Size And Structure

By 2050, blue hydrogen (produced by SMR method using CCS technology to capture CO2) will make up about 18% of hydrogen supply, whilst green hydrogen from solar power will account for 16%, from onshore wind power 16% and offshore wind power 9%. Global hydrogen demand is forecasted to increase to about 150 million tons by 2040 [1].

Power Project

Many countries have increased the use of renewable energy and strongly promoted offshore wind power (OWP). However, OWP in Asia is in the preliminary stage of development, for which no precedents exist. The literature on wind energy generation has mostly investigated the causes of onshore wind turbine accidents and risk prevention, and more work on the risks associated with domestic OWP is required for energy market development. According to statistics on international wind power accidents, most offshore accidents occur in the construction and operation stages. Therefore, this work investigates risk management in the construction and operations of offshore windfarms in Taiwan. The goal is to help decision-makers to understand better the risks of the industry and so more effectively manage them. In this study, risk factors are identified from organizing data in the literature, and research methods and action strategies are developed. Research and analysis follow the risk management steps in the PMBOK® Guide (A Guide to the Project Management Body of Knowledge). The risk rankings and preventive measures that are based on the results of this study can serve as references for relevant industry personnel in island cities and nearby Asian countries to reduce risk in the management of OWP projects.

Offshore wind power is expected to increase significantly in the near future. This document use the method combined the SWOT and fuzzy comprehensive appraisal to analyze China’s offshore wind industry competitiveness. Firstly, perform qualitative analysis by SWOT and then use fuzzy comprehensive appraisal to transfer qualitative analysis to quantitative analysis for a more objective and accurate evaluation. The final evaluation results show that China’s offshore wind industry is competitive. And China should actively and steadily promote the development of offshore wind industry while should pay attention to draw experience and lessons from onshore wind power.

The Impact

With resource crisis and environmental crisis increasingly grim, many countries turn the focus to pollution-free and renewable wind energy resources, which are mainly used for offshore wind power generation, seawater desalination and heating, etc., on the premise that the characteristics of resources are fully grasped. In this study, the evaluation of offshore wind energy in offshore waters in China, as well as the advantages and disadvantages of existing studies were overviewed from four aspects: the spatial-temporal characteristics of wind energy, wind energy classification, the short-term forecast of wind energy and the long-term projection of wind energy, according to the research content and the future considerations about wind energy evaluation (evaluation of wind energy on islands and reefs, the impact of wind energy development on human health) were envisaged, in the hope of providing a scientific basis for the site selection and business operation ‘or military applications’ here (after business operation), etc. of wind energy development, ‘aritime navigation against environmental construction,’ here and also contributing to the sustainable development and health of human beings.

System Frequency

Offshore wind power has great development potential, for which the key factors are reliable and economical wind farms and integration systems. This paper proposes a medium-frequency wind farm and MMC-HVDC integration system. In the proposed scheme, the operating frequency of the offshore wind farm and its power collection system is increased from the conventional 50/60 Hz rate to the medium-frequency range, i.e., 100–400 Hz; the offshore wind power is transmitted to the onshore grid via the modular multilevel converter-based high-voltage direct current transmission (MMC-HVDC). First, this paper explains the principles of the proposed scheme in terms of the system topology and control strategy aspects. Then, the impacts of increasing the offshore system operating frequency on the main parameters of the offshore station are discussed. As the frequency increases, it is shown that the actual value of the electrical equipment, such as the transformers, the arm inductors, and the SM capacitors of the rectifier MMC, can be reduced, which means smaller platforms are required for the step-up transformer station and the converter station. Then, the system operation characteristics are analyzed, with the results showing that the power losses in the system increase slightly with the increase of the offshore AC system frequency. Based on time domain simulation results from power systems computer aided design/electromagnetic transients including DC (PSCAD/EMTDC), it is noted that the dynamic behavior of the system is not significantly affected with the increase of the offshore AC system frequency in most scenarios. In this way, the technical feasibility of the proposed offshore platform miniaturization technology is proven.
