【摘要】 随着电力市场的逐步开放,需要进一步评估特定发电及负荷节点对于整个系统的影响.一种新的潮流追踪方法可实现“追踪”发电节点到负荷节点的有功及无功潮流,同时还可以评价各发电(负荷)节点对特定输电线的利用程度.提出运用潮流追踪方法,依据“谁使用,谁支付”原则,按潮流的实际状况,实现发电成本及网损在不同负荷间的合理分摊.该方法不仅可为系统运行提供有效信息,而且还可用于发电服务的收费和定价.更多还原

【Abstract】 Continuing trend toward deregulation has resulted in the need to assess what the impact of a particular generator or load is on the power system. A new method of tracing the flow of electricity in electrical networks is proposed. This method may be applied to assess how much of real and reactive power output from a particular station goes to a particular load. It also allows the assessment of contributions of individual generators or loads to individual line flows. According to the principle of “the one who uses the electricity must pay for it,” we use this method to break down of the total generation cost and loss into components to be allocated to individual loads. This method can be useful in providing additional insight into power system operation and can be used to modify existing tariffs of charging for generation services.更多还原
