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%.

This paper describes the modelling and simulation of distribution static compensator (D-STATCOM) focused with effect of DC capacitor size and voltage regulation. Different capacitor values have been investigated to reduce the load ripple voltage during the charging and discharging of the capacitor. The optimum capacitor valuse has been determined to obtained the lowest ripple voltage within the rage of 8%. Capacitive and inductive mode of D-STATCOM operation have been also investigated and obtained results proved that the capability of the D-STATCOM in regulating the system voltage is near to the rated value of 1.0 p.u.

The sensitive industrial loads and critical commercial operations suffer from harmonics problems which can cost significant loss per incident based on process down-time, loss production, idle work forces and other factors. To overcome such problems, utility companies have made efforts to improve the quality and reliability of their electric power by introducing distribution static compensator (D-STATCOM). However, up to now, many research are going on D-STATCOM control scheme, suitable pulse and transformer design, dc capacitance effect and involvement with many power quality problems. This paper deals with the modelling and simulations of D-STATCOM model focus with the pulse selection, transformer design configuration and test distribution system. The issue of harmonics in the D-STATCOM is addressed by considering a 24-pulse so as to eliminate the generated harmonics. The harmonics eliminating performance of the D-STATCOM in 12-pulse, 24-pulse and 48-pulse are also investigated.
