摘要/Abstract

摘要： 现有风电优化运行模型中鲜有涉及风电场内部机组优化的运行策略，且风电大多以“被动”参与者的身份参与系统调度，忽略了风电自身提供灵活性的可能。基于此，提出一种面向提供系统灵活性的风电场内机组优化运行方法。首先，从供给侧和负荷侧分析风电场站并网时的灵活性资源及灵活性需求，探讨了风电作为灵活性资源的可能性，建立了其灵活性模型；其次，基于风电机组的运行特性采用FCM聚类算法对其进行灵活性分类，并建立分类机组的等效虚拟电源运行模型；然后，构建面向提供系统灵活性的风电场内机组优化运行模型，该模型在得到风电场最优出力计划的同时，通过优化风电场内机组的出力计划使风电场机组的损伤最小；最后，以某风电场为例，通过修订后的IEEE标准节点测试系统验证了该方法的正确性与有效性。

Abstract: Among all existing wind power optimization operation models, only few of them apply operation strategies involving the optimization of internal units in wind farms. Moreover, most wind power units participate in the system dispatching as "passive" role, overlooking the potential capability of wind power itself to provide flexibility. With regards to this issue, this paper proposes a new method for the optimal operation of units in wind farms that can provide system flexibility. First, the authors analyze the flexible resources and flexibility requirements of wind farms from both the supply side and the load side, explore the feasibility of wind power as a flexible resource, and then establish the system flexibility model respectively. Secondly, based on their operating characteristics, the wind turbines, are classified using FCM classification algorithm in terms of their flexibilities such that the equivalent virtual power dispatch model of the units are established. Then an optimal operation model of wind farm units is constructed to provide system flexibility by which the optimal generation output plan of the wind farm is obtained while minimizing the damage to the wind farm units. Finally, taking a wind farm as an example, the correctness and effectiveness of the method is verified through the revised IEEE standard testing system.

Key words: new energy grid connection, wind power flexibility, wind turbines classification, optimized operation, virtual power
