New energy comprehensive consumption capability evaluation method

Abstract

The invention discloses new energy comprehensive consumption capability evaluation method. The evaluation method is performed based on peak-load regulation balance in multiple periods; the evaluationmethod specifically comprises the following steps of selecting a load evening peak period, a load night valley period and a load midday peak period, and analyzing and researching regional electric power peak-load regulation balance conditions; taking the electric power peak-load regulation conditions of the load evening peak period and the load night valley period as the entry point, taking wind power installed capacity PWC as the solving object, and forming an equation set in a simultaneous manner; and taking the electric power peak-load regulation condition of the load midday peak period asthe entry point, and in a determination condition of the wind power installed capacity PWC, calculating solar energy power generation installed capacity PSC. The method is definite in ideas and clearin concepts, and can obtain the acceptable maximum scale of wind power and solar energy power generation without generating an energy abandonment phenomenon in certain power supply, power grid, load and other boundary conditions of the system, so that the scale problem in the regional new energy development can be guided effectively.

Description

technical field [0001] The invention relates to a new energy comprehensive consumption ability evaluation method based on multi-period peak regulation balance, which belongs to the field of electric power planning analysis. Background technique [0002] After nearly ten years of hard work, my country's new energy development is at the forefront of the world. While my country's new energy development has achieved absolute advantages in terms of "quantity", the "quality" of new energy development is not satisfactory, especially the increasingly severe problems of abandoning wind and light, making the issue of new energy consumption a widespread concern of the society focus. [0003] At present, a lot of work has been done on wind power accommodation at home and abroad. The basic methods basically include two types: one is based on the system balance method, based on the power balance, and determines the installed capacity of wind power through the remaining peak-shaving space;...

Problems solved by technology

[0005] One of the technical problems to be solved by the present invention is to analyze the situation that the scale of solar energy new energy power supply that can be accepted by the system cannot be effectively distinguished from the perspective of peak load balance. Determine the installed capacity of wind power during the time period and low load period, and determine the installed capacity of solar power generation on the basis of determining the scale of wind power combined with the mid-morning peak period, so as to realize the transformation of the simultaneous grid-connected scale of wind power and solar power generation into a solvable problem
