为减少舰船航行过程中的污染物排放量，降低航行成本，研究绿色能源背景下的舰船动力系统能耗优化方法。绿色能源背景下，以最小总能耗、最小二氧化碳排放量、最小航行成本为目标函数，以绿色能源转换效率及灵活性转换效率等为约束条件，建立舰船动力系统能耗优化模型，减少舰船航行过程中的污染物排放量，降低航行成本；通过求解该模型，获取最小总能耗、最小二氧化碳排放量，以及最小航行成本对应的能耗优化方案，实现能耗优化。实验证明该方法可有效优化舰船动力系统能耗；在不同水流速度与对水航速时，应用该方法均可降低舰船航行的总能耗、二氧化碳排放量与航行成本。
In order to reduce the pollutant discharge and sailing cost, the energy consumption optimization method of ship power system under the background of green energy is studied. Under the background of green energy, with minimum total energy consumption, minimum carbon dioxide emission and minimum navigation cost as objective functions and green energy conversion efficiency and flexibility conversion efficiency as constraint conditions, an optimization model of ship power system energy consumption was established to reduce pollutant emission and navigation cost during ship navigation. By solving the model, the energy consumption optimization scheme corresponding to the minimum total energy consumption, minimum carbon dioxide emission and minimum navigation cost is obtained, and the energy consumption optimization is realized. Experimental results show that this method can effectively optimize the energy consumption of ship power system. This method can reduce the total energy consumption, carbon dioxide emission and sailing cost of ships at different flow speed and speed against water.
