A new perspective in power loss reduction of ninety two buses integrated D-STATCOM

The electrical energy demand continues to increase along with the rapid development of technology and population growth. Fulfilling the electricity supply is a challenge for the operation of the electric power system since the construction of distribution and transmission infrastructures require large costs and such long time process. The complexity of the power distribution system itself may affect the voltage deviation and power loss parameters. The more complex of the distribution system was configured the more critical impacts on those disturbance parameters encountered entire the power network. The main contribution in this research is exploring on 99 bus context with D-STATCOM injection to increase the voltage profile, reducing the total active power loss and optimal size of D-STATCOM using the Optimal Power Flow (OPF) method for load flow analysis and Particle Swarm Optimization (PSO) in optimizing total loss active power and size of D-STATCOM on a radial distribution network system. This study aims to improve the distribution network performance in terms of the voltage profile, the total active power loss through optimal D-STATCOM placement. Optimization uses the Optimal Power Flow (OPF) method based on Particle Swarm Optimization (PSO). The proposed algorithm is calculated numerically for the North Makassar distribution system with ninety two buses included a network pattern open-loop radial configuration and the total load reaches 4.914 MW. The optimized computation algorithm result a minimum voltage profile of up to 0.73%, an average voltage profile up 0.8% or 4kV and a minimum total active power loss around 10.53%.
