      1.5.2 Optimum Placement of RDGs and Shunt Capacitors to 69-Bus Distribution Network

As mentioned earlier, using mixed discrete SPBO the sizes and locations of biomass DG, solar PV, and shunt capacitors have been optimized. The size of solar PV and the locations of the RDGs and shunt capacitors have been optimized considering 15^th load hour of the day. The optimum locations of biomass DG, solar PV, and shunt capacitors are found to be bus numbers 61, 21, and 17, respectively. Table 1.7 presents the optimum sizes and locations of biomass DG, solar PV, and shunt capacitors obtained using the mixed discrete SPBO algorithm, with an objective to minimize the J for different load hours. Figure 1.6 presents the graphical representation of a comparative study of active power loss before and after placement of RDGs and shunt capacitors to 69-bus distribution networks. From Table 1.7 and Figure 1.6, it may be clearly noticed that, after the placement of RDGs and shunt capacitors to the distribution network, the active power loss reduces significantly for all the load hours of the day considered in this study. At the 15^th load hour, the active power loss reduces from 224.96 kW to 11.2002 kW. Even in the absence of solar power injection, the active power loss reduction after the placement of RDGs and shunt capacitors is found to be quite significant for different load hours. Figure СКАЧАТЬ
