Application of static VAR compensator (SVC) for improving power quality of grid connected solar energy

Abstract

The green/renewable energies are being developed rapidly worldwide. Promoting renewable energies has benefits not only for the environment but also for the economic conditions of the country. The integration of renewable energy sources into power systems is a key perception of smart grids. Remarkable challenges affecting the system of integration include voltage instability, frequency instability, and general power quality. Real power drop and voltage divergence minimization are measures of voltage security of power system grids. To control system voltages, recover transient stability, upsurge transmission capacity, etc. the SVC‟s are suitable. The work recommends the optimal usage of the SVC in the enhancement of the voltage stability. The challenging of voltage collapse has been expressed as an optimization problem based on the process of particle swarm optimization (PSO) technique. This technique is applied in the study of voltage stability and power losses of the power system. The optimal introduction of SVC with particle swarm optimization technique presented a noticeable enhancement in the voltage stability with a comparatively small number of iterations and particles, therefore with a practical computational effort. The success of the projected algorithm is confirmed on IEEE-14 Bus standard test system. The proposed optimization method proved to be more effective and efficient in voltage stability and power loss reduction in the PV grid connected system.
