Wind power and photovoltaic power: How to improve the accommodation capability of renewable electricity generation in China?

China's wind curtailment and photovoltaic curtailment was one of the prominent issues in 2014, and the renewable curtailment worsened in 2015. With the rapid growth of renewables, the phenomenon of the insufficiency in renewable accommodation capability is becoming more and more serious in 2016. In that case, the problem of the insufficient accommodation capability is pointed out by analyzing China's development requirements. The renewable power generation scale, the renewable power consumption, and the restrictions on the renewable electricity generation are discussed from the China's market perspective. Meanwhile, the legal environment, the planning requirement, the institutional setting, and the policy tools are introduced from the perspective of governmental regulation. An empirical analysis, a cause analysis and a trend analysis are illustrated before explaining the problem of renewable curtailment and proposing a solution for enhancing the accommodation capability. According to the analysis results, the solution for addressing the wind curtailment and PV curtailment is offered with respect to the technology, the institution, the legislation, and the political aspect. Through the research, the research conclusions are drew finally and the corresponding policy recommendations are put forward.
