Energy-Saving Technology for Increasing Efficiency of Energy Production

Abstract

When battery storage system incorporate into modern power system began a critical answer to problems such as voltage instability, energy imbalances, and the increasing use of renewable energy. This thesis investigates the impact of incorporating a lithium-ion batteries into Absheron 500/330/220 kV substation and compares its performance with and without batteries. To establish the system's total efficiency, the study conducts thorough simulations and evaluations of changes in voltage stability, load flows, and energy losses. The analysis begins by providing a complete overview of how the Absheron substation operates, emphasizing the importance of its 500 kV, 330 kV, and 220 kV buses in the regional power system. The thesis uses a combination of theoretical models and simulation tools to predict load flows and voltage profiles for two scenarios: one in which the battery is not incorporated and one in which the system is supported. The battery-integrated scenario contains parameters such as 6,000 full charge-discharge cycles at 100% efficiency and an additional 1,500 cycles at 80% efficiency, reflecting the battery's real-world performance. The results demonstrate that integrating the battery improves voltage stability significantly across all busbars. For example, the voltage on the 500 kV busbar rises from 484.8 kV to 485.7 kV, resulting in improved dependability and operational stability. Similarly, load balancing on important transmission lines improves, lowering voltage on overcrowded lines while enhancing power distribution. The battery also decreases energy losses, which provides long-term economic benefits. The cost-benefit analysis reveals that, while the initial investment for the battery system is over US$35 million, the annual energy savings and reduced fuel use at the Solar Power Plant give a 5-year payback period. Furthermore, the report cites limitations such as lithium-ion batteries' short lifespan and high initial cost, while emphasizing their potential to improve grid resilience and incorporate renewable energy sources. Recommendations include optimizing charge-discharge cycles to increase battery life and using renewable sources like wind or solar to lessen rely on natural fuels. This thesis finds that incorporating BESS into high-voltage substations is a feasible and successful technique for improving grid performance. The findings are useful for politicians, utility operators, and engineers looking to increase efficiency and stability in modern power systems as they transition to sustainable energy sources.
