Abstract
To accelerate the decarbonization of the coastal fishing and aquaculture industry, electric as well as hydrogen-electric propulsion vessels are being designed to be deployed in the coastal areas of Norway. The purpose of this paper is to examine the impact of inclusion of fishing vessels charging infrastructures and hydrogen electrolysers on the Lofoten regional network. The real network has been implemented in DIgSILENT Power Factory and quasi-dynamic simulation has been conducted. Real load data and energy requirements for fishing vessels in harbours have been used to simulate different operational scenarios of the network. Hydrogen electrolysers to cater the real energy need of hydrogen-electric fishing vessels in the coastal region have also been implemented. The maximum load for the existing system and the predicted increase by year 2030 and 2050 have been considered for the analysis. The lines loadings and buses voltages of the regional grid are examined with charging infrastructures and hydrogen electrolysers, and solutions to mitigate the violations are proposed. An energy management strategy has also been applied to investigate the impact and possibility of integration of hydrogen electrolysers in the regional grid.
