A Study On Total Transfer Capability Of Electric Power System Based On Power Distribution Character

Transfer capability as a performance indicator is an important measurement of security and reliability,reflects connection strength and structure merits directly,and is an important reference for power grid planning.With the development of the electic power market,total transfer capability is the research key point.The application of sensitivity analysis method in total transfer capability research is firstly detailed.The power distribution character is analyzed so as to find out the relation between the transmission power and the generator injection power.The linear relationship between the generator injection power and its transmission power component in a line is derived from the power distribution character,when those three assumptions of the classic economic dispatch B coefficient method was applied,and a simulation example is used to verify the existence.Finally,the calculation model and calculation steps of total transfer capability of power system are aet up based on the new linear relationship,and validated through a simulation example.
