| 摘要: |
| 以能源互联网为依托，研究了风能在转化利用过程中不同“能质”能量之间的等效转化关系及其对应的效益。为综合考虑负荷需求特性及供能价格因素对风能利用方式的影响，以风电利用率最大和系统运行综合效益最大化为目标，构建风能转化利用多目标优化模型；然后，采用量子行为的粒子群优化算法对模型进行优化求解；最后，在不同的供能模式下进行对比分析。算例结果表明，所提模型能够有效地提高能耗系统对风能的综合利用率及消纳能力，并取得更高的能售效益，验证了所提模型及其运行方式的有效性和可行性，为大规模风电的开发和利用提供了新的思路。 |

| Abstract: |
| The equivalent conversion relationships among different “energy qualities” during the conversion and utilization of wind energy, together with the corresponding benefits, are investigated based on the energy internet. A multi-objective optimization model of wind-energy conversion and utilization is established, which takes the maximum wind-energy utilization rate and the maximum system operational benefit as its objectives and considers comprehensively the influences of load demand and energy-supply price on the wind-energy utilization mode. The quantum-behaved particle swarm optimization algorithm is adopted to solve the model and analytic comparison is carried out among different energy-supply modes. Case study shows that the proposed optimization model improves the comprehensive wind-energy utilization rate, wind-power accommodation capability and energy-sale benefit of energy consumption system. The effectiveness and feasibility of the proposed models and operating modes are verified, providing a new concept for the large-scale development and utilization of wind energy. |
