Allocation of Renewable DG Considering Impact of ZIP Load Models in Distribution Network

In future green energy will be the global energy market due to its abundance and sustainable nature. Based on this, the modern PV system and wind turbine DGs are being installed in the distribution system to meet the increasing load demand. In this work, the IEEE 33 bus system is considered, with 7 PV systems and 2 wind turbines being installed at different bus locations. The two system studies are considered, which are the constant power load model and the polynomial ZIP load model. For both cases, the voltage profile is plotted and compared for different cases. Three different times are taken to understand the performance of PV-based DGs. It was found that installing this system has drastically improved the voltage profile on all buses. It can be seen that both active and reactive power losses are also reduced when PV and wind systems are taken into consideration which ultimately improves the efficacy and reliability of the system.
