“…Studies [32][33][34][35], which provide results on optimising the size and placement of the energy storage system with the aim of further increasing the economic efficiency and competitiveness of the system as a whole [26,36,37], are of great importance. Paper [38] proposes a method for determining the optimal location and size of a battery energy storage system to reduce voltage fluctuations and total active losses in the distribution system, and study [39] analyses the economic benefits of integrating energy storage systems with wind generation to maximise revenues.…”

During the operation of solar and wind power plants, it is necessary to solve issues related to the guaranteed capacity of these plants, as well as the frequency stabilisation in the power system where they operate, and maintain an operating mode of self-sufficiency conditions. One of the solutions to these problems is the use of energy storage systems. This article proposes a mathematical model for the study of frequency and power regulation processes in power systems with distributed generation, which includes renewable energy resources and energy storage systems. The novelty of the model lies in the possibility of determining energy cost indicators based on instantaneous energy power data. The model allows us to estimate the conditions under which distributed generation becomes self-sufficient. The results of the model calculations of two variants of power system operation, which includes wind generators with a capacity of 1500 MW, demonstrate the ability of the proposed model to accurately reproduce the dynamics of the frequency stabilisation process. The calculation results of the energy-economic indicators of a real power system combined with a powerful subsystem of wind generation and a battery-type energy storage system prove the competitiveness of self-sufficient renewable energy power plants.

Benefiting from the high sensitivity and electromechanical conversion efficiency, triboelectric nanogenerators (TENGs) are widely used in various fields of self‐powered sensing and mechanical energy harvesting, which have great potential for application in future smart Internet of Things. The development of sustainable triboelectric materials with high‐performance has a vital impact on the construction of TENG devices that combine high‐output performance and environmental friendliness, which have a positive impact on the sustainable development of humanity. This review systematically and comprehensively summarizes the latest research work on TENG's sustainable materials. First, an overall overview is provided based on the composition of the materials, including amino acids, polysaccharides, and synthetic polymer, and the representative research works are further classified and summarized in detail. In addition, the latest research progress of TENG with sustainable materials in the fields of self‐powered sensing and mechanical energy harvesting applications is also summarized. Finally, the overviews are provided for the various challenges in the current development of TENG's sustainable material, and the related outlooks are offered on the corresponding development strategies and directions of this field in the future.

The implementation of sodium metal batteries (SMBs) is known for their low cost and high energy density. However, a major concern in SMBs is the formation of dendrites on the Na metal anode, which can potentially cause short circuits and compromise safety. Herein, to address this issue, we propose a novel approach to create a protective layer by decorating Na surface with NaI particles. This protective layer exhibits a high Young’s modulus and excellent sodium ion transference ability. As a result, the lifespan of the Na/NaI||Na/NaI cell is significantly extended to 850 h at 0.5 mA cm−2/1 mAh cm−2. Furthermore, when the Na/NaI anode is combined with a Na3V2(PO4)3 (NVP) cathode, the full cell retains 83 mAh g−1 (approximately 94% of its initial capacity) even after 1500 cycles at 5 C. Overall, this work presents a simple and effective method for establishing a protective layer on the Na surface, thereby enabling the realization of long lifespan and stable SMBs.
