Influence of Photovoltaic Wheeling Systems on Low Voltage Distribution Feeders in Electrical power system

Renewable energy generation (REG) is a crucial topic for researchers, policymakers, and governments to address global warming issues. Nowadays, distributed photovoltaic (DPV) systems are used to reduce losses in low-voltage distribution utilities and stabilize the voltage across all buses. An important aspect of this research is the allocation of these panels. In order to achieve optimal results, this paper simulates and analyzes algorithms to identify the best locations in low-voltage feeders and the impact of this penetration on harmonics, reactive power, and voltage profiles. In some cases, such as with long feeders or heavy loads like arc furnaces and large motors, simple allocation may not work ideally. Therefore, it is necessary to use static var compensators (SVC) or distributed or centralized capacitor banks. However, due to the cost of capacitor banks, it is advisable to use an automatic voltage regulator (AVR) to reduce losses and maintain voltage stability. In certain situations, conservation voltage reduction (CVR) can decrease power flows in distribution lines, freeing up capacity. Finally, the system is modeled and studied using CYME software with the Isfahan database.
