Optimal Allocation of Installation Capacity of the Solar- Thermal Power Station Considering Transient Voltage Stability

The research on the optimal allocation of installed capacity of the solar-thermal power station is carried out for the DC (Direct Current) transmission operation scenario of new energy base. Firstly, establishes the output model of system power timing operation characteristics. Secondly, taking transient voltage stability and DC transmission capacity as objective functions, establishes the installation capacity configuration model of the solar-thermal power station based on time series production simulation, and obtain the optimal installation capacity of the solar-thermal power station. Finally, based on CPLEX, simulates the system in a certain area of Gansu Province, and obtain the optimal configuration scheme of install capacity of the solar-thermal power station. The results show that the transient voltage stability recovery index is 0.348 when configure the 100 MW the solar-thermal power station, and the voltage support ability of the system is strong. The research shows that the optimal allocation of install capacity of the solar-thermal power station can reduce the abandonment rate of wind power and photovoltaic, and improve the consumption rate of new energy, so as to realize the efficient development and utilization of wind power and photovoltaic in Gansu new energy base.
