Abstract: In order to promote green energy transformation and strive to build a development guideline of clean,low-carbon,safe and efficient energy system,new energy storage planning and layout study is carried out based on power development and peak regulating demand forecast of “14th Five-year Plan" in Shanxi Province according to the actual demand of Shanxi power system,combined with energy storage capacity demand analysis and grid-side energy storage layout ideas.The 24-hour consumption curve on a typical day in April 2021 is taken as an example,the impact of new energy storage access on Shanxi power grid is analyzed in terms of the abandonment rate of new energy and the proportion of new energy generation and so on.At the same time,the medium and long term development goals and key tasks of new energy storage are prospected.And it is expected that energy storage will really play a positive and effective role in the construction of the new power system in the future to ensure the safe and stable operation of the power grid.
