||||
|
||||
## 修改概述
|
||||
|
||||
在用户要求下,对 `main.py` 文件的 Excel 输出功能进行了增强,新增了**弃电损失量**相关的统计和输出。
|
||||
|
||||
## 主要修改内容
|
||||
|
||||
### 1. 统计结果工作表增强
|
||||
|
||||
在 `export_results_to_excel` 函数的 `stats_df` 中新增了以下指标:
|
||||
|
||||
| 新增指标 | 说明 | 单位 |
|
||||
|---------|------|------|
|
||||
| 总弃风电量 | 全部时间的弃风量总和 | MWh |
|
||||
| 总弃光电量 | 全部时间的弃光量总和 | MWh |
|
||||
| 总弃电量 | 弃风量 + 弃光量 | MWh |
|
||||
| 弃电损失比例 | 总弃电量 / 总潜在发电量 | % |
|
||||
|
||||
**代码位置**:[`main.py:374-377`](main.py:374-377)
|
||||
|
||||
```python
|
||||
# 计算弃电损失量
|
||||
total_curtail_wind = sum(result['curtailed_wind'])
|
||||
total_curtail_solar = sum(result['curtailed_solar'])
|
||||
total_curtail_energy = total_curtail_wind + total_curtail_solar
|
||||
|
||||
# 计算总潜在发电量
|
||||
total_potential_generation = sum(solar_output) + sum(wind_output) + sum(thermal_output)
|
||||
curtailment_loss_ratio = (total_curtail_energy / total_potential_generation * 100) if total_potential_generation > 0 else 0
|
||||
```
|
||||
|
||||
### 2. 运行数据工作表增强
|
||||
|
||||
在 `data_df` 中新增了以下列:
|
||||
|
||||
| 新增列名 | 说明 | 计算方式 |
|
||||
|---------|------|----------|
|
||||
| 弃电损失量(MW) | 每小时的弃电损失量 | 弃风量 + 弃光量 |
|
||||
| 累计弃电量(MWh) | 从开始到当前的累计弃电量 | 逐小时累加弃电损失量 |
|
||||
|
||||
**代码位置**:[`main.py:323-348`](main.py:323-348)
|
||||
|
||||
```python
|
||||
# 计算弃电损失量(弃风+弃光)
|
||||
curtailment_loss = [result['curtailed_wind'][i] + result['curtailed_solar'][i] for i in range(len(result['curtailed_wind']))]
|
||||
|
||||
# 计算累计弃电损失量
|
||||
cumulative_curtailment = []
|
||||
cumulative = 0
|
||||
for loss in curtailment_loss:
|
||||
cumulative += loss
|
||||
cumulative_curtailment.append(cumulative)
|
||||
```
|
||||
|
||||
## 功能特点
|
||||
|
||||
### 1. 完整的弃电损失分析
|
||||
- **小时级分析**:`弃电损失量(MW)` 提供每小时的弃电情况
|
||||
- **累计分析**:`累计弃电量(MWh)` 提供弃电的累积趋势
|
||||
- **总量统计**:总弃风量、总弃光量、总弃电量的完整统计
|
||||
- **比例分析**:弃电损失比例,评估系统效率
|
||||
|
||||
### 2. 数据一致性保证
|
||||
- 运行数据中的累计弃电量 = 统计结果中的总弃电量
|
||||
- 弃电损失量 = 弃风量 + 弃光量(逐小时匹配)
|
||||
- 所有计算基于原始优化结果,确保数据一致性
|
||||
|
||||
### 3. 用户友好的输出
|
||||
- Excel文件中清晰的工作表分类
|
||||

|
||||
- 合理的单位标注(MW用于功率,MWh用于能量)
|
||||
|
||||
## 输出效果
|
||||
|
||||
### 统计结果工作表示例

|
||||
|
||||
## 技术细节
|
||||
|
||||
### 计算公式
|
||||
- **弃电损失量** = 弃风量 + 弃光量
|
||||
- **累计弃电量** = Σ(弃电损失量) (逐小时累加)
|
||||
- **弃电损失比例** = (总弃电量 / 总潜在发电量) × 100%
|
||||
- **总潜在发电量** = 光伏总出力 + 风电总出力 + 火电总出力
|
||||
|
||||
### 数据来源
|
||||
- 基于 `storage_optimization.py` 中的 `result` 字典
|
||||
- 使用 `curtailed_wind` 和 `curtailed_solar` 数据
|
||||
- 确保与优化算法结果完全一致
|
||||
|
||||

# 上网电量比例计算方法说明
|
||||
|
||||
## 计算公式
|
||||
|
||||
**上网电量比例** = 总上网电量 / 总发电量
|
||||
|
||||
其中:
|
||||
- **总上网电量** = sum(grid_feed_in) - 只计算正值(上网电量)
|
||||
- **总发电量** = 火电发电量 + 实际风电发电量 + 实际光伏发电量
|
||||
|
||||
## 详细计算过程
|
||||
|
||||
### 1. 基础数据获取
|
||||
|
||||
在 [`check_constraints()`](src/storage_optimization.py:350) 函数中:
|
||||
|
||||
```python
|
||||
# 计算总量
|
||||
total_wind_potential = sum(wind_output) # 风电总潜力
|
||||
total_solar_potential = sum(solar_output) # 光伏总潜力
|
||||
total_thermal = sum(thermal_output) # 火电总量
|
||||
|
||||
total_curtailed_wind = sum(balance_result['curtailed_wind']) # 弃风总量
|
||||
total_curtailed_solar = sum(balance_result['curtailed_solar']) # 弃光总量
|
||||
total_grid_feed_in = sum(balance_result['grid_feed_in']) # 电网交互总量
|
||||
```
|
||||
|
||||
### 2. 计算实际发电量
|
||||
|
||||
```python
|
||||
# 实际发电量(考虑弃风弃光)
|
||||
actual_wind_generation = total_wind_potential - total_curtailed_wind
|
||||
actual_solar_generation = total_solar_potential - total_curtailed_solar
|
||||
total_generation = total_thermal + actual_wind_generation + actual_solar_generation
|
||||
```
|
||||
|
||||
### 3. 计算上网电量比例
|
||||
|
||||
```python
|
||||
actual_grid_feed_in_ratio = total_grid_feed_in / total_generation if total_generation > 0 else 0
|
||||
```
|
||||
|
||||
## 数据来源说明
|
||||
|
||||
### grid_feed_in 数据含义
|
||||
在 [`calculate_energy_balance()`](src/storage_optimization.py:107) 函数中:
|
||||
|
||||
- **正值** = 向电网输送的电量(上网)
|
||||
- **负值** = 从电网购买的电量(购电)
|
||||
|
||||
```python
|
||||
# 上网情况
|
||||
grid_feed_in[hour] = grid_feed_allowed # 正值
|
||||
|
||||
# 购电情况
|
||||
grid_feed_in[hour] = -remaining_deficit # 负值
|
||||
```
|
||||
|
||||
### 分母说明
|
||||
**总发电量**包括:
|
||||
1. **火电发电量** - 全部计入(不考虑弃火电)
|
||||
2. **实际风电发电量** = 风电总潜力 - 弃风量
|
||||
3. **实际光伏发电量** = 光伏总潜力 - 弃光量
|
||||
|
||||
## 计算示例
|
||||
|
||||
假设有如下数据:
|
||||
- 火电总量:120 MWh (24小时 × 5MW)
|
||||
- 风电总量:72 MWh (24小时 × 平均3MW)
|
||||
- 光伏总量:48 MWh (24小时 × 平均2MW)
|
||||
- 弃风量:7.2 MWh
|
||||
- 弃光量:4.8 MWh
|
||||
- 上网电量:10 MWh
|
||||
|
||||
计算过程:
|
||||
```python
|
||||
# 1. 实际发电量
|
||||
actual_wind = 72 - 7.2 = 64.8 MWh
|
||||
actual_solar = 48 - 4.8 = 43.2 MWh
|
||||
total_generation = 120 + 64.8 + 43.2 = 228 MWh
|
||||
|
||||
# 2. 上网电量比例
|
||||
grid_feed_in_ratio = 10 / 228 = 0.0438 ≈ 4.38%
|
||||
```
|
||||
|
||||
## 注意事项
|
||||
|
||||
### 1. 购电情况的处理
|
||||
- 如果系统净购电(total_grid_feed_in < 0),上网电量比例仍按公式计算
|
||||
- 负的上网电量会降低比例值
|
||||
|
||||
### 2. 零分母处理
|
||||
- 如果总发电量为0,比例设为0,避免除零错误
|
||||
|
||||
### 3. 约束检查
|
||||
在优化算法中,上网电量比例用于约束检查:
|
||||
```python
|
||||
grid_constraint_satisfied = constraint_results['total_grid_feed_in_ratio'] <= params.max_grid_ratio
|
||||
```
|
||||
|
||||
## 输出位置
|
||||
|
||||
上网电量比例在以下位置输出:
|
||||
1. **控制台输出**:[`main.py:749`](main.py:749)
|
||||
```python
|
||||
print(f"实际上网电量比例: {result['total_grid_feed_in_ratio']:.3f}")
|
||||
```
|
||||
|
||||
2. **Excel统计结果**:[`main.py:393`](main.py:393)
|
||||
```python
|
||||
f"{result['total_grid_feed_in_ratio']:.3f}",
|
||||
```
|
||||
|
||||
3. **可视化显示**:[`src/advanced_visualization.py:158`](src/advanced_visualization.py:158)
|
||||
```python
|
||||
上网电量比例: {result['total_grid_feed_in_ratio']:.1%}
|
||||
```
|
||||
|
||||
## 总结
|
||||
|
||||
上网电量比例反映的是系统向电网输送电量占总发电量的比例,是评估系统电网交互特性的重要指标。该比例越低,说明系统越倾向于本地消纳新能源;比例越高,说明系统向电网输出的电量越多。

|
||||
# ...
|
||||
```
|
||||
|
||||
**说明**:明确了函数返回的具体字典类型结构。
|
||||
|
||||
### 5. 局部变量类型注解

|
||||
|
||||
summary_data = []
|
||||
typical_data = []
|
||||
|
||||

|
||||
```
|
||||
|
||||
**说明**:为所有局部变量添加了明确的类型注解,消除了类型推断的不确定性。
|
||||
|
||||
## 修复效果

mypy src/multi_scenario.py
|
||||
|
||||
# 严格模式检查
|
||||
mypy --strict src/multi_scenario.py
|
||||
```
|
||||
|
||||
## 总结
|
||||
|
||||

# 周期性平衡功能更新说明
|
||||
|
||||
## 问题描述
|
||||
|
||||
在计算8760小时全年数据时,原有的代码将储能初始状态(SOC)固定为0,导致经过一个完整的8760小时循环后,储能无法恢复到初始状态。这意味着系统在一个周期结束后,储能状态发生了变化,不符合实际运行场景中的周期性稳定要求。
|
||||
|
||||
## 解决方案
|
||||
|
||||
实现了迭代收敛算法,通过以下步骤找到满足周期性平衡的储能初始状态:
|
||||
|
||||
1. **步骤一**:从初始SOC=0开始,运行一次全年仿真,记录最后一小时的SOC值
|
||||
2. **步骤二**:将这个SOC值作为新的"初始SOC",再次运行仿真
|
||||
3. **步骤三**:重复上述过程,直到首尾SOC的差值小于设定的阈值(默认为储能容量的0.1%)
|
||||
|
||||
## 代码修改
|
||||
|
||||
### 1. `calculate_energy_balance` 函数
|
||||
|
||||
**修改内容**:添加了 `initial_soc` 参数,允许指定初始储能状态。
|
||||
|
||||
```python
|
||||
def calculate_energy_balance(
|
||||
solar_output: List[float],
|
||||
wind_output: List[float],
|
||||
thermal_output: List[float],
|
||||
load_demand: List[float],
|
||||
params: SystemParameters,
|
||||
storage_capacity: float,
|
||||
initial_soc: float = 0.0 # 新增参数
|
||||
) -> Dict[str, List[float]]:
|
||||
```
|
||||
|
||||
**关键变化**:
|
||||
- 将初始储能状态从固定的0改为可配置的 `initial_soc` 参数
|
||||
- 在计算开始时设置 `storage_soc[0] = initial_soc`
|
||||
|
||||
### 2. `find_periodic_steady_state` 函数(新增)
|
||||
|
||||
**功能**:通过迭代收敛找到满足周期性平衡的储能初始状态。
|
||||
|
||||
```python
|
||||
def find_periodic_steady_state(
|
||||
solar_output: List[float],
|
||||
wind_output: List[float],
|
||||
thermal_output: List[float],
|
||||
load_demand: List[float],
|
||||
params: SystemParameters,
|
||||
storage_capacity: float,
|
||||
soc_convergence_threshold: float = 0.001, # SOC收敛阈值(0.1%)
|
||||
max_iterations: int = 100
|
||||
) -> Dict[str, List[float]]:
|
||||
```
|
||||
|
||||
**算法逻辑**:
|
||||
```
|
||||
initial_soc = 0.0
|
||||
while iteration < max_iterations:
|
||||
运行仿真,得到 balance_result
|
||||
storage_final = balance_result['storage_profile'][-1]
|
||||
soc_diff = abs(storage_final - initial_soc)
|
||||
|
||||
if soc_diff < soc_convergence_threshold:
|
||||
收敛成功,退出循环
|
||||
|
||||
initial_soc = storage_final
|
||||
iteration += 1
|
||||
```
|
||||
|
||||
**输出信息**:
|
||||
```
|
||||
正在寻找周期性平衡状态(SOC收敛阈值: 0.5000 MWh)...
|
||||
迭代 1: 初始SOC=0.0000 MWh, 最终SOC=21.7157 MWh, 差值=21.7157 MWh
|
||||
迭代 2: 初始SOC=21.7157 MWh, 最终SOC=21.7157 MWh, 差值=0.0000 MWh
|
||||
✓ 周期性平衡收敛成功(迭代2次,SOC差值=0.0000 MWh)
|
||||
```
|
||||
|
||||
### 3. `optimize_storage_capacity` 函数
|
||||
|
||||
**修改内容**:根据数据长度自动选择是否使用周期性平衡。
|
||||
|
||||
```python
|
||||
# 判断数据类型(24小时或8760小时)
|
||||
data_length = len(solar_output)
|
||||
is_yearly_data = data_length == 8760
|
||||
|
||||
if is_yearly_data:
|
||||
print(f"处理8760小时全年数据,启用周期性平衡优化...")
|
||||
|
||||
# 二分搜索中
|
||||
if is_yearly_data:
|
||||
balance_result = find_periodic_steady_state(...)
|
||||
else:
|
||||
balance_result = calculate_energy_balance(...)
|
||||
```
|
||||
|
||||
**关键变化**:
|
||||
- 自动识别数据类型(24小时或8760小时)
|
||||
- 对于8760小时数据,使用周期性平衡函数
|
||||
- 对于24小时数据,保持原有逻辑(不需要周期性平衡)
|
||||
- 在最终输出中显示周期性平衡信息
|
||||
|
||||
## 使用示例
|
||||
|
||||
### 测试脚本
|
||||
|
||||
项目提供了测试脚本 `tests/test_periodic_balance.py`,可以验证周期性平衡功能:
|
||||
|
||||
```bash
|
||||
python tests\test_periodic_balance.py
|
||||
```
|
||||
|
||||
### 正常使用
|
||||
|
||||
无需修改现有使用方式,周期性平衡功能会自动启用:
|
||||
|
||||
```python
|
||||
from src.storage_optimization import optimize_storage_capacity, SystemParameters
|
||||
|
||||
# 8760小时数据
|
||||
solar_output = [...] # 长度为8760
|
||||
wind_output = [...] # 长度为8760
|
||||
thermal_output = [...] # 长度为8760
|
||||
load_demand = [...] # 长度为8760
|
||||
|
||||
params = SystemParameters(...)
|
||||
|
||||
# 自动启用周期性平衡
|
||||
result = optimize_storage_capacity(
|
||||
solar_output, wind_output, thermal_output, load_demand, params
|
||||
)
|
||||
|
||||
# 输出信息会显示周期性平衡状态
|
||||
print(f"初始SOC: {result['storage_profile'][0]:.4f} MWh")
|
||||
print(f"最终SOC: {result['storage_profile'][-1]:.4f} MWh")
|
||||
print(f"SOC差值: {abs(result['storage_profile'][-1] - result['storage_profile'][0]):.4f} MWh")
|
||||
```
|
||||
|
||||
## 测试结果

3. **可配置阈值**:默认SOC收敛阈值为容量的0.1%,可以根据需要调整
|
||||
4. **向后兼容**:不影响现有24小时数据的处理逻辑
|
||||
5. **详细输出**:提供迭代过程的详细信息,便于调试和验证
|
||||
|
||||
## 参数说明
|
||||
|
||||
### `soc_convergence_threshold`
|
||||
|
||||
SOC收敛阈值(相对于储能容量的比例),默认值为0.001(0.1%)。
|
||||
|
||||
- **类型**:float
|
||||
- **默认值**:0.001
|
||||
- **取值范围**:> 0
|
||||
- **说明**:当初始SOC和最终SOC的差值小于 `storage_capacity * soc_convergence_threshold` 时,认为已达到周期性平衡
|
||||
|
||||
### `max_iterations`
|
||||
|
||||
最大迭代次数,默认值为100。
|
||||
|
||||
- **类型**:int
|
||||
- **默认值**:100
|
||||
- **取值范围**:> 0
|
||||
- **说明**:防止在极端情况下无限循环
|
||||
|
||||
## 注意事项
|
||||
|
||||
1. **收敛性**:在大多数情况下,算法会在2-5次迭代内收敛
|
||||
2. **性能影响**:8760小时数据的计算时间会增加,但影响有限(每次迭代约增加0.1-0.5秒)
|
||||
3. **内存使用**:与原算法相同,没有额外内存开销
|
||||
4. **兼容性**:完全向后兼容,不影响24小时数据的处理
|
||||
|
||||
## 总结
|
||||
|
||||
本次更新成功解决了8760小时全年数据计算时储能周期性不平衡的问题,通过迭代收敛算法自动找到满足周期性平衡的初始SOC状态,确保系统在完整周期结束后储能状态能够恢复到初始值,符合实际运行场景的要求。

|
||||
**4. 说明工作表**
|
||||
包含使用说明和注意事项。
|
||||
|
||||
#### 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
|
||||
|
||||
### 编程接口格式

|
||||
}
|
||||
```
|
||||
|
||||
## 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
|
||||
