitting end.
Step S5, obtaining a comprehensive evaluation coefficient R of the trans-regional consumption of the clean energy according to the correlation coefficient R, the proportion coefficient of the electric quantity discarded by the clean energy, the proportion coefficient η of the capacity of the centrally accessed clean energy and the installed proportion of the power supply with the peak shaving depth of more than 50%, wherein R is omega1×r+ω2×+ω3×η+ω4×, wherein ω is1Is a weight coefficient, ω, of the correlation coefficient r2Weight coefficient, omega, of the proportion of the amount of electricity discarded for clean energy3Weight coefficient, ω, of ratio of clean energy capacity to η for centralized access4The weight coefficient of the power supply installed proportion with the peak regulation depth of more than 50 percent.
It is necessary to supplement that for ω mentioned above1、ω2、ω3And ω4The specific value of (a) can be set by a person skilled in the art according to actual needs, and the embodiment of the present invention is not limited.
