The method comprises the steps: according to different types of power grid data, establishing different types of object models, the different types comprising a generator, a load, a line and a transformer; performing Hash mapping on the different types of object models and memory computing nodes; and performing distributed parallel memory calculation on the different types of object models in a memory data network according to the memory calculation nodes.

Description

technical field [0001] The present application relates to the technical field of large power grid security, in particular to a method and system for online modeling of power grids based on memory computing architecture. Background technique [0002] The scale of the modern power grid is expanding day by day, more and more UHV AC and DC transmission lines are connected to the power grid, FACTS facilities are widely used, and the operation mode and characteristics of the power grid are becoming more and more complex. The large-scale access to the power grid with wind power and photovoltaic new energy, the increasing abundance of various demand-side response resources at the power consumption end, and the rapid development of electric vehicles have greatly enhanced the randomness and volatility of the power system. [0003] The operation mode and dynamic characteristics of the power grid are becoming more and more complex and changeable. The power system dispatching department ...
