电力交易96点转24点

Convert 电力交易/电网边界条件 96点数据 into 24点小时数据 by averaging each consecutive 4 quarter-hour rows. Use when the user asks to do 96转24、96点转24点、15分钟转小时、日前96点边界条件汇总、检查96点模板公式、修复24点表引用列，尤其是 Excel/xlsx 场景。

Power Trading 96 To 24

Convert 96-point electricity-trading data to 24-point hourly data with the fixed rule: every 4 consecutive 15-minute points become 1 hourly point by arithmetic mean.

Workflow

1. Identify the 96-point source sheet.
2. Confirm there are 96 non-empty data rows.
3. Build the 24-point result by averaging rows 1-4, 5-8, ..., 93-96 for each metric column.
4. If writing into a template, ensure each 24-point metric column references the matching 96-point source column.
5. Verify at least the first 3 hours manually.

Column Mapping Rule

Typical columns:

• 时刻
• 统调负荷
• 省间联络线
• 总出力
• 非现货机组出力
• 新能源
• 水电
• 抽蓄

For hour n in the 24-point table, average source rows ((n-1)*4+1) to (n*4).

Example:

• 24点第1小时 ← 96点第1~4行平均
• 24点第2小时 ← 96点第5~8行平均
• 24点第24小时 ← 96点第93~96行平均

Formula Pattern

When the source sheet is named source96, use this pattern in the 24-point formula sheet:

excel

=SUM(OFFSET(source96!$B$2,(ROW()-2)*4,0,4,1))/4

Change the column letter only. Do not change the matching logic.

Critical Checks

• Keep same-column mapping. 水电 must reference the 96-point 水电 column, not another metric.
• Do not call a column "correct" only because the formula shape looks valid; verify the referenced source column.
• If a 24-point column seems missing, check whether its width was shrunk to near zero instead of being deleted.
• Formula sheets may look blank in readers that do not recalc Excel caches. Check the numeric result sheet for actual values.

Quick Commands

Create a new workbook with source96, result24, and formula24:

bash

python scripts/convert_96_to_24.py input.xlsx output.xlsx

Specify the source sheet explicitly when auto-detection is ambiguous:

bash

python scripts/convert_96_to_24.py input.xlsx output.xlsx --source-sheet "日前96点边界条件数据"

Template Fix Guidance

If the user asks to repair an existing template:

• Edit the existing file minimally.
• Change only the wrong <f> formula nodes or the target column width.
• Preserve the rest of the workbook.
• Re-validate formulas after packing.

A common correct 水电 formula is:

excel

=SUM(OFFSET(日前96点边界条件数据!$H$2,(ROW()-2)*4,0,4,1))/4

Output Expectation

Prefer delivering:

1. A source 96-point sheet
2. A computed 24-point value sheet
3. A formula-based 24-point sheet for auditability

If the user instead wants an existing template updated in place, modify that template rather than creating a separate workbook.
