| 摘要: |
| 综合能源系统通过多能互补与相关市场机制提升了能源利用效率的同时也引入了更多的风险因素，合理的负荷裕度是综合能源系统安全经济运行的重要保障。基于储能对综合能源系统负荷裕度的有利作用，建立了考虑负荷裕度的综合能源系统储能双层优化配置模型。其中下层模型利用储能对综合能源系统负荷裕度均衡度进行优化，而上层模型则结合负荷裕度进行储能容量优化配置，实现了社会综合成本最小化。最后，结合实际算例验证了所提优化方案的有效性。结果表明双层优化模型在实现储能容量优化配置的同时，也优化了其充、放能计划，最终实现了综合能源系统中负荷裕度的有效均衡，提高了综合能源系统应对负荷波动的能力和运行的经济性。 |

| Abstract: |
| The integrated energy system is conducive to the improvement of energy utilization efficiency through multi-energy complementation and relevant market mechanisms, and yet it introduces more risk factors. Therefore, it is necessary to reserve certain load margin to ensure the safe and economic operation of integrated energy system. Based on the positive effects of energy storage on load margin of integrated energy system, the bi-level optimal allocation model of energy storage in integrated energy system considering load margin is built, in which the equilibrium of load margin of integrated energy system is optimized with the participation of energy storage in the lower-layer model, while the optimal allocation of energy storage capacity combined with load margin is provided in the upper-layer model, thus minimizing the social comprehensive cost. Finally, the effectiveness of the proposed optimization scheme is verified by the actual case. And the results show that the bi-level optimal model realizes the optimal allocation of energy storage capacity, as well as optimizes its charging and discharging strategies, as a result realizing the effective equilibrium of load margin in the integrated energy system, improving its ability to cope with load fluctuations and operation economy. |
