Renewable energy integration, particularly the inclusion of intermittent sources such as solar and wind power, has become a cornerstone in the global transition towards sustainable and low-carbon energy systems. Distribution transformers play a pivotal role in this integration process, as they are key components in connecting distributed renewable energy resources to the electrical grid. Here, we delve into below challenges related to distribution transformers in facilitating this integration.

1. Fluctuating Loads: Solar and wind power generation is inherently variable due to weather conditions and time of day, leading to fluctuating loads on the grid. This variability can stress distribution transformers designed for more consistent load profiles.

2. Reverse Power Flow: Unlike traditional power systems where electricity flows from the grid to consumers, renewable energy systems can feed power back into the grid, causing reverse power flow. This can lead to operational and protection issues for transformers not designed to handle bidirectional power flow.

3. Voltage Regulation: Intermittent renewable energy sources can cause voltage fluctuations at the point of connection, impacting power quality and potentially damaging transformers and other grid equipment.

4. Capacity Utilization: As renewable energy penetration increases, distribution transformers may need to be oversized to accommodate peak generation periods, leading to underutilization during off-peak times.
