Research on Capacity Configuration of Wind/Solar/Thermal Power and Energy Storage Complementary for UHVDC Transmission System

This paper studies the capacity configuration of wind/solar/thermal power and energy storage complementary for UHVDC transmission system using time-series production simulation method. The influence of several aspects, such as operation mode, thermal power capacity, renewable energy capacity and wind/solar proportion, power curve of the transmission system, energy storage capacity and time length, on the percentage of renewable energy generation capacity, the utilization hour of UHVDC transmission system and the utilization rate of renewable energy are analyzed. Finally, several suggestions of the capacity configuration on wind/solar/thermal power sources and energy storage complementary are put forward.
