A novel dynamic evolution algorithm to mitigate transient in large load variations

摘要

This paper presents, a controller based on dynamic evolution technique to control the three phase power inverter's output for large load changes. Proposed controller methodology is analysis and is tested on three phase inverter in MATLAB/Simulink for star and delta load with balanced and unbalanced combination. This system is also tested for lagging and leading nature of load by connecting an inductor and a capacitor in load branch. In complete operation DEC recover approximate hundred times load variation within 1ms and gives good performance against initial transients. Output power quality is good and within limit compare to IEEE 519 harmonics standard.
