Abstract

The invention provides a power system simulation method, a power system simulation device and an electronic device, which relate to the technical field of power system simulation. The power system simulation method comprises the following steps: a, calculating the internal electric quantity of each division of the power system; b, calculating the node injection history current vector according tothe internal electric quantity of each partition; c, calculating Thevenin equivalent impedance and Thevenin equivalent voltage at the boundary node of each zone according to the node injection historycurrent vector; d, calculating the tie line current of each zone at the current time according to the Thevenin equivalent impedance and Thevenin equivalent voltage at the boundary node of each zone;and e, acquiring the node injection history current vector calculated in the step b of each partition, calculating the tie line current and the node admittance matrix at the current time in the step d, and returning to the step a. By using the above methods, the problems of large computational load or low precision in the existing power system simulation technology can be improved.

Description

technical field [0001] The present invention relates to the technical field of power system simulation, in particular to a power system simulation method, a power system simulation device and electronic equipment. Background technique [0002] With the large-scale development of renewable energy and the rapid development of UHV AC-DC transmission technology, the new-generation power system presents the characteristics of rich types of power sources and complex forms of power conversion. On the power generation side, large-scale renewable energy sources such as wind power and photovoltaics are integrated into the traditional AC power grid through converters; on the power transmission side, the western energy base adopts a hybrid network of UHVDC and UHVAC Power transmission to the Sanhua area; on the power distribution side, a large number of distributed power sources form a micro-grid system through the interface of the converter, and gradually form an active distribution ne...
