A Review - Analysis of Power System Network Like Real and Reactive Power Flows

AC power sources are essential pieces of equipment for providing flexible and reliable power generation. The concepts of power generation and power loss can be dangerous for end users. This is especially true when it comes to talking about the different types of power quantities. This study presents a comparative study for four evolutionary computation methods to the optimal active–reactive power dispatch problem. Theoretically, there is a coupling relation between active–reactive power dispatches. However, because of high X/R ratio existing in the transmission line, the problem of active–reactive power dispatch can be decomposed into two individual sub-problems by the decoupling concept, that is, active–reactive power dispatch problems. On-line power system analysis enables to make power mode-related decision based on information available at real time. The quality of the studies and efficiency of power system operation are closely associated with the accuracy of the power system models. Accurate and quick decision based on analysis on real time data has been necessary for making operational plan under the deregulation of power system worldwide.
