Modeling And Simulation Of Ship Power System Integration Of Solar Energy

With the world's growing demand for energy and environmental awareness of the gradual strengthening of the shortage of traditional fossil fuels and serious pollution of the ecological environment,the development and utilization of new energy sources has become an inevitable trend of future development.Solar energy as a clean,non-polluting,extensive new energy sources more and more attention around the world.Application of new energy in the ship is no longer a new subject,the United States,Switzerland,Australia,Germany and other countries have achieved some results.As the marine environment is worse than the terrestrial environment,sunlight intensity and PV module temperature changes and other issues on the output of PV systems have a negligible impact.Harsh sea will increase the incidence of failure to consider the impact of frequent changes in the ship power system.Therefore,the need to build a simulation model,simulate the effect of a variety of conditions to facilitate the ship power system,to find ways to avoid or resolve.This paper established a ship into the solar power system simulation model to study the effects of changes in the normal navigation conditions on the sun light intensity ship power system.The main impact of the article added solar power system of the ship power system,therefore,will be integrated into solar power system is divided into a typical ship ship power systems and solar photovoltaic power generation system of two parts.First,through the ship power systems research and analysis,according to the modular idea for prime mover and its control system,generator and excitation system,induction motors and other modules to classify modeling;secondly,the PV system modeling study of the solar cell module,the maximum power point tracking module,the boost chopper circuit and grid inverter circuits and other components.To take advantage of PSCAD / EMTDC simulation software to build a ship into the solar power system model to simulate the effect of light intensity on the ship into the solar power system.Finally,in order to stabilize the PV system instability brought the volatility,the basic principles of marine research and flywheel energy storage model,but also the use of genetic algorithms for the energy storage capacity of a simple optimization.In this paper,the method used to establish the model are a mature technology approach on the part of the modeling process simplified model is appropriate,but it does not produce a large deviation of actual results.Simulation results verify the feasibility and effectiveness of modeling.Therefore,the work done by this paper has certain reference value to study solar energy applications in the ship.
