摘要
鉴于经济调度中节点电价是实现有功最优分配的基础,提出了考虑发电机有功约束和输电线路有功约束的改进传统直流最优潮流的节点电价计算方法。首先,给出了不考虑发电机有功约束、考虑发电机有功约束两种情况下的经济调度节点电价计算方法及其关系;其次,给出了考虑发电机、输电线路有功约束经济调度节点电价计算方法及其关系;最后,以IEEE5节点算例进行仿真验证,表明了所提方法的有效性。
Given that the nodal price is fundamental to realizing the optimal allocation of active power in economic dispatch, an improved nodal price calculation method of DC optimal power flow which considers active power constraints of generators and transmission lines is proposed.Firstly, the calculation method of the electricity price in economic dispatch nodes is proposed either with or without generator active power constraints considered.Secondly, the calculation method of the nodal price for economic dispatch considering active power constraints of generators and transmission lines is proposed.Finally, a simulation example of IEEE5 node shows the effectiveness of the proposed method.
