In recent years

the renewable energy in China has developed rapidly

at the same time

the phenomena of wind and solar power curtailment has also become an increasingly serious problem. To solve the problem

the country has introduced the policy of renewable portfolio standards. Firstly

the influence of the policy

focusing on the capacity growth effect

grid connection effect and restriction effect

is analyzed. From the aspects of tapping the local energy potential

accepting the transmission of electricity across regions

and optimizing the transmission curve outside the area

the corresponding new energy consumption strategies are proposed. Finally

based on the sequential production simulation model

the renewable energy accommodation in a province in 2020 under different kinds of strategies is empirically analyzed.
