“…Thus, the type and capacity of energy storage to be used must be carefully selected. Energy storage systems must have either fast response parts or a certain amount of energy storage capacity to meet the demands of load and generation adjustments and to improve the performance of RESs [6]. A single energy storage device cannot satisfy these requirements.…”

“…Thus, a superconducting magnetic energy storage (SMES) system, which can act as a good tool for considerably decreasing the power fluctuations of the wind generator system, was used [12][13][14][15][16][17][18]. The overall control of the microgrid power system was performed using the control and monitoring system (CMS) [6].…”

“…The SOFC supplies additional power to the microgrid system when the wind power is insufficient, and the SMES stabilizes tie-line power fluctuations. In this paper, the standard deviations of wind power PWP and random load deviation P Load were mathematically evaluated as follows [6]:…”

Wind power causes fluctuations in power systems and introduces issues concerning system stability and power quality because of the lack of controllability of its discontinuous and intermittent resources. This paper presents a coordinated control strategy for solid oxide fuel cells (SOFCs) and superconducting magnetic energy storage (SMES) to match the intermittent wind power generation and compensate for the rapid load changes. An optimal H∞ control method, where the weighting function selection is expressed as an optimization problem, is proposed to mitigate tie-line power fluctuations and the mixed-sensitivity approach is used to deal with the interference suppression. Simulation results show that the proposed method significantly improves the smoothing effect of wind power fluctuations. Compared with the conventional control method, the proposed method has better anti-interference performance in various operating situations.

Hydrogen could become an important energy carrier, in particular used as an input to fuel cell electric vehicles. Alkaline electrolysers are an attractive technology to produce carbon-free hydrogen from renewable generated electricity. Largescale alkaline electrolysers used in future hydrogen-filling stations could also be utilised to improve the frequency stability of the electricity power system. The electrolyser load can be controlled to respond to power system frequency variations, and in the case of a sudden loss of generation, these electrolysers could rapidly decrease their load on the system to maintain the power balance. In this study, the potential of alkaline electrolysers to dynamically stabilise the frequency of the power system is assessed. A model of steam turbine generation unit has been developed in MATLAB SIMULINK environment, and a scenario in which there is a sudden loss of generation in the system is examined. It is demonstrated that alkaline electrolysers could prevent unacceptable frequency drop, i.e. below the statutory limit, following by an abrupt loss of generation, even with no spinning reserve on the system. In this article for the first time, the ramping rate of an alkaline electrolyser is shown through experimental data.
