Wind-solar-storage complementary system demand response strategy based on correlation analysis

Abstract

A wind-solar-storage complementary system demand response strategy based on correlation analysis comprises the following steps: selecting a load tracking coefficient to analyze the correlation betweenvarious power supply signals and loads in a wind-solar-storage complementary system; establishing a demand response basic theoretical model based on a demand price elasticity theory; establishing a wind-solar-storage complementary demand response optimization model based on correlation analysis; and solving the established wind-solar-storage complementary demand response optimization model by adopting a particle swarm algorithm. An electricity price strategy is used as a random particle, and an optimal real-time electricity price strategy is solved by continuously optimizing the indexes including the load peak-valley difference, the average electricity price difference and the load tracking coefficient after the demand response, so that a load curve is matched with a wind-solar-storage complementary power generation curve to the maximum extent, and the purpose of fully consuming the output of the wind power on the power generation side is achieved. According to the invention, full consumption of new energy on the power generation side can be realized.

technical field

[0001] The invention relates to the technical field of demand response for a wind-solar-storage complementary power generation system, in particular to a demand response strategy for a wind-solar-storage complementary system based on correlation analysis. Background technique

[0002] The rapid development of clean energy has eased the increasingly severe environmental problems and energy crisis, but it has also brought many problems. New energy sources such as wind power and photovoltaics are easily affected by the external environment, resulting in fluctuations and randomness in their power generation, which poses a huge challenge to the consumption of clean energy.

[0003] Aiming at the technology of multi-energy complementary system to promote new energy consumption, the current research is mainly to carry out scheduling optimization on the side of multi-energy complementary joint system to overcome the uncertainty of new energy power generation, and use...

Embodiment Construction

[0026] The demand response strategy of the wind-solar-storage hybrid system based on correlation analysis firstly analyzes the correlation between the multi-energy complementary system and the load, and verifies the ability of the complementary system to track the load. Secondly, according to the various factors that have the greatest impact on users, and aiming at the maximum benefit of users, the basic model of demand response is improved. Finally, in the optimization model of demand response, a method of combining correlation analysis and demand response strategy is proposed to formulate an appropriate electricity price strategy. Guide users to actively change the power consumption pattern, and use the correlation analysis index load tracking coefficient to judge the matching degree between the power generation complementary system and the load. It is hoped that the load curve can adapt to the power generation curve, and make the load curve approach the power generation curve...
