Research Of Power Distribution Control Strategy Of Multi-energy Ship Micro Network

With the increasingly serious energy problems and environmental pollution problems,the new green energy applied on the ship that becomes the important way for ship development.The Solar energy is the most potential large-scale application new green energy.With the advancement of power electronics technology and the improvement of conversion efficiency of photovoltaic cells,the solar photovoltaic power generation has a broad application prospect on the ship.However,during to the solar energy's intermittent and the small ship area,space and larger navigation area,the new energy ship using a signal solar energy is unable to meet the power requirement on the large ocean-going vessels.At the same time,in order to guarantee the reliability of the ship power supply,the ship must also increase the traditional diesel generator power supply in some small tour ships.Therefore,the Multi-energy ship power system which is composed of diesel generation,solar power and lithium battery will become one of development direction.With the change of working condition,the demand power of the ship will be changed on sailing.In order to achieve the power matching between the energy supply and the real-time operating mode,it needs to develop a reasonable energy management control strategy for adjustting the distribution of each generation unit power.The reasonable energy management strategy can solve the problem of the bottleneck of new energy,prolong the service life of equipment and improve the reliability of power supply.Hence,with the support of related topics,this article will research the power distribution control strategy of the multi-energy ship which is composed of diesel generation,solar power and lithium battery in order to improve the utilization rate.The main tasks are as follows:1.According to the solar power system and power generation characteristics of lithium iron phosphate batteries,the article will finish the topological structure designing of the multi-energy ship which is composed of solar power,lithium battery and diesel generation and come up with the power distribution control strategy.2.Researching and establishing the solar,lithium iron phosphate batteries,diesel generating sets and the power allocation strategy which has been proposed.Finally,establishing the electrical system model of the multi-power ship and corresponding simulation experiment.3.According to the simulation results,it will research energy management,control system software and set up multi-energy ship experiment platform for developing system integration technology.4.Combining to provide the prototype of the ship,it achieves the application of the new technology on the actual ship using the development of more energy system integration technology and the control strategy of the ship.
