摘要
为了提升包含柴油发电机、光伏阵列及储能装置构成的小型混合动力船舶微网系统在复杂航行状态下的运行稳定性,首先对各电能变换装置建模,并在此基础上提出了一种适配于工况负荷动态波动下船舶微网的能量管理调度策略,分析了逆变电源在不同工况下的转换控制方法。然后在此基础上利用MATLAB/SIMULINK建立准确描述系统的仿真模型,并进行能量管理策略仿真。仿真结果表明,该能量管理调度策略能够有效地控制船舶微网各单元的功率输出,满足船舶在不同运行工况下对功率分配的需求,实现微网稳定运行。
A small hybrid ship micro-grid system consisting of a diesel generator,a photovoltaic array and a storage device was built,the improvement of the operation stability for the ship micro-grid power system was studied under the complicated navigation condition. Firstly,based on the modeling of power converters,an energy management dispatch strategy was proposed which was suitable for dynamic loads fluctuation for ship micro-grid. Then,the switching control method of inverter power supply under different working conditions was analyzed. At last,MATLAB/SIMULINK was used to establish the simulation model of the micro-grid system,and the simulation research on energy management strategy was carried out. The simulation results showed that the proposed energy management strategy can effectively control the power output of each power unit of the ship＇s micro-grid. It can meet the demand of power distribution in different operating conditions and realize the stable operation of micro-grid.
