Abstract
The international community pays much attention lately to issues such as environment protecting and climate change. It actively promotes energy transformation and complementation globally. In order to realize the transformation of low-carbon energy, it is necessary to effectively utilize Renewable Energy (RE) and optimize the energy layout. In this context, the development of the RE industry and related operational decisions have become hot topics. The purpose of this paper is to summarize the research on the supply and demand relationship of RE multi-energy complementary systems. First, the descriptive results and bibliometric analysis of published papers from 1998 to 2019 are introduced to show the current developments in this field. Then, the existing research is divided into four categories including supply or demand research, system coordination, decision equilibrium relationship and decision environment. And these topics are systematically reviewed and analyzed. Finally, the development directions of future research are discussed from the perspective of research problems, methods and decision environment.
