摘　　要：在全球消耗的能源中,相较于化石能源发电,利用风电和光电等新能源发电有利于能源安全和社会可持续发展.由于风力发电和太阳能发电具有区域性、间歇性、随机性和难以预测性等特点,大规模风电、光电并网对电力系统整体调度带来严重挑战.本文在中长期风电接纳能力评估模型的基础上,对目标函数和区域间联络线进行了优化,并加入了光伏机组出力约束.本系统在某省和地区进行了实际应用,通过可视化图表展示辅助该省电网电力系统决策发电计划以及机组检修安排,减少新能源弃电现象的发生,对电力系统实际调控及规划提供有效的指导.Compared with fossil energy power generation,the use of new energy such as wind power and photovoltaic power generation is conducive to energy security and social sustainable development.However,large-scale wind and photovoltaic power in national grid are seriously challenged by the overall dispatch of the power system,due to the regional,intermittent,random and unpredictable of wind and light.This study optimizes the objective function and the inter-regional tie-lines of the mid-to-long-term wind power acceptance capacity assessment model,and adds photovoltaic unit output constraints.The system has been practically applied in a province and a region,assisting the grid power system to determine power generation plans and unit maintenance arrangements.It can reduce the occurrence of new energy abandonment,and provide effective guidance for the actual dispatch and planning of power systems through visualized results.
