Optimization of Battery Energy Storage System in Active Distribution Networks

Abstract

Battery Energy Storage Systems (BESS) are potential options for mitigating the effect of new loads and renewable energy storage systems. It’s critical to have a strong battery thermal management system (BTMS) in place to keep the battery packs’ characteristics and lifespan intact. The status of a battery is also an essential aspect to consider when it comes to performance. As a consequence, in this study, a fuzzy logic controller is utilized to enhance thermal management and the state of charge of a battery system. The usage of a hybrid cooling system that includes a phase change material (PCM) and a liquid cooling system, as well as Nano silver graphene particles, was first used to achieve thermal control. The coolant system is stimulated based on the controller’s optimal temperature setting, allowing for efficient heat dissipation. Then implementing a feedback-controlled charging system that utilizes sequenced charging of the weak capacity battery in the pack to ensure maximum State of Charge (SOC) in the system improves the battery’s SOC. Thereby the performance of the system showed enhanced results by maintaining the system at an optimum working temperature range not exceeding 40 °C. The system also achieved a battery voltage of 25.7 V and a battery current value of 5A after loading. The discharging voltage of the system is predicted to be 50.0275 V and the energy of the battery is found as 100 J after loading. As a result, the thermal management and the state of charge of the battery were improved by the incorporation of the fuzzy logic controller in the system.
