Renewable energy (RE) is green and low-carbon energy, which can not only protect the environment, promote the technological diversification of the energy supply system, accelerate the adjustment of energy structure, but also has important significance for the sustainable development of economy. With the increasing complexity of the problems of renewable energy system asset management and ensuring the operational reliability of electric power equipment, it's necessary to establish remote, online, reliable monitoring and inspection techniques for the state evaluation of electrical equipment during the full life cycle. In order to meet these demands, the digital twin is a very suitable technology. In recent years, there are numerous scientific papers demonstrating DT's capabilities in virtual simulation, condition monitoring (CM), power optimization and fault diagnosis for RE generation systems, transmission and transformation equipment and storage systems. The majority of the research focusing on product design, maintenance of operation, condition monitoring and fault decision-making has provided many valuable contributions to academia and industrial fields. Nevertheless, all this valuable information is scattered over many literatures and it is lack of systematic generalization. In this article, different applications of DT technology in RE system are analyzed, advanced methods and theories are summarized comprehensively, and the development trend of DT technology in renewable energy system in the future is introduced.

“…With the rapid development of technologies such as big data, cloud computing, and the Internet of Things, in some fields, traditional simulation systems that convert uncertainty at a specific level into its impact on the target by building specific models are no longer able to meet relevant requirements [1][2][3]. For example, the simulation of secondary measurement and protection systems, automatic devices, and monitoring systems in power substations cannot use accurate mathematical models to simulate various operating conditions of different protection devices in real time.…”

At present, there are problems in the process of fault location and cause analysis in the actual work of substations, such as long time consumption, high investment in manpower and material resources, and low returns. A Digital Twin (DT) system construction method that can be used for virtual mapping in substations is proposed to address this problem. Firstly, the design principles and overall structure of the substation DT system were formulated by comprehensively considering the needs of transient modeling, debugging, and verification calculations in the substation. Then, the construction method and process of the three-dimensional twin model of the primary system (PS) in the substation were analyzed by using SolidWorks and Unity3D, and the graphical modeling method and process of the general protection and secondary circuit logic modules were analyzed by using the Cybersim integrated simulation support system. Finally, a three-dimensional twin model of the PS and secondary system (SS) equipment inside the substation was constructed. The reliability of the proposed method was verified through simulation experiments, and the results showed that the fault identification accuracy, fault location accuracy, and fault cause judgment accuracy were the highest during bus faults, with 96.10%, 94.17%, and 92.93%, respectively. The capacitor had the lowest accuracy, with 94.86%, 92.96%, and 91.73%, respectively. The DT system can accurately achieve functions such as status viewing and alarm of the substation, precise positioning and navigation of equipment, and positioning of faulty and abnormal equipment.

“…The Bei Hang research team proposed a five-layer architecture of digital twin i.e., physical entity, virtual entity, data, connection, and service [3]. Based on the experience with digital twin technology in real power stations, it is known that the construction of 3D models for monitoring equipment also becomes a part of the digital twin concept [4]. The virtual entity in the power digital twin system is the construction of twin models of physical entity in digital space through digital modeling technology, which is the cornerstone of the power digital twin.…”

The digital twin is one of the key technologies driving the digital transformation of power equipment, providing new opportunities for the construction of new power systems. As an important transmission and transformation equipment in the power system, high-voltage converter stations can be monitored by multi-physical quantity sensing technology to ensure reliable operation of the converter valves. The key issue is therefore how to obtain the operating state of the multi-physical quantities in the valve hall. To this end, this paper studies a three-dimensional twin model for the converter valve based on the advantages of the digital twin five-dimensional model and visualizes the operating temperature and pressure states in the valve hall through the sensor monitoring data, showing that the results are of some significance for the deployment of multi-physics sensors and the stable operation of the converter valve.
