Design of an intelligent sensing and communication network for microgrid

Abstract

This project is to design and set up a Land-based Energy Management System

(LEMS) that is capable of incorporating renewable and traditional energy

resources.The proposed system of 50/60 Hz three-phase variable voltage in the range

of 400 V will be used for powering ships at berth. The system provides an

application that is capable of metering and charging the kWh amount of shore-toship

energy. An electric bill is automatically generated at the end of the grid

connection. The system is scalable and capable of simultaneous energy transfer to

two or more vessels when the system supply capacity is expanded in the future.

LEMS helps to switch from the ship's heavy fuel oil (HFO) to cleaner land-based

fuels (primarily gas) and hence cuts down unnecessary CO2 emissions. It opens up

new business opportunities by providing electric energy to ships.

The objective of the Final Year Project is to focus on metering and billing modules

which includedesign and implement an electronic billing system and energy

purchased data logging for shore power application. Power meters are set up for realtime

monitoring of the power sources and loads by acquiring data from the meter to

transmit through graphical user interface by using LabVIEW programming. The

reliable and efficient electronic billing system will then calculate the exact amount of

energy usage and generate bills. Testing will be carried out through designing an

Energy Management System (EMS) for real-time monitoring and system

functionalities.
