Review on key technologies of green power supply
With the development of ship electrification, the demand for energy in ports is increasing. The location and natural resources of ports
In port integrated energy systems, different energy types have different time scales and energy transmission characteristics due to different energy transmission media. Fully considering heterogeneous energy characteristics can make the energy management model more accurate and effectively improve the system's energy utilization efficiency.
Fig. 6 shows that the implementation of solar energy in ports may lead to significant changes in abiotic factors such as temperature and humidity. In addition, the analysis revealed that wave energy had the least negative impact on average, followed by tidal energy.
In the study of traditional integrated energy systems, research on power grids, heat networks, and gas networks has been quite thorough and can be directly applied to the analysis and modeling of integrated energy systems in ports.
To meet the stochastic energy demand resulting from dynamic operational processes at ports, a simulation-based model was developed to obtain hourly energy demand and, based on the obtained energy demand, the required capacity for the PRES was planned (Li et al., 2019; Wang et al., 2019).
