基于混合储能的船舶微电网直流母线电压稳定控制

A Control Strategy for DC Bus Voltage of Marine Microgrid Based on Hybrid Energy Storage

环境污染问题是当今的大问题,生态环境的可持续发展也是现在的热点,因此船舶微电网中利用新能源与清洁能源发电也逐渐被提上日程。直流微电网中大量分散的可再生能源发电单元具有随机性和波动性,会对船舶微电网中直流母线电压造成严重干扰。若不采取适合的方法会引发严重的后果。而随着储能技术的不断发展,超级电容等新型储能单元与传统的锂电池和蓄电池技术一起,能较好地解决这个问题。因此本文研究了一种基于储能的船舶微电网直流母线电压稳定控制方法,提出适用于船舶直流微电网的锂电池与超级电容器的混合储能结构,以达到对船舶直流微电网直流母线电压的稳定控制。

Environmental pollution is a big problem today, and the sustainable development of the ecological environment is also a hot spot. Therefore, the use of new energy and clean energy in the ship’s microgrid is gradually being put on the agenda. The large number of decentralized renewable energy power generation units in the DC microgrid have randomness and volatility, which will cause serious interference to the DC bus voltage in the ship’s microgrid. Failure to take the appropriate approach can have serious consequences. With the continuous development of energy storage technology, new energy storage units such as super capacitors can solve this problem better together with traditional lithium battery and battery technology. Therefore, this paper studies a DC-bus voltage stability control method for ship microgrid based on energy storage, and proposes a hybrid energy storage structure for lithium battery and supercapacitor for marine DC microgrid to achieve DC bus voltage of marine DC microgrid. Stable control.
