储能技术在可再生能源并网中的作用与策略
摘 要
随着全球对环境保护和可持续发展的重视，可再生能源的开发利用已成为国际社会的共识。然而，可再生能源发电具有间歇性和不稳定性，对电网的稳定运行带来了挑战。储能技术作为一种能够有效平衡供需波动、优化能源配置的手段，在可再生能源并网中发挥着越来越重要的作用。本研究针对储能技术在可再生能源并网中的作用与策略进行了全面分析。首先，介绍了储能技术的定义、分类及其在电网稳定性、能量管理、可再生能源消纳等方面的基本作用。其次，详细探讨了储能系统的选型、布局、运行策略以及经济性分析，为储能技术的实际应用提供了科学指导。最后，结合中国可再生能源发展的现状，以青海省光伏发电与储能系统结合的实践为例，深入剖析了储能技术在可再生能源并网中的实践效果与挑战。研究结果表明，储能技术对于提升可再生能源并网效率、优化能源结构、促进节能减排等方面具有重要意义，但当前仍存在技术瓶颈、政策障碍和市场挑战，需要进一步完善政策支持、市场机制和技术创新体系。

Abstract
With the global emphasis on environmental protection and sustainable development, the development and utilization of renewable energy has become the consensus of the international community. However, renewable energy generation is intermittent and unstable, which brings challenges to the stable operation of the power grid. Energy storage technology, as a means to effectively balance the fluctuations of supply and demand and optimize energy allocation, is playing an increasingly important role in the grid connection of renewable energy. In this study, the role and strategy of energy storage technology in renewable energy grid connection are comprehensively analyzed. First, the definition and classification of energy storage technology and its basic role in power grid stability, energy management, renewable energy consumption and other aspects are introduced. Secondly, the selection, layout, operation strategy and economic analysis of the energy storage system are discussed in detail, which provides scientific guidance for the practical application of the energy storage technology. Finally, combined with the current situation of renewable energy development in China, taking the practice of combining photovoltaic power generation and energy storage system in Qinghai Province as an example, the practical effects and challenges of energy storage technology in the grid connection of renewable energy are deeply analyzed. The research results show that energy storage technology is of great significance for improving the grid connection efficiency of renewable energy, optimizing energy structure and promoting energy conservation and emission reduction, but there are still technical bottlenecks, policy obstacles and market challenges, which need to further improve the policy support, market mechanism and technological innovation system.
