Abstract

In recent days with the increasing demand of electrical energy the power system is expanding. With the increasing power demand a question arise that whether the existing transmission network is capable to wheel the large amount of power or not. Or what amount of power that can be transferred without any violation of constraints through the transmission network. For this purpose capability of the network must be examined carefully before any transmission of scheduled power to the consumers. The additional amount of power that can be transferred through the network over and above already committed used with out any violation of limits is called Available Transfer Capability (ATC). Thus accurate ATC calculation is very important for the system operators to avoid blackouts. In this paper ATC was calculated using RPF and PTDF-based method considering different conditions of the network i.e. generator outage, line outage etc. DC Power Flow was used and the results were compared with PowerWorldsimulator (PWS).
考虑中断的可用传输能力计算
近年来,随着电能需求的不断增加,电力系统规模不断扩大。随着电力需求的不断增长,现有的输电网络是否有能力输送大量电力的问题出现了。或者在不违反输电网络约束的情况下可以传输多少电力。为此目的,在向用户传输计划电力之前,必须仔细检查网络的能力。在不违反任何限制的情况下,可以通过网络传输的额外电量称为可用传输能力(ATC)。因此,准确的ATC计算对于系统操作员避免停电至关重要。本文在考虑发电机停运、线路停运等不同情况下,采用基于RPF和ptdf的方法计算ATC。采用直流潮流模型,并与PowerWorldsimulator (PWS)进行比较。
