Problems solved by technology

[0002] The calculation of power system node voltage is the core work of design and operation control of power system structure, power distribution, instantaneous power flow voltage value, etc. It is found that when calculating the node voltage of the power system, there are large differences in node selection and settlement methods. The process is responsible and the versatility is insufficient, which seriously affects the actual application effect of the power system node voltage calculation results. Therefore, in view of this situation, it is urgent to develop a new power system node calculation method to meet the needs of actual use.
