丽水市充电站价格浮动综合分析数据
收藏资源简介：
通过监测充电站价格数据和充电桩实时空闲状态，结合绿色能源供给数据，为车主、运营方、政府提供三层服务： 车主：按 “价格最优、速度最快、绿电优先” 智能推荐充电站，支持即充、预约、错峰充电，兼顾省钱与低碳； 运营方：实时分析价格浮动、桩位占用等数据，动态调整电价和设备运维策略，提升充电桩利用率； 政府：汇总区域充电价格、负荷分布、绿电消纳等数据，辅助政策制定和双碳目标追踪。1、数据采集：从数据库中提取充电站关于充电收费最高价与最低价及充电桩空闲情况：2、处理数据：将每日的最低价与最高价分别进行累加，进而得到A（最低价总和）与B（最高价总和），进一步通过公式（A+B）/2/365得出的C（均价），进一步提取充电站中最高价的峰值与最低价的谷值，该峰值与谷值分别作为该数据的年最高价与年最低价，进一步将(年最高价与充电站电价的差的绝对值）/充电站电价*100%，从而得出+浮动值，进一步将(年最低价与充电站电价的差的绝对值）/充电站电价*100%，从而得出-浮动值，进一步根据得出的+浮动值与-浮动值确定均价的浮动区间（-浮动值~+浮动值）。
By monitoring charging station price data, real-time idle status of charging piles and combining with green energy supply data, this dataset provides three-tier services for vehicle owners, charging station operators and government agencies: - For vehicle owners: Intelligently recommend charging stations based on the principles of "optimal price, fastest charging speed and priority for green electricity", support on-site charging, reservation and off-peak charging to balance cost savings and low-carbon objectives; - For charging station operators: Conduct real-time analysis on data such as price fluctuations and pile occupancy, dynamically adjust electricity pricing and equipment operation and maintenance strategies to improve the utilization rate of charging piles; - For government agencies: Aggregate regional charging price data, load distribution and green power accommodation data to assist policy formulation and tracking of dual-carbon targets. ### Data Collection Extract the maximum and minimum charging fees as well as the real-time idle status of charging piles from the database. ### Data Processing 1. Accumulate the daily minimum and maximum charging fees separately to obtain the total minimum price (A) and total maximum price (B). Further calculate the average annual price (C) using the formula (A+B)/2/365. 2. Extract the peak value of daily maximum prices and the trough value of daily minimum prices of charging stations, which serve as the annual maximum price and annual minimum price of the dataset respectively. 3. Calculate the positive fluctuation value as |annual maximum price - charging station's charging price| / charging station's charging price * 100%, and the negative fluctuation value as |annual minimum price - charging station's charging price| / charging station's charging price * 100%. 4. Determine the fluctuation interval of the average price as (-negative fluctuation value ~ +positive fluctuation value) based on the calculated positive and negative fluctuation values.
