Restructured Hydrothermal System: Slack bus Management

In order to logically represent the power system, it is necessary to develop a concept to compensate various mathematical imbalances, for which the concept of slack bus came into the picture. But when large system is considered, the overall limit of slack bus is not sufficient to compensate the imbalances. In addition to this, the practical depiction of slack bus does not hold when multiple time intervals are considered in HTS problem. In this research, the concept of slack bus is modified and improved so that it can be used for a large power system in restructured hydrothermal system. Furthermore an improved ABC algorithm, i.e. GOABC is proposed, which provides superior diversity and enhanced convergence compared to ABC algorithm.
