Source-load coordinated optimization scheduling method considering green certificate and carbon transaction system

Abstract

The invention discloses a source-load coordinated optimization scheduling method considering a green certificate and a carbon transaction system. The source-load coordinated optimization scheduling method introduces a current power certificate transaction system and a carbon emission right transaction system based on the background of low-carbon power and an intelligent power grid while enabling ahigh-energy load to be included in a wind-power-containing power system optimization scheduling model. The source-load coordinated optimization scheduling method takes the maximum net income of a power generation enterprise as an optimization target, establishes a source-load coordinated optimization scheduling model considering green certificate transaction and carbon transaction, solves the established model by adopting an adaptive immune vaccine algorithm, and compares and analyzes the influence of the introduction of the carbon transaction system and the calling of the high energy load onthe system, and the results show that the source-load coordinated optimization scheduling method provided by the invention can effectively improve the green certificate yield, reduce the wind curtailment rate and promote wind power consumption, thereby reducing the average carbon emission per unit power generation amount, ensuring the net income of power generation enterprises to a certain extent, and improving the new energy utilization rate and environmental protection benefits.

Description

Technical field [0001] The invention relates to the field of optimal dispatching of new energy into the power grid in power systems, and in particular to a "source-load" coordinated optimization dispatching method that takes into account green certificates and carbon trading systems. Background technique [0002] With the development of social economy, the demand for fossil fuels is increasing, and environmental problems such as environmental pollution and climate change caused by fossil fuel consumption have become increasingly prominent. Global warming is one of the most serious environmental problems of this century. How to reduce and control CO 2 Emissions have become the focus of governments around the world. Electric Power IndustryCO 2 Emissions account for a high proportion of the country's total emissions. The urgent demand for low-carbon electricity has led the government to reduce CO in the power industry by vigorously developing renewable energy power generation...

Problems solved by technology

At the same time, large-scale wind power bases generally have difficulties such as limited regional consumption and narrow delivery channels, and existing solutions such as pumped storage and energy storage batteries that can effectively improve the peak-shaving capacity of the system have application restrictions to varying degrees.
