“…9,10 Many studies have described and analyzed the economic feasibility of hydrogen storage, 7,[11][12][13][14] with common topics including improving efficiency, reducing high investment costs, addressing uncertain profitability, and increasing storage. In addition, the capacity optimization of wind-hydrogen systems has been studied on the electrolyzer 15,16 and fuel cell. 16 These previous papers focusing on technical and economic analyses serve as a useful research foundation for this paper.…”

Summary In general, wind power output of clustering wind farms must be massively transmitted. The wind power in each wind farm is correlated, intermittent, fluctuant, and cannot be accommodated all the time, causing the intractable decision of economical transmission capacity of a project transmitting wind power to a power grid. Furthermore, the drastic fluctuation of clustered wind power results in enormous challenges regarding the safety of a power system. For these reasons, the concept of a wind‐hydrogen power system for clustered wind farms is proposed. Next, a multiobjective model for optimizing the capacities, including the transmission project, hydrogen‐producing system, and fuel cells, is constructed based on the joint distributed character of wind speed, which consists of maximizing social benefit and the qualified rate of smoothing clustering wind power fluctuations. Finally, a case is analyzed in detail, accounting for the wind volatility, wind curtailment probability, and the costs of both hydrogen production and the fuel cells.

“…The regulated power from the load-side under the impact of module's saturated state can be characterized by (22). It shows the equivalent system damping compared to (21) is reduced due to some modules operating in the saturated state. But the equivalent damping is larger than the case without DFR, thereby still improving the frequency response to some extent.…”

“…A few works explore the possibility of electrolyzers on mitigating the fluctuation caused by RES variability to secure grid stability [21], [22], but lack of frequency response analysis. To clarify the frequency support capability from electrolyzers, the authors utilize large-scale AELs as demand-side flexible resources to improve frequency stability of a wind-dominated power system (WPS) [23], but does not give references to detailed modeling and control of AELs.…”

Integration of the hydrogen sector into power systems via electrolyzers could greatly facilitate energy sustainability by producing green hydrogen, moreover, assist in reinforcing frequency stability based on optimal control of electrolyzers. In order to improve the frequency performance of the wind-dominated electricity-hydrogen systems (WEHS), this paper investigates how to analytically evaluate and implement the dynamic frequency regulation (DFR) supported by a grid-scale alkaline electrolyzer (AEL) plant. The DFR's potential of the AEL plant is released by an emulated power-frequency characteristic, and its contributions to improving system frequency response are also analytically evaluated from the aspects of transient, steady-state, and stability indicators. Furthermore, the DFR dependency on the frequency containment reserve provision and pre-contingency operating points of AELs are analytically clarified. A DFR-driven controller to coordinate multiple modules in the AEL plant is also designed in detail. In addition, the economic analysis is presented to evaluate the profitability of AELs providing frequency support. Cases of a simple WEHS and a modified IEEE 9-bus system integrated with grid-scale AEL plants during frequency contingencies are studied to validate the proposed DFR method, which can improve the system frequency response with smoother transients and lower steady-state deviation. Index Terms-Alkaline electrolyzer, analytical evaluations of frequency response, grid-scale electrolyzer plant, system frequency support, wind-dominated electricity-hydrogen systems.

“…Wind turbines can also be combined with an ES unit in a wind-ES configuration. In such a configuration, the ES, which is in the form of a battery, is used to stabilise fluctuation associated with wind power (Xu et al, 2018), in addition to providing storage for the excessive generated power (García Clúa et al, 2018). The viability of consumer-based small-scale wind turbines for consumers in South Africa has been studied by Whelan and Muchapondwa (2011).…”

Many countries, including South Africa, have introduced policies and incentives to increase their renewable energy capacities in order to address environmental concerns and reduce pollutant emissions into the atmosphere. In addition, consumers in South Africa have faced the ever-increasing price of electricity and unreliability of the grid since 2007 due to the lack of sufficient electricity production. As a result, employing hybrid renewable energy systems (HRESs) have gained popularity. This research focuses on grid-connected HRESs based on solar photovoltaic (PV) panels and wind turbines as a potential way of reducing the dependency of residential sector consumers on the grid. It aims to identify the optimal sizing of renewable energy sources to be cost-effective for consumers over a certain period of time, using Durban as a case study. Two artificial intelligence methods have been used to obtain the optimal sizing for the available PV panels, wind turbines and inverters. The results shown that the combination of PV panels and battery storage can be a profitable option. A system using higher rated power PV panels can start to become profitable in a shorter lifetime, but employing batteries can only be cost-effective if a long enough lifetime is considered.
