ABSTRACT
It is a notable fact that all power system networks usually operate under much stressed conditions. The type of load at the distribution end decides the stress exerted on each of the power system buses and a network completely. Different load models that operate decide the conditions and boundaries for the stress levels. In power flow studies, which are performed to plan, operate, and control, it is presumed that the demands of active powers and reactive powers are to be specified as a constant value, irrespective of the voltage profile. In practice, various industrial, residential, and commercial loads that demand real and reactive powers are a function of system voltage and system frequency. Hence, load modeling has significant importance. In this chapter, characterizing, comparing, and presentation of two such load models, namely voltage-dependent loads (VDLs) and frequency-dependent loads (FDLs), are performed. Artificial intelligence has become a topic of interest as it is applied to smart utilities these days. Binary search procedure for optimal placement of thyristor-controlled series capacitor (TCSC) is studied while comparing the above-said loads. Contribution of this research work is to provide an estimation approach using binary search algorithm. The approach proposed and applied here is proven to be simple yet powerful.
