Abstract
The energy enhancement of ports and their sustainable development is an area that requires immediate attention on a global scale. In most cases, the equipment which they operate is obsolete, thus leading to increased consumption and uncontrolled emissions of any kind. That is why a directional strategy is needed to reduce the environmental impact as much as possible, taking into consideration the economic sector and social acceptance.
In the present dissertation, the project of modernization of the port of Heraklion was examined, based on outdated technology and the conventional methods of energy production offered by the island, in an innovative, independent by the central electricity network of the city with zero ecological footprint. After studying and evaluating the various energy-intensive sectors, as well as the energy production and management systems of the island, a total of 8 modeled scenarios were analyzed in depth with the appropriate software. For each of these scenarios, renewable energy sources (photovoltaic panels and wind turbines), energy storage systems (batteries) and the method of Virtual Net Metering) were dimensioned, taking into account the climatic conditions of the area. The parameters that characterize them are the 24 and 48 hour autonomy offered, the sale of the excess, not stored energy in the central network of the city for the two aforementioned categories as well as the energy state of its lighting before and after its upgrade.
Through the analysis and comparison of the results, it was concluded that the current system is not optimal, is not in line with the technological progress of the time and needs immediate replacement. Then, a scenario was chosen which is considered the most balanced and able to meet all the requirements of the port as much as possible. Specifically, the selected optimal scenario achieves almost complete independence from the main electricity network of the city, while reducing the consumption of outdoor lighting by almost 56%.
