Abstract:

With the growing demands for energy supply and environmental protection, energy storage operations and charging strategies need to align with the carbon peaking and carbon neutrality goals. This paper proposed a method for optimizing energy storage profits considering carbon emission constraints and market participation, and defined an unified data model for both the physical grid and optimization computations. The proposed method incorporated the carbon emissions limits during the charging/discharging process of energy storage to meet the requirements of environmental regulations and carbon reduction standards, and included various constraints related to storage configuration and management, such as storage capacity, charging/discharging power limits, and energy exchange balance within the system. Based on the real data of a feeder provided by a provincial power supply company, the maximized energy storage profits were calculated using the proposed method.

Key words: energy storage, market price, carbon emissions, optimization model, data model.
