【摘要】：传统潮流追踪在节点计算线路分摊时使用了比例分摊假设,所建立的模型一般为代数模型。以有功网络流为对象建立了有功潮流追踪数学优化模型。模型放松了比例分摊假设,从潮流追踪求解空间角度,建立了潮流追踪物理属性约束和决策约束,拓展了有功潮流追踪的范围,具有广泛的应用前景。通过负荷节点电价和电价竞争力2个应用案例进行了说明。应用于负荷节点电价计算时,以方差最小,体现公平地共享输电网,并使用简单算例进行了验证。应用于电价竞争力计算时,探索了各负荷电价竞争力的关系,提供了负荷电价竞争力更多的信息,最后使用实例验证潮流追踪对负荷之间电价竞争力的影响。
[Abstract]:In the traditional power flow tracing, the proportional allocation assumption is used in the node calculation line allocation, and the established model is generally algebraic model. A mathematical optimization model for active power flow tracking is established. The model loosens the assumption of proportional allocation and establishes the physical attribute constraints and decision constraints of power flow tracing from the point of view of power flow tracing solution space. It expands the range of active power flow tracing and has a wide application prospect. Through the load node electricity price and electricity price competitiveness two application cases were explained. When applied to the calculation of load node electricity price, the variance is minimum, which reflects the fair sharing of transmission network, and a simple example is used to verify it. When applied to the calculation of electricity price competitiveness, the relationship between each load price competitiveness is explored, and more information about load price competitiveness is provided. Finally, an example is used to verify the influence of power flow tracing on the power price competitiveness between loads.
