| Abstract: | Driven by the goal of "carbon peak，carbon neutrality" and "building a new power system with new energy as the main body"， the connection of high proportion new energy will aggravate the instability of power system oscillation. This paper comprehensively considers the various parts of the power system，such as photovoltaic cells，converters， inverters and synchronous condensers， and establishes an accurate overall model of the photovoltaic power generation grid-connected system. Based on the mode analysis method， the method for synchronous condensers to suppress sub-synchronous oscillation in the power system is analyzed and explored. The correctness and feasibility of the method are verified by IEEE sub-synchronous oscillation first standard simulation. Finally， the simulation analysis and verification are carried out on the Matlab software platform. The results show that the proposed method can effectively eliminate oscillation and improve system stability. |
