摘要
为促进能源转型、优化能源结构,我国可再生能源在电力系统中的占比不断增加。但新能源机组发电具有随机性、波动性,其并网会给电网的安全稳定运行带来负面影响。电化学储能技术具有快速响应、灵活调节系统功率的特性,为电力系统的安全稳定运行提供了保障。介绍了储能技术的类型以及目前已落地的电化学储能工程项目;分别从频率稳定、静态电压稳定以及暂态电压稳定3个方面阐述了储能在电力系统稳定控制中的作用;对电动汽车换电站以及电动汽车参与电力系统调节进行了展望。储能将成为电力系统的关键组成部分。
In order to promote energy transformation and optimize energy mix of China,the proportion of renewable energy in the energy mix has been increasing.However,the randomness and volatility of renewable energy generation brings negative impact on the safe and stable operation of power grid.Since electrochemical energy storage technology has the characteristics of rapid response and flexible power adjustment,it facilitates the safe and stable operation of power grid.Firstly,the types of energy storage technologies and completed electrochemical energy storage projects are summarized.After that,the role of energy storage in power system stability control is explained from three aspects:frequency stability,static voltage stability and transient voltage stability.Finally,the expectation on the participation of electric vehicle charging stations and electric vehicles in power system regulation is made.Energy storage technologies will be the key component of power systems.
