Embodiment Construction

[0037] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0038] figure 1 The abscissa in the middle is the value of the load side capacity, and the ordinate is the power generation reliability index LOLE (expected value of power loss time). The arc AB in the figure is a curve that simulates the change of LOLE with the load capacity after adding wind power. The point X on the ordinate axis is the reliability level of the original system. This calculation method finds the intersection point between the original reliability level...

Abstract

The invention discloses a confidence capacity assessment method of an energy storage and generation system of wind power. The confidence capacity assessment method is applied to power transmission network planning comprising the wind power and energy storage, and can be used for calculating the confidence capacity of the specific input wind power easily and conveniently through the secant method and estimating the confidence capacity of the specially-assigned energy storage system of the wind power accurately with the strategy of binding energy storage and the wind power considered from the perspective of the confidence capacity. According to the confidence capacity assessment method, the capacity assignment problem of the energy storage and generation system of the wind power in the transmission network planning can be solved, construction of a wind power plant can be simplified as much as possible under the condition of meeting the load requirement, and important reference meaning to the transmission network planning is achieved.

Description

technical field [0001] The invention relates to a method for evaluating the confidence capacity of a wind power storage power generation system, which belongs to the field of wind power generation. Background technique [0002] With the increasing pressure of energy crisis and environmental protection, the development and utilization of new energy has been paid more and more attention. Among the currently widely used renewable energy sources, as one of the fastest-growing and most mature renewable energy generation technologies, wind power has the advantages of no pollution and short investment cycle. At present, my country's wind power installed capacity has reached 42 million KW, ranking first in the world. It is estimated that the installed capacity will reach 90 million KW in 2015 and 150 million KW in 2020. Therefore, wind power is of great significance for improving my country's energy structure and protecting the environment. [0003] However, while the development...
