The invention relates to a modeling and
analysis method in the field of electrical power
system modeling and simulating, in particular to a power
distribution system multi-dimensional multi-resolution modeling and
analysis method. According to the power
distribution system multi-dimensional multi-resolution modeling and
analysis method, one or more standard values are selected, the multi-dimensional resolution of a model is composed of parameters such as the percentage of the internal
power capacity to the standard value (the internal
power capacity percentage for short) and the percentage of a load to the standard value (the
load capacity percentage for short), then conventional models of the current, the
voltage, the line losses and the like are shown in the multi-dimensional resolution mode, a plurality of resolution
modes are formed along with changes of the resolution, accordingly, a multi-dimensional multi-resolution model is built, and finally electrical characteristics such as the current, the
voltage and the line losses in the
system are analyzed based on the model. According to the power
distribution system multi-dimensional multi-resolution modeling and analysis method, the
multiple models with different resolutions are mutually connected in a joint environment, dynamic characteristics in a power distribution
system are jointly reflected from multiple angles and multiple
layers, and accordingly the simulating efficiency and the simulating quality are improved.
