Temporary power frequency overvoltage in power systems integrated with high proportion of renewable energy is a key factor that affects the system security and restricts the renewable energy consumption. To reveal the overvoltage mechanism for the temporary power frequency
firstly
a quasi-steady-state model for a two-machine equivalent system integrated with renewable energy is built
and the peak value of the terminal voltage of renewable energy is analytically obtained based on the phasor relationship. Secondly
employing the total differential method
the relevant relationship between the terminal voltage and the current of renewable energy is analyzed
and the influence mechanism of reactive power compensation and rotor angle swinging on the terminal voltage is clarified. Furthermore
taking the preset maximum peak value as the boundary
the optimization suggestions for the current and the upper reactive power compensation limit are proposed to provide the basic theoretical support for the safe and reliable transmission of renewable energy in large-scale composite energy transmission scenarios. Finally
the photovoltaic-thermal power bundling system and the actual composite energy sending-end system are used to carry out the simulation
and the effectiveness of the theoretical analysis is verified.
