    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.

    Most of the seaports are toward green technology with a focus on renewable energy and energy storage to reduce emissions that will affect the environment and health of people living near the place. This is due to the main port's activity as a hub for connecting to other places and also trade. However, the load consumption at the seaport is high at an average of around 1,581 kW per day depending on the application. This paper presents the method to design a giant battery for energy storage to reduce diesel and grid supply used. Therefore, to purpose this the mathematical model was developed by using the generic battery of lithium-ion type based on the Shepherd model. Generic battery models are available in MATLAB/Simulink library. In particular, this study investigates how voltage and state of charge can be determined with sufficient accuracy for a given load profile. Thus, the giant battery simulation model was developed based on the mathematical model. Finally, the giant battery model is included in MATLAB/Simulink simulation, and the procedure of determining the model parameters is discussed in detail. The results show that the model can accurately represent the dynamic behavior of the battery and is assumed to operate at a maximum SOC of 80%, with a total capacity is 126500 Ah. 20% to 80% of SOC is the safe limit for the battery to operate. Besides that, the return on investment (ROI) cost also considers in this paper.
