Energy consumption estimation and management of the maritime Unmanned Surface Vehicles (USV) is an important issue to deal with energy minimization techniques such as path planning, tasks scheduling, etc. In this paper, we introduce the energy consumption parameter in USV simulation through three contributions: 1) An analytic USV's energy consumption model is developed based on the three-degrees-of-freedom dynamic model of surface vessels. 2) A reverse engineering approach is proposed to identify the previously used dynamic model parameters based on a set of scenarios executed within a recent simulation environment. 3) The simulator engine is enriched with the consumption modelling tools such that the power absorbed by the USV is instantaneously calculated and returned; thus, the required energy of any predefined scenario is available as a new simulation result.

海上无人水面飞行器（USV）的能耗估算和管理是处理诸如路径规划，任务调度等能耗最小化技术的重要问题。在本文中，我们通过三个贡献介绍了USV仿真中的能耗参数：1）基于水面舰船的三自由度动力学模型，开发了一种分析型USV能耗模型。2）提出了一种逆向工程方法，以基于在最近的仿真环境中执行的一组场景来识别先前使用的动态模型参数。3）仿真器引擎具有丰富的功耗建模工具，可以即时计算并返回USV吸收的功率；从而，
