Modelling, Control And Simulation Of DC Micro-Grid For Meritime Applications

Abstract

Nowadays, modern Reefer ships are using renewable energy sources for e.g. (PV, Wind, Fuel Cell, etc.,) to meet their energy demand along with fossil fuel(s). The concept of an electric powered ship is not something new. Power electronic converters are required for the integration of renewable sources and loads within the micro-grid. One of the key differences between the terrestrial micro-grid and the maritime one is that it is an islanded micro-grid. World is facing energy crises badly, especially in Pakistan. Pakistan has a lot of renewable energy sources available. To increase the efficiency multi energy system is recognized, because most of the loses are based on conversion like heat energy to electrical energy conversion and electrical energy to heat energy. The conventional method of electricity generation is very expensive and also not effective this system depends on many factors. Now there is a big advancement in renewable energy sources which are very cost effective. Renewable sources provide clean energy where is no pollution and also these sources are free. Solar based energy generation system is very famous in Pakistan and is of very cost effective. Wind power generation system introduced and working fine for power generation. Multi sources integration with grid is the main factor in which we can reduce the losses and also provide extra energy to WAPDA. Inverter plays vital role in renewable energy resources, because lower the losses efficient the complete system. Grid connection gives more advantages to renewable energy systems because sometimes renewable energy sources are not available or less power available from these sides so we shift ourself or share the resources with grid.
