Assessment Method for the Construction Effect of Port Hybrid Renewable Energy Systems from a Near-Zero Carbon Perspective
Under the current requirements of near-zero carbon emission goals,ports,as crucial sea-land hubs,must actively assume responsibility for green and low-carbon development.By fully utilizing renewable energy sources,such as wind and solar power,and rationally allocating the scale of renewable energy systems,ports can maximize their energy self-sufficiency.Balancing economic feasibility and environmental sustainability to reasonably config-ure the scale of integrated renewable energy systems is crucial for the current stage of port development.To address this challenge,this paper employs HOMER Pro as the simulation tool for constructing a near-zero carbon hybrid re-newable energy system for ports,including real-time assessments of power supply and consumption.An evaluation model is established using the entropy-weighted TOPSIS method,analyzing and comparing construction scenarios of hybrid renewable energy systems based on economic and environmental indicators.Taking J port,a typical port along the Yangtze River in Jiangsu province,as an example,this study uses field survey data on resource endow-ments such as wind speed,daily radiation flux,and ambient temperature to conduct simulation analysis via HOMER Pro.The study compares three distinct scenarios:a standalone photovoltaic system,a standalone wind turbine sys-tem,and a wind-solar hybrid system,to validate the feasibility of the model.The results indicate the following opti-mal configurations for J Port under a surplus electricity grid connection mode:7.8 MW photovoltaic panels,five 3 MW wind turbines,and a hybrid configuration of 6.2 MW photovoltaic panels with fifteen 3 MW wind turbines.Re-sults show that the photovoltaic system demonstrates limited emission reduction potential,replacing only 19％of the port's energy consumption and exhibiting a high dependence on the national power grid.In contrast,the stand-alone wind turbine system satisfies 40％of the port's energy demand,outperforming the photovoltaics in both eco-nomic and environmental aspects.The wind-solar hybrid system further enhances the environmental performance of the grid-connected system,supporting 70％of the port's energy demand and achieving a 65％reduction in carbon emissions.
