Abstract
This article presents the modeling and assessment of the energy efficiency of a hybrid energy system of a marine vessel, which combines traditional energy sources (diesel generators) with renewable energy sources such as solar panels and wind turbines. Based on mathematical models and simulations in the MATLAB/Simulink environment, the dynamics of energy consumption, battery charge/discharge modes, renewable energy generation and its impact on specific CO emissions are analyzed. Analytical expressions for determining the integral fuel equivalent, load factor and total efficiency are proposed, which allow for scenario analysis and feasibility studies of hybrid systems. The simulation results confirm that hybridization allows for a fuel consumption reduction of up to 25%, as well as a reduction in CO emissions, especially in peak solar power generation conditions. The described approach provides a platform for further optimization of ship power system configurations, taking into account real ship operation profiles and climatic conditions.
