Outline
The rapid increase in the proportion of renewable energy in the East China Power Grid System and the continuous decline in the rotational inertia and frequency modulation resources in the system will pose a threat to the system's frequency immunity and stability. The existing research focuses on the development and application of renewable energy system inertia and primary frequency modulation technology，while there is less research on the medium and long-term development priorities of multiple renewable energy frequency response technologies such as wind power，photovoltaic，and energy storage. Therefore，a research on the evolution path of collaborative frequency modulation technology in the East China Power Grid System was proposed. Firstly，based on the disturbance events of the East China Power Grid over the years，the system's multi-source collaborative frequency response system was analyzed，and the influencing factors of various frequency modulation entities in the disturbance events were quantitatively analyzed by decision-making trial and evaluation laboratory（DEMATEL）model. Secondly，the development priority and optimal evolution path of collaborative frequency modulation technology in East China Power Grid were prospectively analyzed based on the weight distribution of influencing factors，providing a theoretical basis for the orderly development of renewable energy frequency modulation technology in East China Power Grid. This has consolidated the frequency security of the East China Power Grid under the high proportion of new energy feeds.
