全可再生能源多能互补系统优化配置与运行探索

Investigating this policy’s impact on such systems is particularly important. In this study，the capacity allocation and dispatching optimization model based on partial grid power supply and“electricity sales in the partition wall”. The impact of grid power supply and“electricity sales in the partition wall”on energy storage ratio，economic efficiency，and carbon emission parameters are examined. The results indicate that as the price of electricity sold in the partition wall increases，the system’s operating cost and battery capacity decrease，with the battery unit capacity stabilizing after the price reaches 0.33 Yuan∕kWh. The system’s operating strategy no longer changes after the electricity price reaches 0.37 Yuan∕kWh. Compared with a traditional system without "electricity sales in the partition wall，" the park multi-energy complementary system is 25.9% more cost-effective，with a 37.8% reduction in annual operating costs and a decrease in carbon emission intensity from 76.9 kgCO2（∕ m²·a）to 52.3
