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.
