Embodiment Construction

[0037]The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0038]The following takes the embodiment of the present invention as an example to illustrate the steps of the method for evaluating the new energy consumption capacity of the present invention.

[0039]Step one is to establish a framework for analysis of technical flexibility resources.

[0040]The technical flexibility resources include flexibility resources on the power supply side, flexibility resources on the grid side, flexibility resources on the load side, and flexibility resources on the energy storage side.

[0041]The process of establishing the technical flexibility resource framework system is to collect technical flexibility resources, and classify the collected technical flexibility resources according to the horizontal distribution position and the vertical time scale. The horizontal distribution position includes the power supply side, the grid side, and the ...

Abstract

The invention discloses a new energy consumption capability evaluation method based on a technology and market flexibility unified framework. The method comprises the following steps: firstly, establishing a time scale-based technical flexibility resource framework of a power supply side, a net rack side, a load side and an energy storage side of a regional power system; secondly, establishing a market flexibility mechanism framework considering a spot market, a wind-fire power generation right transaction, a cross-provincial transaction and a peak regulation auxiliary service market; then comprehensively considering technical flexibility resources and a market flexibility mechanism, and establishing a power system flexibility unified framework for promoting new energy consumption; and finally, quantitatively evaluating the new energy consumption capacity through the new energy power abandoning rate by utilizing the framework, and guiding the regional power system to perform flexible resource selection according to an evaluation result, thereby continuously updating the iterative regional power system to optimize the operation.

Description

Technical field[0001]The invention relates to a method for evaluating new energy consumption capacity.Background technique[0002]At present, accelerating the development of new energy has become the universal consensus and concerted action of the international community to promote the energy revolution and respond to global climate change. China's new energy development has been at the forefront of the world. As of the end of 2016, the installed scale of wind power and solar power generation both ranked first in the world. With the accelerated development of new energy, the phenomenon of abandoning wind and light has appeared in some areas of China, and the contradiction of new energy consumption has gradually emerged. Due to the characteristics of resource endowments, power system conditions, and market system and mechanism issues, large-scale development and utilization of new energy faces great challenges. With the deepening of power market reform, my country has also adopted a se...
