Abstract: Tianshan-Zhongzhou UHVDC Project is the first UHVDC project in Xinjiang for outbound power transmission. With a designed annual transmission capacity of 44 billion kW·h, it will play an important role in energy resources optimization for a large area. The Tianshan-Zhongzhou UHVDC Transmission Project is built for transmission of both thermal and wind power in Xinjiang. Different proportion of the thermal and wind power has different influences on the operation of Henan power grid. The magnitude of power transmission during Xinjiang power valley will influence the load peaking operation and increase the peaking cost of Henan power grid. By taking this project as an example, a study is made on estimation of receiving-end grid power peaking cost and compensation mechanism based on large-proportion renewable energy transmission, which is expected to provide a reference for formulating relevant electricity price policy.

Key words: Tianshan-Zhongzhou UHVDC Project, themal power mixed with wind power transmission, peaking cost, electric power price;new energy
