风电动态接纳区间与备用的协调优化

消纳问题是制约大规模并网风电高效利用的瓶颈，而调度决策是消纳并网风电的核心问题。根据风电功率预测误差概率分布及功率波动概率分布与备用需求变化间的关联关系，建立并网风电的备用需求模型，定量的表示风电出力的不确定性。在调度决策中，将风电视为可“主动”参与调度的电源，构建了风电动态接纳区间与备用协调优化的调度模型。模型计及了风电的不确定性，通过制定合理的风电并网容量区间计划和机组出力计划，在保证系统运行安全性的同时兼顾了系统运行的经济性，为含大规模并网风电系统最大程度地合理消纳风电提供了方法。

Coordinated Optimal of Wind Power Dynamic Acceptance Interval and Reserve

The consumption problem is the bottleneck of utilizing large-scale of wind power, and dispatch decisions are the cores to absorb wind power. The paper establishes reserve requirement model of integrated wind power based on the relationship between the probability distribution of wind power forecasting error and power fluctuation and reserve requirement variations. Thus the uncertainty of wind power output is quantified. In dispatch decisions, wind power is considered as sources which can actively participate in the dispatch and the reserve-coordinated-optimization dispatch model of the wind power dynamic acceptance interval is constructed. The proposed model considers the uncertainty of wind power and makes reasonable integrated wind power capacity interval schedule and unit commitment schedule. This ensures the security of power system while meeting the economy of system operation and provides reasonable methods to absorb wind power in a maximum degree in power system with large-scale of wind power.
