The frequency regulation capability of wind turbines is insufficient to satisfy the needs of grid frequency regulation. The characteristics of energy storage， such as flexible control， substantial throughput capacity， and rapid response rates， can effectively complement wind turbine limitations. Thereby， these facets advocate for incorporating an integrated wind-and-storage system in the practice of grid frequency control. This paper delves into the principles and control strategies associated with the participation of wind turbines and energy storage in the regulation of power system frequency. It outlines the principles and features of energy storage participating in frequency regulation， as well as models for frequency control and the control strategies. Moreover， the paper scrutinizes the characteristics and effects of different and hybrid energy storage systems. Subsequently， it elucidates the principles of frequency control for wind turbines and various control strategies， classifying the control modes of wind turbines into： variable-pitch control， rotor kinetic energy control， and unified control. In conclusion， the current state of advancements and prospects in this field are summarized and envisioned.

Essentially, the top priority of political theory teaching reform and innovation in military academies is to fully implement the military education strategies of the new era, and to focus on the fundamental task and core direction characterized by fostering virtue through education and training talents for warfare. In this regard, this paper explores the construction of the “main classroom+” practice teaching model of political theory course from four dimensions, encompassing “thematic practice”, “professional customization”, “comprehensive exercise”, and “practice expansion”, intending to provide feasible paths and methods for military academies to realize more effective integration of theory and practice of political theory teaching in the new era.

Red music during the Agrarian Revolutionary War was rooted in the leadership of the Communist Party of China and grew up in the revolutionary struggle. Based on a study of the background, style and effect of red music in this period, this paper discusses the role of red music in propagating revolutionary theories, mobilizing the masses and inspiring people during the founding and development of revolutionary bases such as Jinggangshan Mountain, Central Soviet Area and Shaanxi-Gansu Border.

On the basis of sorting out the development history of artificial intelligence technology and its status quo in military application, the paper discussed the challenges in military application of artificial intelligence technology in information warfare, constructed a framework for the application of artificial intelligence in the field of military information, and put forward constructive thoughts and suggestions on how to accelerate the intelligent application in the field of military information.

To study the effect of the precuring rate of impregnated fluffed veneers (IFVs) on the bonding performance of scrimber, the precuring rate of IFVs following different drying conditions was characterized by fluorescence microscopy. The phenol formaldehyde (PF) solid content, drying temperature, and time were assessed using orthogonal tests. The moisture content, precuring rate of the dried IFVs, and bonding strength of the scrimber were evaluated. The results showed that the moisture content of the IFVs was mainly affected by the PF solid content, while the precuring rate of the impregnated IFVs was primarily impacted by the drying temperature. A solid PF content of 20% and optimum drying conditions of 60 °C and 1.5 h were associated with a precuring rate of 12.3% of the PF resin on the surface of the IFVs, obtaining scrimber with the best bonding performance of 2.95 MPa.
