“…Nonetheless, the advantages of the V2G implementation are substantial, and the marina could techno-economically benefit in the future from the application of boat flexibility and EV bidirectional charging, enabling the integration of more renewable energy without additional grid reinvestment. The obtained results clearly show the improvements in the operation of Ballen marina's energy system, compared to the previous research in this area [28][29][30]45].…”

“…In the future scenario, the impact of V2G technology implementation on the batteries' degradation was studied based on the employed battery ageing model. The optimisation model comprising the marina's generation, storage, electric cars, and boat flexibility was established, expanding the scope of previous research on marina energy systems [28][29][30]. The developed optimisation algorithm for the marina's energy management system-coordinating all the above-mentioned elements along with the battery degradation model-constitutes the novelty of this work.…”

The emerging concept of integrated community energy systems (ICESs) proves its suitability for improving the operation of local grids—increasing self-consumption from local generation, enhancing the load factor, and reducing energy cost. In Ballen marina—located on the Danish island of Samsø—the battery energy storage system (BESS)’s action can be possibly complemented by the flexibility of boats and electric cars. With the greater involvement of energy consumers, the energy system’s performance may become more efficient—from both technical and economic perspectives. Within this framework, the optimal charging and discharging strategies of the marina’s electric cars were developed and evaluated. The car usage profile was generated, utilising a stochastic approach to resemble daily variations in the driving pattern. The optimal charging strategy was established, subsequently integrating this action with boat flexibility. As a future scenario, the benefits of vehicle-to-grid (V2G) technology implementation were examined, proving significant enhancements of the future marina’s grid—with increased photovoltaic (PV) generation capacity and the number of electric cars. The economic benefits of bidirectional charging were proven, with ample advantages for the marina and the rental company, leading to cost savings of up to 51.7% and minimising the energy export by 21.3%. Therefore, increasing the integration level of Ballen marina’s flexible units—electric cars and boats—was concluded to be an important goal for the coming years.

“…Nevertheless, the majority of vessel-flexibility studies focus on optimal scheduling of generation and voyage, not considering the interactions between vessels and onshore electrical grid [23][24][25][26]. The boat demand flexibility can become an essential element of smart marina energy systems, complementing the integrated operation of renewable generation and BESSs [3,27,28].…”

Implementation of alternative energy supply solutions requires the broad involvement of local communities. Hence, smart energy solutions are primarily investigated on a local scale, resulting in integrated community energy systems (ICESs). Within this framework, the distributed generation can be optimally utilised, matching it with the local load via storage and demand response techniques. In this study, the boat demand flexibility in the Ballen marina on Samsø—a medium-sized Danish island—is analysed for improving the local grid operation. For this purpose, suitable electricity tariffs for the marina and sailors are developed based on the conducted demand analysis. The optimal scheduling of boats and battery energy storage system (BESS) is proposed, utilising mixed-integer linear programming. The marina’s grid-flexible operation is studied for three representative weeks—peak tourist season, late summer, and late autumn period—with the combinations of high/low load and photovoltaic (PV) generation. Several benefits of boat demand response have been identified, including cost savings for both the marina and sailors, along with a substantial increase in load factor. Furthermore, the proposed algorithm increases battery utilisation during summer, improving the marina’s cost efficiency. The cooperation of boat flexibility and BESS leads to improved grid operation of the marina, with profits for both involved parties. In the future, the marina’s demand flexibility could become an essential element of the local energy system, considering the possible increase in renewable generation capacity—in the form of PV units, wind turbines or wave energy.

“…One of the main solutions is the large-scale urban generation of renewable energy [6]. Solar, biomass and wind are the most commonly available RESs that can be used in cities to promote self-consumption [7]. In these cases, a strategy that facilitates the selfsufficiency is the integration of battery storage systems in connection with RES technologies which supply energy in a discontinuous way according to climatic conditions [8].…”

In Europe, 70% of citizens live in urban areas and consume around 75% of the primary energy supply. In order to reduce the impact of energy consumption and improve the competitiveness of local energy systems, Energy Communities may help to address the challenges of urban sustainability and energy security through local energy production and self-consumption. Solar, biomass and wind are the main sources of renewable energy that are generally used in cities. However, not all the sources available in urban environment are usable, due to the limited availability, or other technical or non-technical limits and constraints. In order to promote renewable energy technologies in buildings it is necessary to consider architectural, cultural, energy, technical and economic feasibility. This work defines a methodology for the optimal design of grid connected PV-battery systems in urban environments. The model was applied to two districts located in the city of Turin with the aim of evaluating the technical feasibility of combining multiple residential users at city level. The purpose of this work is to promote self-consumption and self-sufficiency from the network, using the integration of solar energy with PV-battery systems, and to reduce electrical losses in favor of both the single user and the distribution system. Results show that different values of self-sufficiency and self-consumption can be reached depending on the shape and dimension of each building. It was shown that it is possible to satisfy the current requirements to become an Energy Community in an urban environment with good levels of self-sufficiency.
