DESIGN ANDDEVELOPMENTOFHYBRID MICROGRIDFORASHIP

Abstract

In this thesis the technology of hybrid microgrid in which PV solar cells in conjunction with energy storage devices seek to reduce dependence on conventional diesel generators to meet the shipboard electrical load requirements. 230V loads which include general lighting, navigation and communication equipment, public address system which constitute a considerable share of online electrical load in any shipping vessel is the primary focus. DC power from solar cell is converted to AC power using suitable converters or drives for the same. The entire shipboard power system is modelled using Matlab Graphical User Interface Development Environment. A Power Management System to carry out optimal power generation and scheduling is designed which include diesel generator fuel cost optimisation is implemented to control the hybrid microgrid here used.
