| 摘要: |
| 直流跨区输电成为当前新能源发电快速发展背景下新能源电力消纳和资源优化配置的有效手段之一，但风力发电的不确定性也给跨区直流电网的决策调度带来困难。利用模糊参数对风电的不确定性进行描述，以可信性测度为理论依据，形成模糊机会约束，建立了计及风电预测不确定性的跨区域日前调度模型。求解时将模糊机会约束清晰化，降低了模型的求解难度，并使用混合整数线性规划方法求解。算例分析表明，相比传统的确定性模型，该方法更能反映风电预测不确定性对直流跨区输电决策的影响，验证了该模型的有效性。 |

| Abstract: |
| DC inter-regional power transmission has become one of the effective means for new energy power consumption and resource optimization against the background of rapid development of new energy power generation. However, the uncertainty of wind power generation also brings difficulties to the decision scheduling of a cross-area DC power grid. In this paper, fuzzy parameters are used to describe the uncertainty of wind power, and fuzzy chance constraints are formed on the basis of plausibility measurement to establish an inter-regional day-ahead scheduling model that takes into account the uncertainty of wind power prediction. The fuzzy chance constraint is clarified to reduce the difficulty of solving the model, and the model is solved by a mixed-integer linear planning method. The analysis of a case shows that the method in the paper better reflects the influence of wind power forecast uncertainty on the DC inter-regional transmission decision than the traditional deterministic model. This verifies the validity of the model.
