Abstract: In recent years, the global levelized cost of energy (LCOE) of wind and PV power generation has been decreasing, which improves the economy of renewable energy power generation and provides effective support for alleviating the subsidy dilemma. The development of renewable energy has entered the "post-subsidy era". The paper analyzes the prospect of renewable energy development in China in the mid-and long-term according to the national energy transformation development goals, studies the variation tendency of renewable energy generation cost, and puts forward the key issues that should be paid attention to in the "post-subsidy era". The key measures are analyzed to improve the renewable energy carrying-capacity of power system. In the end, related suggestions are proposed to guarantee the scientific and healthy development of renewable energy.

Key words: renewable energy, post-subsidy period, the mid-and long-term, carrying-capacity of power system, power planning
