Abstract
With the aggravation of environmental problems, countries are more and more aware of the importance of protecting the environment. In 2020, China proposed the goal of “double carbon”. As the main carbon emission industry, the energy industry will become the main battlefield. Therefore, whether the power industry can achieve low-carbon electricity and promote the accommodation of new energy will be the key to achieving carbon neutrality. Under the new background, power grid dispatching should not only consider a single economic benefit, which will lead to a large number of wind and solar curtailments, but also take into account environmental benefits and reduce CO2 emissions. In this paper, an optimal dispatching model of an Integrated Energy System(IES) is established, and CCS is added to CHP units to capture CO2 produced by CHP and send it to P2G. Aiming at the total cost optimization, carbon trading mechanism, wind curtailment cost, and solar curtailment cost are added in the model to ensure the environmental benefits in operation.
