Optimization of Microgrid Operation Strategies Based on Carbon Asset Graph Data

This study aims to minimize operational costs and carbon emission by systematically considering load constraints, charging and discharging constraints of energy storage equipment and carbon quota limitations. A dual layer optimization model for microgrid carbon asset operation and economic benefits is formulated. Considering carbon asset operation into outer planning model, the operation strategy for microgrid is optimized by utilizing an improved Grey Wolf algorithm. The inner demand response model improves users’ electricity consumption behavior through incentive measures. Then, the optimized load curve improves the utilization rate of new energy and it is input to the outer model. Interactive iterations between the inner and outer dual layer models are conducted until the optimal configuration and load curve of each device are reached.
