摘　　要：随着化石资源的不断消耗、人类环保意识的增强以及科技的不断进步,新能源的发展得到了更多的重视,分布式新能源系统也成为综合能源系统的重点研究对象。基于Roy Billinton测试系统(RBTS)模型,以长江流域某城市为例,依据该城市用电情况设计了由光伏发电装置和水力发电机组成的水光互补分布式新能源发电系统模型,以满足城市的用电需求。使用Power Factory软件对电网配置进行了优化分析,考虑实践中可能发生的情况,采用成本最小化法探讨了负荷变化情况下电力系统边际成本的变化,找到系统的利润最大点,为电网建设规模和电价的制定提供参考;以线路安全运行为目标,对可能出现的故障进行了测试和分析,确保电网整体运行的安全。With the continuous consumption of fossil fuels,our environmental protection awareness,science and technology is developing,and renewable energy has received more attention.Distributed renewable energy system have become a key object in integrated energy utilization.Based on Roy Billinton test system(RBTS)model,a hydro-solar complementary distributed power system was designed to meet the electricity demand of a city along the Yangtze River.PowerFactory software was taken to make optimized analysis on power grid configuration.Considering the practical cases,the cost minimization method is used to study the marginal cost varied with load and the maximum profit point of the power system,which can provide a reference for the government to set electricity price.And with the goal of line safety,possible faults were tested and analyzed to ensure the safety of the operation of the overall power grid.
