Abstract:According to the future power development status in Sichuan province including electric power demand,power installed capacity and grid planning etc.,the reasonable construction scale for new energy planning of Sichuan province in 2020 are studied and analyzed.On one hand,the power construction market space of new energy in Sichuan is calculated and analyzed based on power and electricity quantity balance of Sichuan power grid,as well as the influence of new energy construction on the quantity of abandoning energy in high flow period and the thermal power utilization hours. On the other hand,the influence of grid construction and power transmission capability on new energy construction scale of Sichuan are analyzed according to Sichuan grid construction planning.
