摘要
针对新型电力系统不确定性显著增加的问题,提出一种考虑场景时序相关性的输电扩展规划模型。采用场景的时间序列表征不确定性,考虑火电机组时序约束,模拟电力系统未来运行。为更加聚焦规划方案的选择,采用分层目标函数分离投资成本和运行成本。为降低模型的计算复杂性,提出循环优化建模方法来求解模型。将所提模型和非时序规划模型应用于Garver’s6节点系统、IEEE 24节点系统和中国西北38节点系统进行比较,结果表明,所提模型可得出更接近实际运行的规划结果。
Aiming at the problem of significant increase of uncertainty in new type power system,a transmission expansion planning model considering scenario temporal correlation is proposed.The scenario temporal sequence is adopted to represent the uncertainty,and future power system operation is simulated considering the temporal constraints of thermal power units.In order to better focus on the selection of planning scheme,the hierarchical objective function is used to separate the investment cost and operating cost.In order to reduce the model computational complexity,a loop optimization modeling method is proposed to solve the model.The proposed model and non-temporal planning model are applied to Garver’s 6-bus system,IEEE 24-bus system,and Northwest China 38-bus system for comparison,and the results show that the proposed model can obtain more realistic planning results.
