The growth and development of Electric Vehicles in Indonesia are targeted to grow rapidly based on presidential regulation No. 22/2017 - National Energy Plan and No. 55/2019 - Acceleration Program of Battery-Based Electric Vehicles for Road Transportation. By the Electric Vehicle penetration, there will be additional new loads on the customer service transformer side. This thesis will discuss the impact of Electric Vehicle penetration on the peak load on the 100 KVA Residential Area Transformer and also proposes three strategies for charging the Electric Vehicle battery to reduce the peak load on these transformers. The Residential Area Transformer will be penetrated by the Electric Vehicle load in stages of 5, 10, 15, 20, 25, 30 EVs and observe the impact of the penetration on the peak load of the transformer. There was a quite high increase in the penetration of EVs of 15, 20, 25, and 30 EVs. With the penetration of 30 EV, it will increase the peak load on the transformer to 123.6 KVA. This means that the 30 EV penetration load exceeds the 100 KVA Transformer Residential capacity limit. Of the three EV charging strategies offered, with sequences per group of 4, 3, and 2 EV, it was found that the best charging strategy to reduce the peak load of the transformer by shifting the peak load to the valley is charging strategy 2 with sequencing per group of 2 EV. By implementing the charging strategy 2 with sequencing per 2 EV groups, the peak EV load on uncontrolled charging was 123.6 KVA, becoming 66.03 KVA, and there is a decrease in peak load by 46,59 percent.
