Review compares three smart-grid wind-solar-storage schemes

What the study found: The article compares three wind-solar-storage optimization schemes used in smart grids: Hainan Multi Energy Complementary Island Microgrid, Zhangbei Demonstration Project, and Xiong'an Urban Computing Center. It identifies their principles, characteristics, achieved effects, and advantages.

Why the authors say this matters: The authors conclude that optimizing the mix of wind, solar, and energy storage can help address the intermittency and instability of renewable power in smart grids. They also suggest these schemes provide directions and a theoretical basis for future smart-grid optimization.

What the researchers tested: The article is based on the principle of hybrid operation of wind, solar, and energy storage in smart grids. It focuses on three widely used optimization strategies: multi-energy complementarity, source-grid-load-storage, and multi-grid integration and interconnection.

What worked and what didn't: The abstract does not report new experimental results or direct performance measurements. It states that the three example schemes were analyzed for their principles, characteristics, achieved effects, and advantages, but it does not specify detailed comparative outcomes.

What to keep in mind: The available summary does not provide quantitative data, limitations, or a detailed method description. The paper also presents hypotheses and prospects for future smart-grid optimization, but those are not described in detail here.
