摘要 大用户直购电政策的推行,会进一步压缩电力系统的调度空间,而当系统中接入大规模不可调控的风电机组时,系统的优化调度将面临更加严峻的挑战。为了分析大用户直购电对系统风电消纳能力的影响,建立了含大用户直购电的电力系统风电消纳模型。该模型在传统机组组合模型的基础上,引入了风电出力约束和可削减的直购电电量合同约束,并对目标函数进行了相应的调整。使用ARIMA模型对风速时间序列进行建模和预测,为机组组合模型提供原始数据。将10机系统扩展为40机系统,并引入1 600 MW的风电机组,分析了不同直购电电价、直购机组以及直购电规模下直购电合同对系统消纳风电能力的影响。

Abstract:The space of power system dispatching shrinks with the implement of transaction mode of direct power purchase by large consumers. Especially, the integration of large-scale uncontrollable wind power tests power system dispatching optimization to its limits. Therefore, this paper sets up a wind power consuming unit commitment model with the transaction mode of direct power purchase by large consumers to analyze its effects on the wind power consumption ability of the power system. The model adds additional constraints to the traditional unit commitment model, namely constraints of direct power purchase by large consumers whose compacts can be reduced and power of the wind turbines. The origin objective function is also modified correspondingly. Autoregressive Integrated Moving Average (ARIMA) Model is taken to model and predict the time series of wind speed, providing original data for the unit commitment model. The paper initially extends the 10 units system to 40 units system, and introduces 1 600 MW wind turbines and analyzes how the mode of direct power purchase by large consumers influences wind power consumption under different real-time price curves, units with contracts and trading power of the contracts.
Key wordsDirect power purchase by large consumers    wind power    unit commitment    consumption capacity
