Impact of Grid Carbon Intensity on the Multi-Objective Optimization of a PV–Battery–Hydrogen Hybrid Energy System

Year: 2026
Type: conference-paper
Abstract: This paper proposes a photovoltaic, battery, and hydrogen based hybrid energy system (HES) coordinated by a fuzzy logic based energy management system (FL-EMS) and optimized using a multi-objective NSGA-II algorithm. The objectives are to minimize annualized life cycle cost (ALCC), carbon emissions, and grid energy import index (EII). The impact of grid carbon intensity is assessed by comparing a low carbon French grid and a high carbon global grid.Results show that grid carbon intensity significantly affects optimal design and operation. Under the low carbon grid, storage provides limited emission benefits, while under the high carbon grid, the system achieves up to 71% reduction in CO2emissions compared to the grid-only case. The FL-EMS adapts energy dispatch to balance cost, emissions, and autonomy.The results highlight the trade-off between embodied and operational emissions and the strong dependence of optimal HES design on grid characteristics.
