Optimal Location and Size of Inverter-Based Distributed Generation Considering Power Loss Reduction, Voltage Profile Improvement and Power Quality Preservation

This paper addresses optimal allocation and sizing of inverter-based Distributed Generation (DG) with the aim of reducing power loss, enhancing voltage profile and preserving power quality of radial distribution network. Problem is formulated as Mixed-Integer Non-Linear Programming (MINLP), and is solved using BONMIN solver in General Algebraic Modeling Systems (GAMS) environment. The proposed approach is evaluated on IEEE 69-bus test system, considering non-sinusoidal operating condition. Both single-objective and multi-objective optimization of loss and voltage deviation is considered, while analyzing impact of inverter-based DGs on Total Harmonic Distortion (THD)
