摘　　要：建立基于联络线交换计划、检修计划、系统负荷预测曲线、母线负荷预测曲线、网络拓扑等约束信息的光伏发电接纳能力评估模型。采用单纯形方法求解光伏发电最大接纳能力,实现日前和日内光伏发电接纳能力的连续过程整体优化。结合实际电网,分析电网网络拓扑、电源出力等因素变化引起光伏发电接纳能力改变情况,验证了建立光伏发电接纳能力评估模型。Based on the several information such as tie line switching plan, maintenance and overhaul schedule, the system load forecast curve, the bus load forecast curve, the power grid topology and other information, a model to evaluate accommodation capacity for photovohaic power generation is built in this paper, and the maximum accommodation capacity is obtained by simplex method, realizing the whole optimization of continuous photovoltaic power accommodation process before days and in a few days. In end, taking an actual power grid as example, by analyzing the change of photovoltaic power generation capacity caused by a few factors such as grid topology, source output and other factors, a validation on the above model is given.
