Description

technical field [0001] The invention relates to the field of distribution network, in particular to a memory, a control decision method, system and device of a power system of a distribution network. Background technique [0002] The distribution network refers to the power network that receives electric energy from the transmission network or regional power plants, and distributes it locally through power distribution facilities or distributes it to various users step by step according to voltage. [0003] Power system simulation is to establish a model based on the original power system, use the model to conduct calculations and experiments, and study the working behavior and characteristics of the power system within a specified time. Power system simulation plays an important role in the planning, design, construction and operation of power systems. Digital simulation is not limited by the size and structure complexity of the system being studied, and has fast calculati...
