Determination of location and capacity of distributed generations with reconfiguration in distribution systems for power quality improvement

The use of non-linear loads and the integration renewable energy in electricity network can cause power quality problems, especially harmonic distortion. It is a challenge operation design radial distribution system. This happen because harmonics that exceed limit interference to equipment systems. study will discuss determination optimal location capacity distributed generation (DG) reconfiguration system improve electric power, suppression distribution. combines DG using particle swarm optimization method. In addition, this research method implemented Bandar Lampung City by considering effect nonlinear quality, inverter-based type used considers value source when placed. combination proposed methods provides an solution. Increased efficiency reducing losses up 81.17% %total distortion voltage (THDv) below allowable limit.
