A Study of Hydrogen Generation with Doubly-Fed Adjustable Speed Wind Generator

A Coordinated Control Method for Integrated System of Wind Farm and Hydrogen Production: Kinetic Energy and Virtual Discharge Controls

“…The proposed coordinated controller enables us to produce hydrogen constantly in the HPS with a low-rated power. The advantage of the proposed coordinated control is verified by a comparative analysis with the methods proposed in [11] [12], and [16] through simulations.…”

“…Nevertheless, it is difficult for an ESS to store the excess power of the WF for a long time due to the limited energy capacity of the ESS. In addition, an overperformance ESS is usually used since the rated power and the energy capacity of the ESS cannot be designed independently [11].…”

“…There exist two types of systems composed of the HPS and the REPG, such as the WF, i.e., stand-alone systems [20]- [23] and grid-connected systems [11], [12], [16], [24]- [30]. In the stand-alone system where the HPS and the WF are disconnected from the grid, hydrogen can be produced without considering the power quality in the power system.…”

“…Nevertheless, mitigation of the WF output was not investigated. Smoothing control methods using HPS for the REPG, such as the WF and photovoltaics, were proposed in [11] [12], and [16]. These methods mitigate the output fluctuation of the WF without using the FC and the ESS.…”

A Calculation Method for Power System Frequency Deviation Considering Intensity of Turbulence

“…As a result, if a generator is connected as is to the electric power system, the problem of frequency fluctuations or voltage fluctuations may occur. A variety of analyses [1][2][3] have been performed to suppress system frequency deviations and combine energy storage systems and hydrogen production equipment in a power system in order to address the problem of frequency deviation. However, these analyses have primarily used real-time simulations, and as a result, substantial amounts of time are required to perform them.…”
