英文摘要: Clean energy and renewable energy are the important power type in modern power system, the micro grid is applied to smart grid extensively in the future. In this context, the load modeling including micro power is changed into a new challenge, because the model must has the characterization of space diversity and temporal discontinuity of micro power. Load modeling containing a variety of micro power and its interaction to voltage stability of grid is especially worthy of in-depth study as the basic problem of power grid safe operation. The complicated load model containing a variety of micro power is the basis to the task firstly. the load static and dynamic models and parameters identification are the focus secondly .The thirdly, the effect law of various micro power to complicated load model is studied in order to improve and perfect the model structure. In the end, voltage stability parameters and its interaction mechanism are analysed, so as to provide theoretical support and prevention system on power grid operation.
