Low-Carbon Optimal Operation Strategy of Integrated Energy System Considering Generalized Energy Storage and LCA Carbon Emission

doi:10.16183/j.cnki.jsjtu.2022.350

Abstract

Abstract:

Integrated energy system (IES) is the key to achieve the “dual carbon goals” in face of the current energy industry transformation and low-carbon development. In order to improve the carbon emission reduction capacity of the IES, it is necessary to make full use of the load resources on the demand side and the generalized energy storage resources such as traditional energy storage equipment to participate in the optimization of the IES. First, an IES optimization operation model considering renewable energy, energy conversion equipment, generalized energy storage equipment, and energy market transaction is established. Then, the life cycle assessment (LCA) method is used to calculate the carbon emission of the whole process of energy cycle and equipment cycle in the IES, and the carbon emission cost is included in the total cost of the system. The results of simulation experiments show that the proposed model is not only conducive to reducing the total scheduling cost of the IES, but also able to reduce the carbon emissions of the system and effectively promote the low-carbon development of the IES.

Key words: generalized energy storage, carbon emissions, integrated energy system (IES), optimized operation, life cycle assessment (LCA)
