Abstract-Distributed Solar Photovoltaic (DPV) plants connected along distribution feeders change the original daily load curves of these feeders into daily net-load curves that return lower peak load values. Doing medium voltage (MV) network design and development based on net-peaks may affect the reliability of distribution feeders with DPV connections. On the other hand, estimating original peaks by arithmetical summation of net-peak and total DPV ratings returns over-estimated peaks. This reduces the efficiency of network assets utilization and, consequently, overestimates network expansion requirements. A distribution planning tool (DPT) has been developed to generate the original daily load curves of distribution feeders without DPV impact, from which original peaks can be obtained and used in planning procedures. The DPT is developed to operate with actual weather data and DPV design specifications. It has been applied on existing case study of 11kV feeder considering different scenarios.
