Quasi-Dynamic Time Series Analysis of Indian Practical 20-Bus Test Feeder with PV Integration

Abstract
Proliferation of Renewable Energy Sources (RES) and Distributed Energy Resources (DER) supports the development of the modern distribution network. Especially, the use of solar in distribution networks has more economic and technical benefits, such as loss reduction, improvement of system reliability, enhanced power quality, and repair of voltage profiles. However, solar photovoltaic (PV) panels are connected to the distribution feeder, the characteristics of load flow, quality of power, and voltage have changed. So, it is essential to perform the quasi-dynamic time series load flow analysis and to provide the optimal placement of PV in the distribution feeder. This paper proposes the methodology for the placement of solar by computing the Diurnal Load Factor (DLF). Moreover, it aims to meet out the day-time load demand without storage in urban feeders. Case studies on the Indian practical 20-bus test feeder to show the dynamic loads are modeled in 15 mins time interval and the effectiveness of PV utilization is validated using DIgSILENT Powerfactory simulation.
