An optimization strategy for wind power consumption considering multi-level market linkage

Abstract

The invention discloses a wind power consumption optimization method considering multi-level market linkage, which is characterized by comprising the following steps of: firstly, before the market opening of a spot market, executing wind power fair load, i.e., non-fluctuation basic level section clearing to correct a daily load curve, and taking a clearing result before the market opening as a data information source of the market ahead of day; Then, in the day-ahead market, the market organization members give the wind-fire clearing electric quantity and the electricity price of the current stage according to the cooperative game theory and the corrected daily load curve, and the clearing result of the day-ahead market serves as the data information reference of the day-ahead market; Andfinally, entering the intraday market, and executing the wind-fire clearing electric quantity and the electricity price at the stage through listing transaction. And market clearing results of all stages are summarized, and the clearing results are fed back to members of all stages of the market. The problem that wind power consumption is insufficient is solved, establishment and perfection of clean energy in the spot market are facilitated, and therefore the consumption rate of wind power in a short time is increased, the power purchase cost is reduced, and social welfare is increased.

Description

technical field [0001] The invention relates to the field of new energy consumption in electric power systems, in particular to an optimization strategy for wind power consumption considering multi-level market linkage. Background technique [0002] In recent years, the rapid development of China's economy has led to a sharp increase in energy demand. Driven by the country's strong policies, the development of clean energy is very rapid. Its installed capacity and grid-connected capacity rank among the top in the world, but fossil energy is mainly used However, the contradiction between economy, energy and environment is very prominent due to the low energy consumption structure, which makes the new focus of society's attention on accelerating the development process of clean energy. Taking wind power generation as an example, wind power generation poles are easily affected by weather and terrain, and wind power has corresponding fluctuations and uncertainties, which makes i...

Problems solved by technology

Taking wind power generation as an example, wind power generation poles are easily affected by weather and terrain, and wind power has corresponding fluctuations and uncertainties, which makes it difficult to accommodate wind power and the quality of wind power is low

Due to the fact that my country's current wind power participation in the market is mainly based on the guaranteed purchase of power generation, the current enthusiasm for new energy participation in the market in my country is low, and its own power generation characteristics also lead to serious wind abandonment.
