This article briefly introduces the traditional allocation method of park level distribution measurement and peak shaving resources based on the typical day method

and analyzes the technical defects of the traditional method.The data processing process is presented from three aspects: wind power data

photovoltaic data

and newly added load data. A calculation model for optimizing peak shaving resource allocation on the distribution side at the park level

considering the variance of new energy consumption and peak shaving resource output

is proposed. The calculation model includes two parts: optimization objective function and constraint conditions. The constraint conditions mainly include renewable energy output constraints

peak shaving resource output constraints

energy storage state of charge constraints

network constraints

and other factors.The overall process of the main indicators and allocation methods used for peak shaving resource allocation calculation is discussed

and the applicability and effectiveness of the proposed method are verified through numerical examples.
