Design A Giant Battery Energy Storage for Port Application

Abstract

Abstract 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.
