摘要:

为了最大程度消纳风电及激励风电场改善并网特性，提出了一种考虑风电并网友好性的日前分层调度计划模型。上层调度模型中，通过风电和常规机组的协调调度，实现系统综合成本最小的目标。下层调度模型中，建立风电友好性评估模型对风电场并网友好性予以评估。以风电功率预测信息及上层调度模型的风电出力计划等作为约束，制定各风电场的日前调度出力计划。最后通过在IEEE 30节点系统进行算例仿真，验证了该方法的有效性。

Abstract:

A day-ahead hierarchical dispatching model considering friendliness of wind power is proposed to maximize accommodation of wind power and encourage wind farms to improve grid integration characteristics. In the upper-layer dispatching model, the minimum comprehensive cost of the system is achieved through coordinating dispatching of wind farms and conventional units. In the lower-layer dispatching model, the wind power friendliness evaluation system is established to evaluate the friendliness of wind farms. With prediction information and upper-layer dispatching model dispatching plan of wind power as constraints, a day-ahead dispatching plan of every wind farm is formulated. Simulations on an IEEE 30-bus system demonstrate the effectiveness of the proposed methodology.
