“…The integration of artificial intelligence emphasizes the potential of reliable models supporting the progress of oceanic renewable energy systems. The analysis presented in [82] explores synergy between renewable generators, lithium-ion batteries, and hydrogen-based powerto-power solutions in smart grids. Emphasizing the crucial role of hydrogen in achieving higher renewable fractions and its capacity for seasonal storage, the study suggests that hydrogen storage becomes fundamental beyond a 40% renewable penetration, maintaining system stability.…”

“…On the generation side, a possible strategy could be the adoption of polygeneration systems to achieve a more flexible production of renewables, as proposed by Bartolini et al and Simões et al [8,9]. Moreover, the increase of the selfconsumption rate through integration with different systems, such as hydrogen production, as shown by for Pastore et al [10] and other studies [11,12] represents a viable solution.…”

The target of a Renewable Energy Community (REC) is to improve the renewable energy consumption without forcing the grid to work as a power backup and avoid the installation of large energy storage systems. The paper proposes a comparison between different REC configurations with the same annual energy consumption of 500 MWh corresponding to about 200 residential houses in northern Italy. The comparison includes different kinds of building destination (residential, commercial, industrial), and different photovoltaic (PV) installed capacity. The results highlight the fundamental role of a proper design of the Renewable Energy Community configuration. RECs based on members with complementary loads enhance the renewable energy consumption by increasing the fraction of shared energy. Different roles (consumer and prosumer) are fundamental to provide the proper energy distribution during the sunny hours by producing a win-win condition. Nevertheless, an increase of the PV capacity can produce a detrimental effect on the shared energy ratio due the non-contemporaneity of production and consumption.

“…In the system, the power grid is at the "Core level", and the energy obtained by EV from the grid is at the "Carrier level" [19]. Most of the existing research results are based on optimizing renewable energy sources [20][21][22], such as photovoltaic and wind power generation [23], to reduce the peak load of the grid or through the rational placement of fixed charging facilities for energy storage [24,25]. Habib et al [26] proposed a method to simulate the operation effect of photovoltaic power generation as a static synchronous compensator to alleviate the peak load of the power grid.…”

Many electric vehicles connected to the grid will lead to problems such as poor stability of power grid generation. The key to solving these problems is to propose an efficient, stable, and economical valley-filling charging scheme for electric vehicles and grid users in the vehicle network system. Firstly, the convex optimization theory is used to make the grid achieve the optimization effect of valley filling. On this basis, the electricity price scheme with a time-varying coefficient as the variable is proposed to meet the single objective optimization of EV charging cost optimization, and its degree of influence on the grid valley-filling effect is analyzed. Secondly, based on the competitive relationship between EV charging cost and battery life, the P2D model is simplified and analyzed, and the attenuation law of battery capacity is quantitatively described. The multi-objective optimization problem is established to express in a Pareto matrix. Finally, the compatibility between the multi-objective optimization and grid valley charging is analyzed. The simulation results show that: (1) The convexity electricity price scheme can satisfy the requirements of various retention rates to achieve the valley-filling effect; (2) The filling effect is satisfied with the electricity price scheme that minimizes the charging cost, and the key factors affecting the filling effect are analyzed; (3) The multi-objective optimization scheme with charging cost and battery life is compatible with the valley-filling effect.
