In order to promote the healthy development of inter-provincial medium- and long-term centralized transaction market and respond to the policy on inter-provincial and inter-regional transaction price limitation,an inter-provincial medium- and long-term centralized transaction clearing model is proposed based on sequential optimization. The model determines two different upper-level objective functions according to whether or not the average electricity price of medium- and long-term clearing in the lower level meets the price limitation constraint,which provides guidance for selecting the optimal transaction scheme in inter-provincial market. An inter-provincial medium- and long-term centralized transaction scheme reduction method is proposed under price limitation in clearing stage,which reduces the electricity price limitation through iterative reduction mode while considering the economy. Based on the data of actual power grid,the effectiveness of the proposed model is verified by simulation analysis.
