VA Loading Optimization of a Converter Using the Rao Algorithm for Maximum Utilization of the Unified Power Quality Conditioner
Main Article Content
Abstract
In a modern power system, the unified power quality conditioner (UPQC) is considered to be the most effective device for mitigating power quality problems. The use of the dynamic voltage restorer (DVR) for active-reactive power-sharing reduces the loading on the UPQC in all operating conditions, leading to better system efficiency and reliability. The VA loading of the DVC can be controlled by maintaining a proper angle between load and source voltage. In this paper, Rao algorithms are proposed to determine the optimal VA loading of the UPQC using the variable phase angle control method. The primary objective of this study is to determine the optimum angle at which the VA loading of the UPQC is minimum without negotiating the compensation capabilities. To illustrate the effectiveness of the proposed methodology, the results are compared to those for JAYA optimization. This research work will help in the development of an efficient, instantaneous VA loading-based control approach for the UPQC.
