Method of improving wind power consumption capability

Abstract

The invention provides a method of improving a wind power consumption capability, comprising the steps of: (1) calculating the wind abandoning power of each moment before wind power consumption; (2) setting a controllable load variation value of each moment; (3) calculating a load after demand side response; (4) calculating demand side response total benefits; (5) setting the rated power and rated capacity of an energy storage system; (6) calculating the output curve of the energy storage system at each moment; (7) calculating a wind power output curve after wind power consumption; (8) calculating the wind abandoning power of each moment after wind power consumption; (9) calculating the wind abandoning electric quantity after wind power consumption in a day; (10) calculating wind power electric field investment energy storage costs; and (11) calculating the controllable load variation value, and the energy storage system rated power and rated capacity. The method reduces wind abandoning to the maximum, increases a wind power consumption capability, and takes full advantage of wind resources.

Description

technical field [0001] The invention relates to a method, in particular to a method for improving wind power accommodation capacity. Background technique [0002] According to the national power industry statistics released by the National Energy Administration, as of the end of 2014, the cumulative grid-connected capacity of full-caliber wind power in the country has reached 95.8GW, a year-on-year increase of 25.6%. A year-on-year decrease of 120h. [0003] Since the output of wind power has the characteristics of "anti-peak regulation", and the minimum peak regulation limit of thermal power units is 50% - 60%, this makes a large amount of abandoned wind even if the thermal power units operate at the lower limit of the full output force during the low load period. Peak resources are difficult to meet the needs of wind power consumption. In order to reduce wind curtailment and improve wind power utilization, it is necessary to adopt energy storage devices and coordinate de...

Problems solved by technology

[0005] In recent years, my country's wind power installed capacity has grown rapidly, but the utilization rate of grid-connected wind power equipment is low. After large-scale wind power is connected to the grid, the problem of wind power consumption has become increasingly prominent. The serious wind curtailment status has become the primary factor restricting the development of wind power. , so there is an urgent need for a method to improve the capacity of wind power consumption
