“…Capacitor sizing and placement are critical for reactive power compensation in order to achieve an improved voltage profile and reduce power loss. Furthermore, shunt capacitor placement increased feeder availability and distribution network loading capacity [25]. Figure 3 shows a flow chart that was created using a procedural heuristic technique and applied to Figure 1 in the PSAT environment to generate the desired load flow report for the distribution network.…”

This paper presents a heuristic technique for improving the voltage profile and reducing power loss in a distribution network. These components are to be maintained at a certain standard to boost the electricity supply power of a distribution network. The shunt capacitor placement technique is applied to achieve a sustainable electric power supply. The issue of power loss has been a major threat to the distribution network. A distribution network is expected to operate at a certain voltage level to meet consumers’ energy demand. Power flow studies have been conducted using Newton Raphson’s technique on the 30 bus, 11 kV Onuiyi-Nsukka distribution network. It was found that the voltage profile on buses 19 and 26 was critically violated with voltage amplitudes of 0.72 pu and 0.79 pu respectively. The feeder power quality was improved using a shunt capacitor placement technique and the installation of a 1200KVAr shunt capacitor to keep bus voltage amplitudes within the legal limit of (0.95-1.05) pu. The voltage profile, active and reactive power losses on the network were determined. Active power loss and reactive power loss are reduced from 0.27MW to 0.12MW and 0.76Mvar to 0.14Mvar, respectively. Therefore, the distribution network voltage profile is improved and the power loss on the network significantly reduced.
