Abstract :
Transmission Expansion Planning (TEP) problem refers to proposing the
optimal number and location of new transmission lines in order to satisfy operation
conditions with less investment costs. Adequacy evaluation of trial solutions is essential to
solve TEP problem. This evaluation procedure may require a considerable computational
e ort; therefore, improvement of Adequacy Evaluation Methods (AEMs) is a key to
achieve more ecient TEP solution algorithms. It is a common practice to employ
a Linear Programming (LP) called \DC operation model" to perform this evaluation,
especially in cases that generation rescheduling is considered in TEP studies. In this
paper, an AEM is proposed as an alternative with less computational e ort to perform
adequacy evaluation. In fact, the proposed AEM is applicable in TEP problems considering
generation rescheduling. The study is based on DC TEP model where electrical aspect of
the problem is modeled based on DC power
ow equations. To examine the performance of
the proposed AEM, this evaluation method is employed in a meta-heuristic TEP solution
algorithm. Such a combinatorial algorithm is then applied to di erent standard test systems
as well as practical cases. The simulation results show a promising improvement caused by
employment of the proposed AEM.
