Stability analysis and control of power systems for the access of a high proportion of renewable energy
面向高比例可再生能源接入的电力系统稳定性分析与控制

摘要

随着高比例可再生能源的接入，电力系统面临着频率波动、电压波动等稳定性问题。为应对这些挑战，需求响应和储能技术成为关键解决方案。需求响应通过灵活调节用户负荷，平衡电力供需差异；而储能技术则通过储存过剩电能，并在需求高峰时释放，平滑可再生能源的波动。智能电网技术的应用进一步提升了电力系统的调度能力和稳定性。综合这些技术手段，有助于提高电力系统的可靠性，为高比例可再生能源的接入提供支持，确保电网的安全与经济运行。

Abstract

With the access of a high proportion of renewable energy, power systems are faced with stability issues such as frequency fluctuations and voltage fluctuations. To address these challenges, demand response and energy storage technologies have become key solutions. Demand response balances the differences between power supply and demand by flexibly adjusting user loads. Energy storage technology, on the other hand, stores excess electrical energy and releases it during peak demand periods to smooth out the fluctuations of renewable energy. The application of smart grid technology further enhances the dispatching capability and stability of power systems. The comprehensive use of these technical means helps to improve the reliability of power systems, provides support for the access of a high proportion of renewable energy, and ensures the safe and economic operation of the power grid.
