Comprehensive energy system source-load low-carbon economic dispatching method considering carbon capture system

Abstract

The invention relates to an optimal scheduling method for an electrical comprehensive energy system. Specifically, the invention relates to a comprehensive energy system source-load low-carbon economic dispatching method considering a carbon capture system. A carbon storage device is used as a pivot to connect a carbon capture power plant and an electricity-to-gas conversion device; and introducing comprehensive demand response, the electricity-gas comprehensive energy low-carbon economic dispatching method with the optimal comprehensive cost is provided, plays a very important role in promoting wind power consumption and reducing system carbon emission, and has very important practical significance and application and popularization value in improving the economical efficiency and low-carbon environmental protection performance of operation of an electricity-gas comprehensive energy system.

Description

technical field [0001] The invention relates to a low-carbon economic scheduling method for an electric-gas integrated energy system, in particular to a "source-load" low-carbon economic scheduling method for an integrated energy system considering a carbon capture system. [0002] technical background [0003] In recent years, the energy crisis and the greenhouse effect have intensified, reducing CO emissions 2 Become the core consensus and key measures to deal with global climate change. Currently, the power industry is the largest CO in China's national economy. 2 The emission sector, while facing enormous pressure to reduce emissions, also shows possible emission reduction potential. In addition, under the background of energy conservation and emission reduction and the development of low-carbon economy, renewable energy represented by wind energy has ushered in a good opportunity for development. Due to the strong intermittent and random characteristics of wind power ...

Problems solved by technology

[0006] At present, most of the research on the integrated energy system with carbon capture system is limited to the CO 2 capture to reduce carbon tax costs, but did not consider how to capture CO 2 Harnessing them and how to address the mismatch between carbon capture and power-to-gas operation cycles

In addition, most of the current research focuses on the dispatching analysis of the combination of carbon capture equipment or demand response with the traditional single energy system. Coordinated and coordinated research, as the pressure of energy conservation and emission reduction gradually increases, the feasibility and practicability of the above optimization methods will have great limitations
