Special Session 9

Build a new type of power system with new energy as the main body, it is the core path of the global energy transition. Renewable energy sources such as wind power and solar power have significant characteristics of intermittency and volatility. Its integration through power electronic devices will also lead to problems such as a decrease in system inertia and a reduction in the voltage and frequency support capabilities. This poses a serious challenge to the safe and stable operation of the power grid. The rapid development of energy storage technology, it provides a key technical path for stabilizing power fluctuations in the power grid and enhancing its flexible regulation capabilities.
However, the grid connection standards for energy storage stations emphasize their ability to actively support the power grid. Propose technical indicators such as rapid frequency response and dynamic voltage regulation. Some scenarios require that the station have the capability of forming a network. In this context, the precise modeling and comprehensive testing of new energy and energy storage stations are necessary. It becomes an essential foundation for ensuring the safe and efficient grid connection and supporting the stable operation of the new power system. Therefore, a special discussion session was set up.

构建以新能源为主体的新型电力系统，是全球能源转型的核心路径。风电、光伏等新能源发电具有显著的间歇性与波动性，其通过电力电子装置并网还会带来系统惯量降低、电压与频率支撑能力减弱等问题，给电网安全稳定运行带来严峻挑战。储能技术的快速发展，为电网平抑功率波动、提升灵活调节能力提供了关键技术路径。
然而储能场站的并网标准强调主动支撑电网，提出快速频率响应、动态电压调节等技术指标，部分场景要求场站具备构网型运行能力。在此背景下，新能源与储能电站的精确建模和全面测试，成为保障其安全高效并网、支撑新型电力系统稳定运行的重要基础。为此设置专题研讨。
