- With the enlargement of power grid scale, connections between different power subsystems in interconnected network have been more-closely related and the analysis of power system dynamic behaviors becomes more complex. This paper selects 3 area indexes which comprehensively reflect frequency change through transient process based on transient frequency stability curve and frequency change ratio curve, and there out builds the quantitative assessment method of frequency fluctuation characteristics. Then a generator set speed governor magnification-targeted optimization model, which determines the optimum of frequency fluctuation characteristics as optimal objective with proposed indexes, is built and solved by multivariate optimization algorithm. At last, an optimal example of practical power grid verifies the feasibility and validity of the proposed assessment method and the optimization model.
