“…In a 2015 study by Ali et al [13], the value of flexible domestic heating demand was highlighted as a method by which higher penetration of wind generation in the system could be accommodated. Studies by Lund et al [14] and Guille et al [15] emphasized that, during generation hours, the controlled charging of electric vehicles can provide ample benefits.…”

Abstract:From an environment perspective, the increased penetration of wind and solar generation in power systems is remarkable. However, as the intermittent renewable generation briskly grows, electrical grids are experiencing significant discrepancies between supply and demand as a result of limited system flexibility. This paper investigates the optimal sizing and control of the hydrogen energy storage system for increased utilization of renewable generation. Using a Finnish case study, a mathematical model is presented to investigate the optimal storage capacity in a renewable power system. In addition, the impact of demand response for domestic storage space heating in terms of the optimal sizing of energy storage is discussed. Finally, sensitivity analyses are conducted to observe the impact of a small share of controllable baseload production as well as the oversizing of renewable generation in terms of required hydrogen storage size.

“…With regard to P min and ramping improvements are smaller. 14 For GER 2030, parameter changes compared to last trip charging are in the same range as for CA values. Only the peak reduction is lower because the GER peak load occurs in the evening.…”

“…Delaying charging into nighttime hours could help to overcome these issues, but will probably result in higher marginal emissions [12][13], which is contrary to the original principle of clean transportation. The possible contribution that EVs could make to integrate electricity from renewable energy sources (RES-E) which is discussed by [14], [15] and [16] therefore becomes a key research question. The parameters used to quantify the contribution of technologies to integrate RES-E are the reduction of ramp rates [17] as well the correlation between RES-E and electricity demand [18].…”

Based on this method describing the fluctuation and residual load, the potential contribution of grid-connected vehicles to balancing generation from renewable energy sources is analyzed for a 2030 scenario using the agent-based simulation model PowerACE. The analysis reveals that integrating fluctuating RES is possible with less effort in California because of a higher correlation between RES generation and the load curve here. In addition, RES capacity factors are higher for California and therefore the ratio of installed capacity to peak load is lower. Germany, on the other hand, faces extreme residual load changes between periods with and without supply from RES. In both power system scenarios, grid-connected vehicles play an important role in reducing residual load fluctuation if smart charging is used. Uncontrolled charging or static time-of-use tariffs do not significantly improve the grid integration of RES.

“…The ability to consume unused electricity through overnight charging creates a mutually beneficial relationship between electric vehicles and wind power (greatly reducing the need for storage or transfer). In addition, Lund and Kempton (2008) show that vehicle to grid technology will improve the efficiency of the electric power system, lower carbon emissions and improve the integration of wind power. In order to achieve significant carbon reductions, policy measures must move significantly beyond current practice and level of application, as also recognised by Hickman et al (2010).…”
