Description

Technical Field

[0001] This application relates to the field of ship energy management, and in particular to a multi-objective zero-carbon ship energy management method, system, equipment, medium and product. Background Technology

[0002] Fuel cells, as clean and efficient power generation devices, boast advantages such as high energy conversion efficiency, low noise operation, and near-zero pollution emissions. Their main byproduct is water, thus, when applied to navigation propulsion systems, they can effectively reduce emissions of greenhouse gases and air pollutants such as carbon dioxide and nitrogen oxides, significantly contributing to improving the atmospheric environment of ports and shipping routes. Meanwhile, lithium batteries, with their high energy conversion efficiency, excellent instantaneous power response, and long cycle life, can achieve pollution-free operation under electric drive, providing stable and clean energy support for shipping systems. Using fuel cells and lithium batteries as the core energy source for ship propulsion can not only effectively reduce dependence on traditional fossil fuels and minimize environmental damage during ship operation, but also play a crucial role in addressing global energy shortages and promoting the green and low-carbon transformation of the shipping industry. However, in the complex and ever-changing real-world scenarios of ship operation, ensuring the stable lifespan of fuel cells and lithium batteries and reducing their total life-cycle costs remain key challenges that need to be addressed.

[0003] Superconducting energy storage systems (SMES), as a novel marine propulsion energy source, possess unique advantages such as near 100% charge / discharge efficiency, extremely high power density, and millisecond-level rapid response. They can provide or absorb high-power electrical energy under transient conditions, ensuring the stability and safety of the ship's electrical system. Unlike fuel cells, which primarily provide continuous power, and lithium batteries, which mainly provide medium- to long-term energy support, superconducting energy storage is better suited for handling short-term impact loads and rapid dynamic adjustments, demonstrating an irreplaceable role in high-power fluctuations, start-up and shutdown conditions, and power quality management. Therefore, applying superconducting energy storage in conjunction with fuel cells and lithium batteries in marine propulsion systems can not only improve the system's flexibility and robustness and effectively extend the lifespan of fuel cells and lithium batteries, but also achieve the goal of multi-energy complementarity and optimized operation in green shipping.

[0004] Based on the respective advantages of fuel cells, lithium batteries, and superconducting energy storage, the synergy of the three as a marine power system can achieve efficient complementarity: fuel cells provide continuous and clean basic power, lithium batteries are responsible for medium- and long-term energy support and smooth load fluctuations, while superconducting energy storage can quickly adjust power under transient conditions, alleviate sudden loads and start-stop shocks, thereby significantly improving the system's dynamic response capability, energy utilization efficiency, and overall reliability, forming a stable, efficient, and green multi-source power supply system.

[0005] Based on the characteristics of the aforementioned multi-source propulsion systems for ships, refined energy management of each energy unit is necessary to ensure the safety and economy of ship operation. Since fuel cells, lithium batteries, and superconducting energy storage differ in power response speed, energy capacity, and lifespan, the system must rationally allocate the output of each energy source to meet both the ship's instantaneous and continuous load demands while avoiding overload or deep cycling of a single energy source, thereby extending the overall system lifespan. Among these, fuel cells and batteries, as core energy sources, are significantly affected by power fluctuations, frequent load changes, and high-rate operation. Therefore, energy management strategies must not only focus on energy balance and efficiency optimization but also prioritize controlling the output power fluctuations of fuel cells and batteries to slow down their degradation rate and achieve safe, efficient, and sustainable multi-source propulsion operation for ships.

[0006] Existing collaborative solutions suffer from inaccurate fuel cell lifespan modeling, lack of consideration for multi-objective optimization, and inadequate optimization strategies, resulting in suboptimal results. Furthermore, these issues arise due to the simplistic modeling and basic optimization methods used, leading to poor multi-objective collaborative optimization and energy waste.

Based on the objective function of the multi-source ship propulsion system model, it determines a multi-objective model predictive control (MPC) energy management strategy for energy management, achieving multi-objective collaborative optimization.
