舰船电力系统中智能电网技术的应用浅析

  目的  由于海面传感器的耗能点分散、负荷波动幅度较大且节能降耗的需求迫切，为了优化能量供给模式，提出面向海面传感器的船载能量网络（SEN）。  方法  首先，基于车载能量网络、动态无线充电技术及电动船舶技术，分析SEN模型的可行性；然后，基于海面传感器的特点，建立SEN模型，提出能量传输最大化和能量损失最小化这2个问题，并定义问题模型和约束函数；最后，通过开源模型MaritimeSim选取基础实验数据集。  结果  实验结果表明，通过合理设置参数，SEN能够将海上可再生能量传输至海面传感器节点，从而补充电力网络并增强其电能传输能力。  结论  研究成果可为优化海面传感器的能量供给提供新的设计方法。

Application of smart grid technology to shipboard power system

  Objectives  In terms of ocean sensors, their energy consumption points are scattered and the load fluctuation is drastic, with urgent need in energy conservation and consumption reduction. In order to optimize the energy supply of the ocean sensors, this paper studies the Ship-borne Energy Network(SEN) for ocean sensors.  Methods  Firstly, the feasibility of SEN model is analyzed based on the development of vehicle energy network, dynamic wireless charging technology and electric ship technology. Next, based on the characteristics of the ocean sensor, the SEN model is established to propose two issues of energy transmission maximization and energy loss minimization and define problem model and constraint function. Finally, we select the basic experimental data set through the open source model MaritimeSim.  Results  The experimental results show that SEN can transfer offshore renewable energy to ocean sensors node under some reasonable settings, complement the power network and enhance its power transmission capability.  Conclusions  The study results can provide new design method for optimizing the energy supply of ocean sensors.
