The rapid development and utilization of renewable energy generations (REGs), such as wind power and photovoltaic power, is an important measure for modern power system to achieve carbon neutrality and solve global energy crisis. However, the randomness and volatility of renewable energy generations lead to serious reliability concerns and financial risks to different decision-makers, and the large-scale integration of power electronic brings huge challenges to the planning, operation and control optimization of renewable energy-based systems. Therefore, to achieve the integration of large-scale renewable energy generations, advanced planning, operation and control optimization methods and strategies for modern power systems are required to be developed based on the state-of-the-art power system technologies. The aim of this Research Topic is to report the latest advancements in planning, operation and control optimization of large-scale renewable energy generations in modern power system to solve potential difficulties and challenges.

With the general acknowledgement that climate change constitutes an existential threat to both mankind and to the planet, the quest for more sustainable and environmentally-friendly ways of developing and maintaining human civilizations has become ever more important in recent years. This book presents the proceedings of GEESD2022, the 3rd International Conference on Green Energy, Environment and Sustainable Development. Due to continuing travel restrictions as a result of the COVID-19 pandemic, the conference was held as a hybrid event, part face-to-face in Beijing, China, and partly online via Zoom, on 29 June 2022. The 141 papers included here were selected after a rigorous 6-month process of evaluation and peer-review from the more than 300 submissions received, and are grouped into 7 sections: energy system and smart control; sustainable and green energy; environmental modeling and simulation; environmental science and pollution research; ecology and rural environment; building and environment; and water and mineral resources. The book provides an overview of the most up-to-date findings and technologies current in green energy, environment and sustainable development today, and will be of interest to all those working in the field.
