Abstract: In the context of building new power systems, the time-series production simulation powered by digital transformation has become an important tool for the operation evaluation and planning decision of new power systems. This paper summarizes the domestic and foreign research results on time-series production simulation, and the applications and solving techniques of timeseries production simulation in new power systems. First, the structure and characteristics of time-series production simulation are introduced, and the application scenarios of time-series production simulation are reviewed from the aspects of power quantity balance calculation, quantitative analysis of “carbon emission peak and carbon neutrality” measures, and future power grid form and evolution path. Then, the existing solving techniques of time-series production simulation are classified according to their characteristics, and the limitations of different solving techniques are discussed. Finally, the research of time-series production simulation of new power systems is prospected.
