Effect of Power Electronics Control Techniques and Switching Optimization on Energy Efficiency

Abstract

The increased need of power efficient power systems in industrial, commercial as well as renewable energy systems has brought power electronics control methods and switching optimization to a strategic level in engineering. This paper measured the impact of energy saving in the professionals of the power generation and distribution market in Pakistan by power electronics control methods and switching optimization. A quantitative research design that is engineering-oriented was adopted. A purposive survey sample of 200 electrical engineers, designers of power systems and industry experts were surveyed using a structured survey instrument comprising of perceptual scales, and technical assessment indicators, which was chosen via purposive sampling based on pertinent experience in the field. Descriptive statistics were used to summarize the profile of respondents and variables. Measures of reliability and validity were measured using Cronbach alpha, Composite Reliability (CR) and Average Variance Extracted (AVE). Inter-variable relationships were analyzed using correlation analysis. The measurement model and structural relationships were tested with Structural Equation Modeling (SEM) with SmartPLS 4.0. These power electronics control techniques showed a strong positive impact on energy efficiency (beta = 0.51, p < .001), and switching optimization also had a strong positive direct impact (beta = 0.44, p < .001). This model was able to explain 62.3 percent of the variation in energy efficiency (R-squared = 0.623). These results demonstrate that both the intentional use of high-level techniques of control and organized optimization of switching parameters are key levers in the attainment of real energy efficiency gains in the power systems in Pakistan.
