The Impact and Placement of Photovoltaic Distributed Generation in Ship Distribution Network for Loss Reduction

Abstract

Recent advances in photovoltaic (PV) technologies, controls, and power converter topologies have resulted in the increasing application of green energy from solar in ship power system. However, there is very few research on the loss changes of shipboard distribution network produced by introduction of PV distributed generation. In this paper, we report on one ideal model and one model with an example of chain nine nodes distribution network for analyzing the impact and placement of ship distribution network with PV distributed generation. After empirical analyses, we concluded major results as follows: 1) the proper configuration of PV generation in the traditional power network can reduce the loss of distributed network effectively; 2) PV generation should be installed at the middle location of total loads; 3) the capacity of PV generation should approach the capacity of total loads; 4) PV generation should work at the lagging power factor.
