Description
Summary:	A renewable energy carrying capacity evaluation method of alternating current (AC) and direct current (DC) hybrid power grid based on minimum frequency constraint is proposed. By considering the influence of power grid disturbance power, load frequency effect, primary frequency regulation of generators, and power exchange of the interconnection line on system frequency change, the formula of the renewable energy carrying capacity of the AC-DC hybrid system is derived, and the sensitivities of the relevant influencing factors are analyzed. Besides, the enhancement effects of DC power support and energy storage device on the renewable energy carrying capacity are further analyzed, and finally the validity of the proposed method is verified by taking Central China power grid as an example.
