Clean energy cross-regional consumption feasibility assessment method

Abstract

The invention discloses a feasibility evaluation method for clean energy cross-regional consumption. The method comprises the steps of obtaining a correlation coefficient between a wind power output characteristic of a sending end in clean energy cross-regional consumption and a load characteristic of a receiving end in clean energy cross-regional consumption according to historical operation data of a power grid; obtaining a clean energy abandoned electricity quantity proportion of the sending end and a clean energy capacity proportion of centralized access in the sending end; obtaining a comprehensive evaluation coefficient of clean energy cross-regional consumption according to the correlation coefficient, the clean energy abandoned electric quantity proportion and the centralized access clean energy capacity proportion; obtaining the theoretical delivery demand capacity of the sending end through analog calculation according to the comprehensive evaluation coefficient; and obtaining a scheduling period in which the power generation plan needs to be optimized. The feasibility evaluation method for cross-regional consumption of clean energy provided by the invention has the advantages of carrying out evaluation in the economic aspect and avoiding waste.

Description

technical field [0001] The invention relates to a feasibility evaluation method for cross-regional consumption of clean energy, which belongs to the technical field of power grids. Background technique [0002] As people's life is becoming more and more dependent on electricity, the consumption of electricity is also increasing. At present, renewable energy power generation occupies a certain proportion in the grid. [0003] Clean energy, that is, green energy, refers to energy that does not emit pollutants and can be directly used for production and life, including nuclear energy and "renewable energy." Build a unified national power market and promote the optimal allocation of clean energy such as hydropower across the country. It is beneficial to build a clean, low-carbon, safe and efficient energy system, which is conducive to the prevention and control of air pollution and the construction of a beautiful China. [0004] However, in many areas with large electricity de...

Problems solved by technology

[0004] However, in many areas with large electricity demand and concentrated grid load, their clean energy resources are relatively scarce, which cannot meet the local electricity demand. At the same time, many areas with relatively small electricity demand have clean energy resources. It is relatively rich, which makes it difficult to absorb local clean energy, and then leads to the problem of waste of local clean energy
