Abstract: Abstract The orderly synergy of the four sub-systems of renewable energy that is, supply, transmission, demand, and energy storage is key to restricting its efficient development and utilization. Our study develops a measurement model to synergize the "supply-transmission-demand-storage" system. Additionally, to maximize the synergy level of the entire system and minimize the total cost, it proposes a multi-objective optimization model, improving the synergy level of China’s renewable energy sub-systems. The results show that: (1) The integrated measurement and multi-objective optimization models can solve the problems of the synergy among "supply-transmission-demand-storage" and improve optimization. (2) From 2009 to 2020, only 8.33% of the years in the system were at a good synergy level. However, after optimization, the average synergy level in 2021–2040 can increase by 10.31% and 10.56%, respectively, compared with historical years and business-as-usual scenarios. (3) In 2030, nuclear and renewable power will replace coal-fired power, becoming the primary source for China's electricity consumption. In 2040, the proportion of renewable energy power generation will reach 51.51%. (4) From 2021 to 2040, the growth rate of the average annual energy storage installed capacity will be high at 15.82%, while that of inter-provincial transmission power will slow down to only 2.15%.
