Analysis On Electricity Trading And Price Of Transmission Of Electricity From Yunnan To Guangdong

Transmission of electricity from the western to the eastern region of China SouthernPower Grid is one of the earliest start,the largest scale and the best benefits in power grid.It isan important initiative to implement the country’s Western Development Strategy and solvethe Guangdong、Guangxi、Guizhou and Yunnan provinces（regions）power imbalance inresources distribution and load distribution and achieve resource optimization in east and westconfiguration.Among them, the electricity trading of Transmission of Electricity from Yunnanto Guangdong as one of the most important trading of transmission of electricity from west toeast in southern region in and future Eleventh Five-Year.electricity trading contractcompletion rate，the level of electricity price and transmission price will have a greatinfluence on the power transmission from west to east.In this paper, aiming at the existingfrom Yunnan to Guangdong framework agreement power completion rate fluctuationscharacteristics, analysis of the reasons from the pattern of interests both sending and receiving,the province as the entity of management system,and the price mechanism and so on. Inrecent years with the power transmission from west to east trading parties interests,weproposed can effectively improve several measures of the performance rate of powertransmission from west to east and some suggestions for improving compliance mechanism.To promote sustainable development of power transmission from west to east.The electricityand transmission price of Yunnan to Guangdong UHVDC project according to net-to-netpower transmission price of Yunnan to Guangdong. The current electricity price not fully takeinto account the external costs caused by power development. In fact, the existence of theimbalance in the distribution of benefits, it’s requires the countries to introduce relevantenvironmental and social standards of compensation, in order to realize the coordinateddevelopment of resource development and environmental protection.By calculating the levelof transmission price of Yunnan to Guangdong UHVDC project,we found the problem is thatthe method of approving transmission price by a single line can not be fully applicable to thecurrent situation of the development of SCG. The single electricity price model did not fullyembody the value of the power grid which transmission electric from west to east. On thebasis of the analysis mentioned above, using the two-part tariff or peak and valley price model in thepower transmission from west to east is necessary,and calculating the transmission price of Yunnan toGuangdong UHVDC project by two-part tariff theory. Finally,suggestions for the electricityprice and transmission price of Yunnan to Guangdong should be timely adjusted according tothe principle of cost compensation,to construct a reasonable return price mechanism of power transmission from west to east.
