Abstract Port is a focal point especially in the trade sector, where it is represented as hub for the import and export from one destination to another. Despite the fact that it gives positive impact to country specifically in economic sector but from the health sector, this activity leaves a negative impact on the environment and human health, especially those living near the port. Now, most of developed countries have made improvements by converting conventional engines (diesel engines) to electrical engines for major vehicles in ports. The same goes for shore-side ports, most of them using cold ironing (CI). However, all the modification is still raw and faced several challenges, especially in technical aspects such as voltage difference, frequency, supply / demand. It occurs due to the difference in standard voltage and frequency between shore-side and ship. Most of the ocean ship used 60 Hz. In addition, the main constraint faced is that the power supplied on the shore-side is not enough to meet the demand from customers. Thus, to make additions to the existing substation, it will require high initial costs. After evaluating the pros and cons, the new approach is taken to integrate this system into microgrid technology. Microgrid technology is a local cluster energy source with a control capability comprising Energy Distribution Resources (DER), which cover management request, storage, and loads. One of the advantages of a microgrid is that they can be connected or disconnected from the grid to operate autonomously.
