Market trading method based on flexible consumption of abandoned wind power at load side

Abstract

The invention belongs to the technical field of power system peak regulation, and in particular relates to a market transaction method for flexibly consuming and curtailing wind energy on the load side. Including calculating the proportion of low-valley wind power capacity in wind power installed capacity through load forecasting, start-up mode and incoming wind forecasting, and comparing the corresponding relationship between the low-valley wind power capacity of the power grid and the curtailed wind power, and obtaining the curtailed wind power for the next day through conversion; obtain local energy Satisfy the loads of flexible consumption of abandoned wind power; establish a model for each load to consume abandoned wind power during the low power consumption period; find the optimal time for each local load to consume the abandoned wind power during the low power consumption period, and superimpose the load power of each period, Obtain the function of the optimized electricity consumption and abandonment of wind; according to the newly obtained curve of electricity consumption and abandonment of wind, calculate the maximum consumption of electricity. The invention solves the problem that a large amount of abandoned wind cannot meet the requirement of peak shaving even after rational distribution of output on the power generation side, realizes flexible scheduling on the load side to absorb the abandoned wind power, and greatly improves the efficiency and economy of wind power generation.

Description

technical field [0001] The invention belongs to the technical field of power system peak regulation, and in particular relates to a market transaction method for flexibly consuming and curtailing wind energy on the load side. Background technique [0002] my country has a vast territory and is rich in wind resources. According to the research data of the National Meteorological Administration, the amount of wind energy that can be developed in my country is 253 million million hours. However, the distribution of wind resources is relatively uneven, mainly in the northeast, north, northwest and some coastal areas. Because of the characteristics of the distribution of wind resources above, my country adopts large-scale centralized development of wind power. Not only that, in order to encourage the development of wind power, the state has promulgated a series of policies and regulations in recent years. In 2006, my country promulgated the "Renewable Energy Law" and the "Ener...

Problems solved by technology

[0005] In order to overcome the problem in the prior art that the overall peak-shaving capability of the entire system is greatly reduced due to the heating needs of the thermal power units in winter, and the wind curtailment is more serious during the low-valley period of the power grid load, the present invention provides a load-side-based flexible consumption Market transaction method of receiving and curtailing wind power
