Dr. Sheng’an Zheng is the Director Gen- eral of China Renewable Energy Engineering Institute (CREEI). He graduated from Hohai University in 1983 and was majored in Hy- draulic Structure Mechanics. He was conferred Doctoral Degree in Technology, Economy and Management by Hohai University in 2006. He is also a professor-level senior engineer with special allowance of the State Council.

He worked as the President of Chengdu Design and Engineering Corporation Limited from 2001 to 2011 and the Assistant President and the President of the Survey and Design Division of Power Construction Corporation of China (PowerChina) from 2011 to 2014. From 2014 till now, he has been working in CREEI as the Director General.

President Sheng’an Zheng is a hydropower expert with high prestige in China. He is dedi- cated to the fields of hydropower engineering design and scientific research and management. He has made remarkable scientific achieve- ments in the field of hydropower design. He led and completed the engineering design and key problem resolution of a number of large- and medium-sized hydropower stations, such as Xiluodu Hydropower Station on Jinsha River, Dadu River Pubugou Hydropower Station, and Jinping-I Hydropower Station.



Overview of hydro–wind–solar power complementation development in China

中国水风光多能互补发展综述


Introduction

Hydropower generation in China started over a century ago, greatly contributing to their economic and social development. Wind power and photovoltaic (PV) power generation began on a large scale in the 21st century, and both developed rapidly. The continuous development of economy and society as well as the improvement of people’s living standards lead to growing demand for energy. To reduce air pollution and greenhouse gas (GHG) emission and to realize the goals of the percentage of non- fossil energy as primary energy consumption being 15% and 20% in 2020 and 2030, respectively, China proposed the strategy of vigorous development of renewable energy that makes use of renewable energy such as hydro energy, wind energy, solar energy, among others, in order to guarantee energy security, improve energy configuration and promote the construction of an ecological civilization.

The output of wind and PV power is featured with volatility, intermittence, and randomness with no self- regulating ability, and the swelling grid-connected scale of wind and solar power requires compensatory regulation. With flexible and controllable power sources in the power system, both hydropower and pumped-storage power stations have good regulating ability and energy storage capacity. The mutual complementation of such power stations and wind and solar power under a coordinated operation mode of hydro–wind–solar power can protect the safe grid connection of new energy on a large scale.
