“…This is not examined here, but may be covered in future work. It was shown in [13] that at lower levels of wind, storage would probably not compete economically, based on prices on the Irish system expected in 2020.…”

“…While storage at lower levels of wind power may be seen to be uneconomical purely from a fuel cost basis [11], [13], it seems clear that, at some point, if a large enough amount of wind is installed, the amount of wind curtailed on the system means that it becomes sensible to have storage to reduce fuel costs, even when accounting for the round-trip efficiency 978-1-4244-4241-6/09/$25.00 ©2009 IEEE of storage. However, as storage capital costs are generally expected to be greater (needing both a generator / pump and space to store energy as water or gas), the savings made would need to be enough to ensure the system was less expensive to build as well as operate.…”

Abstract-In this paper, the unit commitment and dispatch of a power system with and without a pumped storage unit is examined for increasing levels of installed wind power, from 17% of total energy to 80% of total energy generated by wind 3 (3GW to 15GW of installed wind on the Irish system in 2020). At high levels of installed wind, it is shown that storage reduces curtailment and increases the use the base loaded plant on the system. This reduces system costs. However, when the additional capital costs of storage are taken into account, it is shown that storage is not viable from a system perspective until extremely large levels of wind power are seen on the system. At these levels of installed wind, while the system can operate without storage, it is less costly to do so with storage. The capacity credit of the storage unit is also examined, using a simplified approach, and shown to decrease as larger amounts of intermittent wind power are added to the system.

“…Hereby, the aim is not to smoothen demand peaks in an optimal way; rather, it is to gain information on the effects of storage systems at a large scale like a district in Hamburg. Feeley et al [29] and Chandio et al [28] have performed investigations on the most efficient strategies when using storage systems. The aim is to use energy storage to decrease the peaks on the demand side with the help of advanced algorithms.…”

Globally, efforts are made to balance energy demands and supplies while reducing CO2 emissions. Germany, in its transition to renewable energies, faces challenges in regulating its energy supply. This study investigates the impact of various technologies, including energy storage solutions, peak shaving, and virtual buffers in a smart energy grid on a large scale. Real-time energy supply and demand data are collected from the Port of Hamburg and HafenCity in Germany to analyze the characteristics of different technologies such as load shifting of reefer containers and private electric vehicles’ energy, as well as pumped hydro storage. Through simulations, we assess the usability of renewable energies in a smart grid with versatile energy demands and determine the effects of peak shaving, storage solutions, and virtual buffers on uncertain energy supply. Our case study reveals that integrating smart grid technologies can reduce the overproduction of renewable energies needed to prevent blackouts from 95% to 65% at the HafenCity and the Port of Hamburg. Notably, large, reliable, and predictable energy consumers like the Port of Hamburg play a vital role in managing the uncontrollable nature of renewables, resulting in up to 31% cost savings for new infrastructure.
