Weiming Xiong: China Renewable Energy Optimization and Planning Model (REPO) and its Application, PhD thesis, Tsinghua University, 2016

 Background 

• High penetration renewable energy in power sector is the key solution to reach carbon peak before 2030 for China
• Curtailment of renewable power brings great uncertainty to long-term investment
• To achieve high RE penetration in power sector reform

Questions

• Economic potential and its spatial distribution of renewable power ?
• How to model the optimal pathway of renewable energy development ?
• How generation cooperate with transmission to transport renewable energy ?
• How other sectors cooperate with power sector to integrate renewable energy ?
• How to achieve renewable energy with policy instruments ?

REPO（Renewable Electricity Planning and Operations）Model 

• Bottom-up long-term capacity planning and operation model for power and CHP sectors ,least-cost solution for both sectors, generation& transmission capacity investment and operation from 2012 to 2050
• Unit-commitment in long-term capacity model structure
• High-resolution （0.5longitude*0.66 latitude）, provincial transmission matrix
• 57technologiesincludinggeneration,CHP,storage, ….
• Based on Balmorel platform, Relaxed Mixed Integer LP problem in GAMS
