摘要
输电网与配电网规划问题均是电力系统规划中的经典问题,而将二者协同考虑能够在投资预算总额固定的情况下获得整体更优的规划方案。为解决输配电网协调规划组合爆炸、求解困难的问题,提出基于配网规划等值曲线的输配电网分层协调规划方法。各配电网分别求解不同新增项目数量下的最优规划方案和最大净收益,得到配网规划等值曲线;将其嵌入输电网规划模型的目标函数即可得到输配电网协调规划方案。该方法可以减少模型中的决策变量数量,提升求解效率。基于Garver’s 6节点输电系统和REDS-135节点配电系统构造的输配电网规划算例验证了所提方法的有效性。
Transmission network planning and distribution network planning are all classical problems in power system.The coordination programing of these networks will lead to global optimal planning solution with the premise of a prescribed investment budget.In order to tackle the issue of combinatorial explosion in the coordinated planning,a bi-level calculation method based on the project-net revenue curve of distribution network is proposed.By solving the distribution network planning model repeatedly,project-net revenue curve is obtained and passed to the transmission network expansion model.This method significantly reduces the number of integer variables in the coordinated planning problem.In case studies,transmission&distribution testbed based on the modified Garver’s 6-bus system and the REDS-135 system verifies the effectiveness of the proposed method.
