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.
