| 摘要: |
| 为实现电动汽车换电站（BSS）与微电网所有权不同时微电网运行优化，建立了微电网经济调度双层优化模型。在上层模型中，微电网调度中心是决策机构，其目标函数是微电网供电成本最小；在下层模型中，BSS运营商是决策机构，在考虑换电需求量不确定性的基础上，建立以BSS利润最大为目标函数的盒式集合鲁棒优化模型。上、下层优化模型通过微电网向BSS提供的个性化电价实现互动。采用入侵杂草算法和CPLEX软件分别对上、下层优化问题进行求解，得到微电网内部可控微电源的出力和个性化电价，实现微电网和BSS的共同利益。对某中压微电网进行算例分析，结果验证了所提模型及算法的合理性和有效性。 |

| Abstract: |
| In order to realize the operation optimization of microgrid when its ownership is distinct from that of electric vehicle BSS（Battery Swap Station），a bi-layer optimization model is built for its economic dispatch. In the upper-layer model，the microgrid dispatch centre is the decision-making body，taking the minimum power supply cost as its objective；while in the lower-layer model，the owner of BSS is the decision-making body，taking the maximum profit as its objective，which is a robust optimization model with the box set based on the consideration of battery swap demand uncertainty. The interaction between the upper-layer and lower-layer models is implemented via the particular electricity price offered by microgrid to BSS. The upper-layer and lower-layer models are solved by the invasive weed optimization algorithm and the CPLEX software respectively to obtain the output power of the controllable microsources and the particular electricity price for mutual benefit. The analytical results for an middle-voltage microgrid show the rationality and validity of the proposed model and algorithm. |
