Description

technical field [0001] The invention relates to the technical field of new energy power generation grid connection and operation control, in particular to a system and method for online monitoring and analysis of new energy network source coordinated frequency modulation and inertia support. Background technique [0002] With the gradual commissioning of UHV projects and the rapid growth of new energy installed capacity, the random fluctuation characteristics of wind energy, solar energy and other new energy sources will directly affect the safe and stable operation of the power grid. [0003] On the one hand, the power grid needs to absorb new energy and maintain the balance between supply and demand of the power system. On the other hand, it has become an inevitable trend of development to require new energy to participate in the daily regulation and control of the system.
