+
+Excel文件必须包含以下列（列名必须完全一致）：
+
+| 列名 | 说明 | 单位 | 要求 |
+|------|------|------|------|
+| 光伏出力(MW) | 光伏发电功率曲线 | MW | 非负数 |

+
+#### 数据行数要求
+
+- **8760小时数据**：必须包含8760行数据（全年每小时一个数据点）
+- **24小时数据**：必须包含24行数据（典型日每小时一个数据点）
+
+#### 创建Excel模板
+
+程序提供自动创建Excel模板的功能：
+
+```bash
+# 创建8760小时模板
+python main.py --create-template 8760
+
+# 创建24小时模板
+python main.py --create-template 24
+```
+
+#### 使用Excel数据
+
+**命令格式：**
+```bash
+python main.py --excel <Excel文件路径>
+```
+
+**示例：**
+```bash
+python main.py --excel my_data.xlsx
+python main.py --excel data_template_8760.xlsx
+```
+
+#### Excel文件示例
+
+**8760小时数据示例：**
+
+| 小时 | 光伏出力(MW) | 风电出力(MW) | 火电出力(MW) | 负荷需求(MW) |
+|------|-------------|-------------|-------------|-------------|
+| 1    | 0.0         | 2.1         | 5.0         | 3.2         |
+| 2    | 0.0         | 2.3         | 5.0         | 2.8         |
+| ...  | ...         | ...         | ...         | ...         |
+| 8760 | 0.0         | 2.0         | 5.0         | 3.5         |
+
+**24小时数据示例：**
+
+| 小时 | 光伏出力(MW) | 风电出力(MW) | 火电出力(MW) | 负荷需求(MW) |
+|------|-------------|-------------|-------------|-------------|
+| 1    | 0.0         | 2.0         | 5.0         | 3.0         |
+| 2    | 0.0         | 3.0         | 5.0         | 4.0         |
+| ...  | ...         | ...         | ...         | ...         |
+| 24   | 0.0         | 2.0         | 5.0         | 2.0         |
+
+#### 数据处理逻辑
+
+**24小时数据扩展：**
+当提供24小时数据时，程序会自动将其扩展到8760小时：
+- 将24小时模式重复365次
+- 模拟全年数据，便于进行长期储能优化
+
+**数据验证：**
+程序会自动验证：
+- 文件是否存在
+- 数据行数是否正确
+- 必需列是否存在
+- 数据类型是否为数值
+- 是否包含负值
+
+**错误处理：**
+如果数据格式不正确，程序会显示详细的错误信息：
+```
+错误：数据行数应为8760，实际为1000
+错误：缺少必需的列：['光伏出力(MW)']
+错误：列'光伏出力(MW)'包含负值
+```
+
+#### 注意事项
+
+1. **文件格式**：仅支持.xlsx格式（Excel 2007及以上）
+2. **编码**：建议使用UTF-8编码保存Excel文件
+3. **数据精度**：保留小数点后2位即可
+4. **文件大小**：8760小时数据文件通常小于1MB
+5. **内存要求**：处理8760小时数据需要约100-200MB额外内存
+
+#### 故障排除
+
+**常见问题：**
+
+1. **"文件不存在"错误**
+   - 检查文件路径是否正确
+   - 确保文件没有被其他程序占用
+
+2. **"缺少必需的列"错误**
+   - 检查列名是否完全匹配（包括括号和单位）
+   - 确保没有多余的空格
+
+3. **"数据类型错误"**
+   - 确保所有数据列都是数值格式
+   - 检查是否有文本格式混入
+
+4. **"包含负值"错误**
+   - 所有功率数据必须为非负数
+   - 检查数据源是否有异常值
+
+**性能优化建议：**
+
+1. **大文件处理**：对于8760小时数据，确保系统有足够内存
+2. **数据预处理**：在Excel中预先清理和验证数据
+3. **批量处理**：可以编写脚本批量处理多个Excel文件

+    'max_storage_limit': float            # 储能容量上限设置值
+}
+```
+
+## 算法原理
+
+### 电能平衡原则
+程序遵循电能平衡原则：
+```
+总发电量 + 储能放电/效率 = 总负荷 + 储能充电×效率 + 弃风弃光 + 上网电量
+```
+
+### 优化算法
+采用二分搜索算法寻找满足所有约束的最小储能容量：
+1. 设置搜索边界（0到最大可能容量或用户设定的上限）
+2. 迭代测试中间容量
+3. 验证所有约束条件
+4. 调整搜索范围直到收敛
+
+### 储能容量上限处理
+当设置了`max_storage_capacity`参数时：
+1. 搜索范围上限被限制为设定值
+2. 如果在容量限制内无法找到满足所有约束的解，程序会：
+   - 输出警告信息
+   - 使用最大允许容量计算结果
+   - 返回`capacity_limit_reached=True`标记
+   - 某些约束条件可能无法满足
+
+### 购电功能处理
+当设置`max_grid_ratio`为负值时：
+1. 系统允许从电网购电，负值表示最大购电比例
+2. 约束条件调整为：实际购电比例 ≥ 设定的购电比例
+3. 在结果中，负的上网电量表示购电量
+4. 适用于负荷高峰期本地发电不足的场景
+
+### 约束条件处理
+1. **弃风弃光约束**：控制可再生能源弃用比例
+2. **上网电量约束**：限制向电网输送电量比例
+3. **储能运行约束**：考虑容量、效率和功率限制
+4. **周期平衡约束**：确保储能状态恢复到初始值
