摘要 传统的经济调度和市场环境下的调度是电力系统的2个典型调度模式。然而,完全的经济调度和完全的市场调度模式都存在一定优缺点。以2种主要调度模式为基础,研究了计及电力自由交易的混合调度模式,并提出了混合调度的数学模型。该模型将电力空间分为参与竞争和不参与竞争2部分,参与竞争的部分电力不受电力网络和市场交易模式的限制,是完全竞争的,采用市场调度的模式;而不参与竞争的部分电力承担调节线路潮流和网损分配的任务,采用经济调度的模式。通过IEEE-30节点系统分析了混合调度模式下不同电力自由交易比例对电力系统运行的影响,并在电力自由交易的基础上确定了最优的交易比例。 Traditional economic dispatching and market dispatching are two typical dispatching models in power system.However,there are some merits and demerits in the full eco-nomic dispatching and full market dispatching. In this paper,a hybrid dispatching model considering the free electricity tran-saction based on these two kinds of dispatching models is studied,and the mathematic model of the hybrid dispatching is developed. In the proposed model,the power is divided into two parts: the power participating in the market competition and the power not participating in the market competition. The former is fully competitive,which employs the market dispat-ching model while the latter is responsible for the adjustment of the power flow and the allocation of the network losses,which employs the economic dispatching model. Finally,the influence of different transaction ratios on the power system operation using the hybrid dispatching model is analyzed on the IEEE-30 bus system,and the optimal transaction ratio is determined.
