Embodiment Construction

[0038] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and technical solutions.

[0039] Based on the output distribution function of the wind and solar power station cluster, the output of the wind and solar power station cluster is converted into a series of continuous output intervals. The specific steps are as follows:

[0040] Step1. According to the output probability distribution function of the wind and solar power station cluster in each period, the output of the wind and solar power station cluster in each period corresponding to the α quantile is obtained:

[0041]

[0042] where: Represents the output of cluster i in each period when the quantile is α; Represents the output of cluster i at time t when the quantile is α, and the unit is MW; represents the output probability distribution function of cluster i at time t;

[0043] Step2. Take a series of quantiles {0=α 1 2 …m …M+1 =1...

Abstract

The invention belongs to the field of power system dispatching, and provides a method for quantifying the flexibility demand of a wind-solar-water multi-energy complementary system and a coordinated optimization method. First, a method for quantifying the demand for flexibility considering the uncertainty of wind-solar output is constructed, and quantile points are used to quantify the wind-solar output interval. Divide and generate output scenario sets, and then calculate the flexibility requirements in each scenario; based on the quantitative indicators of flexibility requirements, build a water-solar hybrid optimization scheduling model that considers the lack of system flexibility with the smallest expectation, so as to realize the optimal calculation of water-solar hybrid. Relying on the actual wind-solar-water complementary system of Yunnan Power Grid, model verification is carried out for different new energy access ratios. The results show that the method of the present invention can provide multi-type power supply complementary operation scheduling schemes under different conditions, effectively meet the flexibility requirements of the system, reduce Abandon electricity and improve the consumption level of clean energy.

Description

technical field [0001] The invention relates to the field of power system scheduling, in particular to a method for quantifying and coordinating optimization of flexibility requirements of a wind-solar-water multi-energy complementary system. technical background [0002] For systems with a small scale of wind and solar power, the reserve capacity reservation method can effectively deal with uncertainties such as power and load. However, as the proportion of wind and solar in the system continues to increase, affected by the uncertainty and large fluctuations in its power generation output, the previous reserve capacity method may significantly increase the system cost. The core problem is how to accurately quantify and absorb the uncertainty of wind and solar Flexibility requirements for power generation. At present, some results have been carried out to carry out research in this area, and some evaluation indicators have been proposed, which can be divided into three cate...
