Core Viewpoint - The article highlights the successful data results from the Daqing base of the National Photovoltaic and Energy Storage Experimental Platform, focusing on the performance of various energy storage products and systems, and their implications for the development of new energy systems in China [1][2]. Summary by Sections Data Results Overview - The Daqing base has published its third complete year of data collection and analysis, optimizing statistical dimensions and methods based on expert feedback, and establishing relationships between environmental characteristics and product performance [2]. Energy Storage Product Performance - After three years of operation, the efficiency of lithium battery energy storage systems has shown a slight decline, with 1C lithium iron phosphate efficiency above 94% and system efficiency above 74% [4]. - The performance data for different types of energy storage batteries in 2024 indicates a slight decrease in efficiency compared to previous years, with specific figures for lithium iron phosphate and ternary lithium batteries detailed in a table format [5]. Technical Improvements - The article notes significant improvements in energy storage efficiency due to technological iterations, with the first-year cycle efficiency of 0.5C lithium iron phosphate increasing from 94.99% to 96.07% [7][8]. System Performance Insights - The energy storage system's efficiency is influenced by environmental temperature, achieving a maximum system efficiency of 80% at temperatures between 0-5°C, while dropping to 70% at temperatures above 25°C [8]. - The Daqing base has implemented a dynamic threshold control strategy for energy storage systems, resulting in improved performance under cloudy conditions, with a utilization rate of 22.5% [15]. Capacity Utilization - The effective utilization hours for different system capacities are reported, with a 5 MW system achieving 2919 actual effective utilization hours against a theoretical 3017 hours, and a 10 MW system achieving 2361 hours against a theoretical 2430 hours [17][18]. Future Directions - The Daqing base aims to continue supporting the high-quality development of the photovoltaic and energy storage industry through data-driven insights and technological innovations, with plans for further experimental work in different climatic regions [2].
