【摘要】 联营体模式、双边交易模式和两者的混合模式是三种典型的电力市场交易模式。不同的电力市场交易模式对网损分摊方法的选择有着重要的影响。首先,对不同网损分摊方法的基本原理、模型算法及其特点进行了阐述,着重指出了潮流跟踪法适用于联营体模式,而边际网损系数法适用于双边交易模式和混合模式。最后,对某2243个节点系统夏季峰荷、腰荷和谷荷三个典型系统运行方式进行了实例计算,验证了方法的可行性和有效性。更多还原

【Abstract】 Pool model,bilateral model and their hybrid model are three typical power market transaction models. The power market transaction models play a key role in selecting loss alloca-tion method. The basic principles and mathematical models of different loss allocation methods are discussed. It is mainly pointed out that the power flow tracing method is especially suitable for pool model,while the marginal loss coefficient method is useful for bilateral and hybrid models. The computation results of three typical base cases of a practical 2 243-node transmission system demonstrate that the two suggested loss allocation methods are feasible and effective.
