| Abstract | Radial Distribution System is the most widely used system for power distribution because it has simple architechture and low investment costs. In contrast, due to the addition of the customers some challenges are rised about power system losses, unbalance issues and spread of harmonics which are both single phase and three phase customers. The power system losses can be overcome with the proper installation of reactive power compensator. This reactive power compensator must be installed approriately to avoid the system harmonic level exceeding the IEEE 519-1992 standard. Capacitor will be installed for compensating reactive power to maintain the voltage profile of the system. To overcome this problem, an effective algorithm is needed to identify the optimal location and capacity of capacitor in this system. This study will use harmonic power flow for distribution system. The load flow calculated voltage profile and harmonic distortion level on each bus voltage. Direct Search Algorithm works with loss sensitivity factor to find the most appropriate location and capacity of reactive power compensator without increasing harmonic distortion on the system. By considering THD, the best and location and capacity of reactive power compensator will be yielded while maintaining the voltage profile and minimize the power system losses. |
