冷、热能只需满足阶段性平衡，而电能则需满足实时平衡。为了提升风电的利用水平和降低风电随机性对电网的影响，提出风电以制热方式和供电方式参与冷热电联供系统(CCHP)供能的供热模式及供电模式。构建并分析风电供能模式控制方法，并对2种供能模式分别建立以包含燃料成本和购电成本的系统运行成本为目标函数的优化模型。考虑风电出力预测偏差，采用α-超分位数方法刻画各随机目标函数，进而建立相应的随机优化模型。通过算例分析风电不同供能模式下的经济效益；研究不同置信水平对系统运行成本的影响。仿真结果为风电供能模式的选择提供了依据；该研究可为智能电网背景下可再生能源的高效合理利用提供新思路。

Cold,heat j ust need to meet periodically balance and power need to meet real-time bal-ance.In order to enhance the utilization of wind energy and reduce the impact of wind random-ness,wind power access to combined cooling heating and power (CCHP)system was proposed in this paper.The wind power was introduced into CCHP system in two ways,that is,heating and power supply,which respectively related to the heating mode and the power mode of CCHP sys-tem.The wind supply mode control system were constructed and analyzed.In order to obtain the decision information for the two kinds of energy supply patterns,the optimization models were established,which utilized system operation costs including fuel costs and purchasing cost as the obj ective functions.Considering prediction bias of wind power output,the random target func-tions were characterized usingα-super quantile method,and the corresponding stochastic optimi-zation models were thus established.By simulation,the economic benefits of the system was ana-lyzed in different energy supply modes,and the influence of system operation cost in different confidence levels was researched.The simulation results provided the basis for the selection of wind power supply modes.This paper provided new ideas for renewable energy development in background of smart grid.
