## 🎯 วัตถุประสงค์
|
| 21 |
+
|
| 22 |
+
ระบบนี้ช่วย**หาจำนวน MW ที่สามารถปล่อยเพิ่มได้อย่างปลอดภัย** โดยวิเคราะห์:
|
| 23 |
+
- ✅ **Capacity จริง vs 80% ทฤษฏี** (theoretical safety level)
|
| 24 |
+
- ✅ **Thermal margin** (อุณหภูมิปัจจุบัน vs limit 30°C)
|
| 25 |
+
- ✅ **Electrical parameters** (TEPR/STRR cable health)
|
| 26 |
+
- ✅ **Load forecast** (7-30 วันข้างหน้า)

| Sheet | ข้อมูล | จำนวน | ใช้เพื่อ |
|
| 33 |
+
|-------|--------|------|---------|
|
| 34 |
+
| **samui_load** | โหลดไฟฟ้า (ทุก 15 นาที) | 105,957 | Target: โหลดจริง (MW) |
|
| 35 |
+
| **MAX_TEMP_BY_DAY** | อุณหภูมิน้ำทะเล (รายวัน) | 699 | Feature: Temp regression |
|
| 36 |
+
| **MEASUREMENT_TEPR** | Temperature/Power ตาม distance | 3,199 | Feature: Cable health indicator |
|
| 37 |
+
| **MEASUREMENT_STRR** | Strain/Stress ตาม distance | 2,999 | Feature: Mechanical stability |
|
| 38 |
+
|
| 39 |
+
**ข้อสำคัญ**: TEPR/STRR ❌ ไม่ใช่ load data! ใช้เป็น**features ผ่าน statistics เท่านั้น** (mean, std, min, max)

## ⚠️ ข้อควรรู้
|
| 215 |
+
|
| 216 |
+
### ข้อสำคัญ
|
| 217 |
+
1. **80% Theoretical** = Safety margin ตามข้อกำหนด spec
|
| 218 |
+
2. **Real Capacity** = คำนวณจาก temp + electrical parameters
|
| 219 |
+
3. **Thermal Limit** = Fiber temperature 30°C (constant)
|
| 220 |
+
4. **TEPR/STRR** = Cable health indicators (ใช้เป็น features ผ่าน statistics)
|
| 221 |
+
|
| 222 |
+
### ข้อจำกัด
|
| 223 |
+
- Model accuracy ≈ data quality + ประวัติศาสตร์
|
| 224 |
+
- Forecast accuracy ↓ สำหรับ horizon > 14 days
|
| 225 |
+
- Capacity analyzer ต้อง >= 50 good data points
|
| 226 |
+
|
| 227 |
+
### ข้อผิดพลาดที่หลีกเลี่ยง
|
| 228 |
+
❌ **ผิด**: Mix TEPR/STRR VALUES โดยตรง (MW + parameters มีขนาดต่างกัน)
|
| 229 |
+
✅ **ถูก**: ใช้ statistics (mean, std) เป็น features เท่านั้น

## 🎓 ตัวอย่างการวิเคราะห์
|
| 293 |
+
|
| 294 |
+
**Scenario**: โหลดจริง = 40 MW, 80% ทฤษฏี = 32 MW, อุณหภูมิ = 18°C
|
| 295 |
+
|
| 296 |
+
```
|
| 297 |
+
📊 Interpretation:
|
| 298 |
+
✅ Load % of 80% = 125% → โหลดเกิน 80%
|
| 299 |
+
✅ Thermal Margin = 12°C → margin อุณหภูมิเพียงพอ
|
| 300 |
+
✅ Available Margin = 0 MW → ไม่สามารถเพิ่มโหลดตามกำหนด 80%
|
| 301 |
+
⚠️ Action: ต้องลดโหลด หรือ recalibrate 80% baseline
|
| 302 |
+
```

📊 **ข้อมูล Diagnostics:**
|
| 187 |
+
- Data points: {len(df_with_analysis)} วัน
|
| 188 |
+
- Load MW: min={df_with_analysis['mw_max'].min():.2f}, max={df_with_analysis['mw_max'].max():.2f}, avg={df_with_analysis['mw_max'].mean():.2f}
|
| 189 |

- ✅ Data quality: OK (reasonable ranges)
|

⚡ **Capacity Analysis (ปัจจุบัน 80% ทฤษฏี):**
|
| 193 |
+
- โหลดจริง vs 80% ทฤษฏี: {df_with_analysis['load_pct_of_80'].mean():.2f}%
|
| 194 |
+
- Margin ที่ปล่อยเพิ่มได้เฉลี่ย: {df_with_analysis['mw_available_margin'].mean():.2f} MW ({df_with_analysis['margin_pct'].mean():.2f}%)
|
| 195 |
+
- Margin สูงสุด: {df_with_analysis['mw_available_margin'].max():.2f} MW

+
- Water Temp avg: {df_with_analysis['MaxTemp'].mean():.2f}°C
|

- **load_pct_of_80 < 100%**: โหลดจริง < 80% ทฤษฏี → มีโอกาสปล่อยเพิ่ม ✅
|
| 211 |

- **load_pct_of_80 ≥ 100%**: โหลดจริง ≥ 80% ทฤษฏี → ต้องระวัง ⚠️
|
| 212 |
+
- **Thermal Margin > 5°C**: ความมั่นคง thermal OK ✅
|
| 213 |
+
- **Available Margin > 0**: สามารถปล่อยเพิ่ม MW ได้ ✅

## 📋 8 ปัจจัยที่ขาดหายไป
|
| 16 |
+
|
| 17 |
+
### 1️⃣ **Data Quality & Validation** (คุณภาพข้อมูล)
|
| 18 |
+
|
| 19 |
+
**ปัญหา**: ข้อมูลบกพร่องทำให้ model bias
|
| 20 |
+
|
| 21 |
+
**ต้องวิเคราะห์**:
|
| 22 |
+
- Missing data percentage (เป้าหมาย < 5%)
|
| 23 |
+
- Outlier detection (load < 0 หรือ > 200 MW = ผิด)
|
| 24 |
+
- Duplicate rows
|
| 25 |
+
- Timestamp gaps (เช่น หายวันเต็มมี)
|
| 26 |
+
- Correlation matrix (load vs temp should correlate)
|
| 27 |
+
|
| 28 |
+
**ประโยชน์**: ❌ Bad data = ❌ Bad forecast
|
| 29 |
+
|
| 30 |
+
**Time to implement**: ⏱️ 2 ชั่วโมง
|
| 31 |
+
|
| 32 |
+
```python
|
| 33 |
+
def validate_data(df):
|
| 34 |
+
report = {
|
| 35 |
+
'missing_pct': (df.isnull().sum() / len(df) * 100).to_dict(),
|
| 36 |
+
'outliers': len(df[(df['mw'] < 0) | (df['mw'] > 200)]),
|
| 37 |
+
'duplicates': df.duplicated().sum(),
|
| 38 |
+
'correlation_load_temp': df[['mw_max', 'MaxTemp']].corr().iloc[0,1]
|
| 39 |
+
}
|
| 40 |
+
return report
|
| 41 |
+
```
|
| 42 |
+
|
| 43 |
+
---
|
| 44 |
+
|
| 45 |
+
### 2️⃣ **Temporal Patterns & Seasonality** (ลวดลายตามเวลา)
|
| 46 |
+
|
| 47 |
+
**ปัญหา**: Load ไม่เสม่ำเสมอตามวัน/สัปดาห์/เดือน
|
| 48 |
+
|
| 49 |
+
**ต้องวิเคราะห์**:
|
| 50 |
+
- Weekday vs Weekend (ต่างกัน 10-20%)
|
| 51 |
+
- Monthly seasonality (ฤดูร้อน vs ฤดูหนาว)
|
| 52 |
+
- Day of week pattern (Monday ≠ Sunday)
|
| 53 |
+
- Time of day effect (Peak ≠ Off-peak)
|
| 54 |
+
- Holiday impact (Holiday โหลด -30%)
|
| 55 |
+
|
| 56 |
+
**ประโยชน์**: +15-25% forecast accuracy
|
| 57 |
+
|
| 58 |
+
**Time to implement**: ⏱️ 3 ชั่วโมง
|
| 59 |
+
|
| 60 |
+
```python
|
| 61 |
+
df['day_of_week'] = df['date'].dt.dayofweek
|
| 62 |
+
df['month'] = df['date'].dt.month
|
| 63 |
+
df['is_weekend'] = df['day_of_week'].isin([5, 6]).astype(int)
|
| 64 |
+
df['is_holiday'] = df['date'].isin(holiday_list).astype(int)
|
| 65 |
+
|
| 66 |
+
# ใช้ features เหล่านี้ใน model
|
| 67 |
+
features = ['MaxTemp', 'day_of_week', 'is_weekend', 'month', ...]
|
| 68 |
+
```
|
| 69 |
+
|
| 70 |
+
---
|
| 71 |
+
|
| 72 |
+
### 3️⃣ **Thermal Dynamics & Lag Effects** (ความเป็นไปตามธรรมชาติของความร้อน)
|
| 73 |
+
|
| 74 |
+
**ปัญหา**: Cable ร้อนขึ้นช้า ไม่ใช่ทันที
|
| 75 |
+
|
| 76 |
+
**ต้องวิเคราะห์**:
|
| 77 |
+
- Temperature lag effect (24h, 48h ที่แล้ว)
|
| 78 |
+
- Rate of temperature change (dT/dt)
|
| 79 |
+
- Cooling curve (ท่อลดอุณหภูมิช้า)
|
| 80 |
+
- Accumulated heat over days
|
| 81 |
+
- Thermal time constant (cable responds in hours)
|
| 82 |
+
|
| 83 |
+
**ประโยชน์**: Capacity ที่ realistic มากขึ้น
|
| 84 |
+
|
| 85 |
+
**Time to implement**: ⏱️ 4 ชั่วโมง
|
| 86 |
+
|
| 87 |
+
```python
|
| 88 |
+
df['temp_lag_24h'] = df['MaxTemp'].shift(1)
|
| 89 |
+
df['temp_lag_48h'] = df['MaxTemp'].shift(2)
|
| 90 |
+
df['temp_change_rate'] = df['MaxTemp'].diff()
|
| 91 |
+
df['temp_rolling_3day'] = df['MaxTemp'].rolling(3).mean()
|
| 92 |
+
|
| 93 |
+
# Model better: ใช้ lag features แทน raw temp
|
| 94 |
+
```
|
| 95 |
+
|
| 96 |
+

|
| 97 |
+
|
| 98 |
+
### 4️⃣ **Cable Health Trend Analysis** (แนวโน้มสุขภาพสาย)
|
| 99 |
+
|
| 100 |
+
**ปัญหา**: TEPR/STRR ต้องวิเคราะห์ trend ไม่เพียง value เดี่ยว
|
| 101 |
+
|
| 102 |
+
**ต้องวิเคราะห์**:
|
| 103 |
+
- TEPR trend (degradation indicator)
|
| 104 |
+
- STRR trend (stress accumulation)
|
| 105 |
+
- Parameter stability (high std = unstable)
|
| 106 |
+
- Anomaly detection (sudden spike = alert)
|
| 107 |
+
- Spatial distribution (distance-based pattern)
|
| 108 |
+
|
| 109 |
+
**ประโยชน์**: Early warning system สำหรับ cable damage
|
| 110 |
+
|
| 111 |
+
**Time to implement**: ⏱️ 3 ชั่วโมง
|
| 112 |
+
|
| 113 |
+
```python
|
| 114 |
+
from scipy import stats
|
| 115 |
+
|
| 116 |
+
# Detect trend
|
| 117 |
+
tepr_trend = stats.linregress(range(len(df)), df['tepr_mean'])
|
| 118 |
+
tepr_slope = tepr_trend.slope # > 0 = degrading
|
| 119 |
+
|
| 120 |
+
# Anomaly detection
|
| 121 |
+
df['tepr_zscore'] = np.abs((df['tepr_mean'] - df['tepr_mean'].mean()) /
|
| 122 |
+
df['tepr_mean'].std())
|
| 123 |
+
df['is_anomaly'] = df['tepr_zscore'] > 3 # > 3σ = anomaly
|
| 124 |
+
```
|
| 125 |
+
|
| 126 |
+
---
|
| 127 |
+
|
| 128 |
+
### 5️⃣ **Load Characteristics & Volatility** (ลักษณะของโหลด)
|
| 129 |
+
|
| 130 |
+
**ปัญหา**: Load มี volatility ต่างกันต้องปรับ margin
|
| 131 |
+
|
| 132 |
+
**ต้องวิเคราะห์**:
|
| 133 |
+
- Load volatility (std/variance)
|
| 134 |
+
- Ramp rate (ความเร็วเปลี่ยนโหลด MW/hour)
|
| 135 |
+
- Peak to base ratio (max - min)
|
| 136 |
+
- Load duration curve (histogram)
|
| 137 |
+
- Autocorrelation (load repeats?)
|
| 138 |
+
|
| 139 |
+
**ประโยชน์**: Margin ที่ปรับตามความเสถียร
|
| 140 |
+
|
| 141 |
+
**Time to implement**: ⏱️ 2 ชั่วโมง
|
| 142 |
+
|
| 143 |
+
```python
|
| 144 |
+
df['load_volatility'] = df['mw_max'].rolling(7).std()
|
| 145 |
+
df['load_ramp'] = df['mw_max'].diff().abs()
|
| 146 |
+
df['load_range'] = df['mw_max'] - df['mw_mean']
|
| 147 |
+
|
| 148 |
+
# Adjust margin based on volatility
|
| 149 |
+
def adjust_margin(base_margin, volatility):
|
| 150 |
+
return base_margin + volatility * 0.5 # Add 50% of volatility
|
| 151 |
+
```
|
| 152 |
+
|
| 153 |
+
---
|
| 154 |
+
|
| 155 |
+
### 6️⃣ **Model Uncertainty & Confidence Intervals** (ความไม่แน่นอนของโมเดล)
|
| 156 |
+
|
| 157 |
+
**ปัญหา**: Forecast ต้องบอก uncertainty ให้ผู้ใช้รู้
|
| 158 |
+
|
| 159 |
+
**ต้องวิเคราะห์**:
|
| 160 |
+
- Confidence intervals (95%, 80%, 50%)
|
| 161 |
+
- RMSE/MAE (model error)
|
| 162 |
+
- Cross-validation scores (prevent overfitting)
|
| 163 |
+
- Backtesting on historical data
|
| 164 |
+
- Residual analysis (error distribution)
|
| 165 |
+
|
| 166 |
+
**ประโยชน์**: +40% trust จาก users (รู้ uncertainty)
|
| 167 |
+
|
| 168 |
+
**Time to implement**: ⏱️ 6 ชั่วโมง
|
| 169 |
+
|
| 170 |
+
```python
|
| 171 |
+
from sklearn.model_selection import TimeSeriesSplit
|
| 172 |
+
|
| 173 |
+
tscv = TimeSeriesSplit(n_splits=5)
|
| 174 |
+
scores = []
|
| 175 |
+
|
| 176 |
+
for train_idx, test_idx in tscv.split(X):
|
| 177 |
+
X_train, X_test = X[train_idx], X[test_idx]
|
| 178 |
+
y_train, y_test = y[train_idx], y[test_idx]
|
| 179 |
+
model.fit(X_train, y_train)
|
| 180 |
+
score = model.score(X_test, y_test)
|
| 181 |
+
scores.append(score)
|
| 182 |
+
|
| 183 |
+
# Confidence interval
|
| 184 |
+
residuals = y_test - model.predict(X_test)
|
| 185 |
+
ci_95 = 1.96 * residuals.std()
|
| 186 |
+
print(f"Forecast: 45 MW [95% CI: {45-ci_95:.1f}-{45+ci_95:.1f} MW]")
|
| 187 |
+
```
|
| 188 |
+
|
| 189 |
+

|
| 190 |
+
|
| 191 |
+
### 7️⃣ **Risk & Safety Margins** (ปัจจัยด้านความปลอดภัย)
|
| 192 |
+
|
| 193 |
+
**ปัญหา**: Capacity ต้องมี safety margin ไม่สามารถ 100% เต็มได้
|
| 194 |
+
|
| 195 |
+
**ต้องวิเคราะห์**:
|
| 196 |
+
- Sensor measurement accuracy (±%)
|
| 197 |
+
- Model forecast uncertainty
|
| 198 |
+
- Historical worst case (load spike)
|
| 199 |
+
- Failure modes (what if cable fails?)
|
| 200 |
+
- Degradation rate (capacity ลดลงตามเวลา)
|
| 201 |
+
- Maintenance windows (capacity ต่ำเวลา service)
|
| 202 |
+
|
| 203 |
+
**ประโยชน์**: Safe & reliable capacity ที่conservative
|
| 204 |
+
|
| 205 |
+
**Time to implement**: ⏱️ 5 ชั่วโมง
|
| 206 |
+
|
| 207 |
+
```python
|
| 208 |
+
def calculate_safe_capacity(theoretical_100pct, model_uncertainty):
|
| 209 |
+
"""Conservative capacity with safety margins"""
|
| 210 |
+
safety_factor = 0.95 # 95% of theoretical
|
| 211 |
+
model_margin = 1.96 * model_uncertainty # 95% CI
|
| 212 |
+
worst_case_margin = 5 # Always keep 5 MW buffer
|
| 213 |
+
|
| 214 |
+
safe_capacity = (theoretical_100pct * safety_factor
|
| 215 |
+
- model_margin - worst_case_margin)
|
| 216 |
+
return max(safe_capacity, 0)
|
| 217 |
+
|
| 218 |
+
safe_cap = calculate_safe_capacity(theoretical_100pct=50, model_uncertainty=2)
|
| 219 |
+
print(f"Safe Capacity: {safe_cap:.2f} MW (conservative)")
|
| 220 |
+
```
|
| 221 |
+
|
| 222 |
+

|
| 223 |
+
|
| 224 |
+
### 8️⃣ **Operational Context Integration** (บริบทปฏิบัติการ)
|
| 225 |
+
|
| 226 |
+
**ปัญหา**: ต้องเข้าใจการปฏิบัติการจริง
|
| 227 |
+
|
| 228 |
+
**ต้องวิเคราะห์**:
|
| 229 |
+
- Load demand forecast (user จะปล่อยเท่าไหร่)
|
| 230 |
+
- Maintenance schedule (capacity ลดระหว่าง service)
|
| 231 |
+
- Historical incidents (cable failures)
|
| 232 |
+
- Equipment ratings & specs
|
| 233 |
+
- Redundancy options (backup systems?)
|
| 234 |
+
- Control limits (hard & soft limits)
|
| 235 |
+
|
| 236 |
+
**ประโยชน์**: Recommendation ที่ practical & actionable
|
| 237 |
+
|
| 238 |
+
**Time to implement**: ⏱️ 1 ชั่วโมง

## 💡 ตัวอย่าง: ก่อน vs หลัง
|
| 317 |
+
|
| 318 |
+
### ❌ ปัจจุบัน (ไม่มีปัจจัยเพิ่มเติม)
|
| 319 |
+
```
|
| 320 |
+
Forecast: 45 MW
|
| 321 |
+
Available Margin: 5 MW
|
| 322 |
+
Recommendation: Can increase to 50 MW
|
| 323 |
+
⚠️ User: ไม่รู้ uncertainty → เสี่ยง overload
|
| 324 |
+
```
|
| 325 |
+
|
| 326 |
+
### ✅ หลัง (เพิ่ม 8 ปัจจัย)
|
| 327 |
+
```
|
| 328 |
+
📊 **Detailed Analysis:**
|
| 329 |
+
|
| 330 |
+
Data Quality: ✅ 98.5% complete
|
| 331 |
+
Seasonality: Winter pattern (-10% vs summer)
|
| 332 |
+
Thermal Status: Lag +1.2°C (heating slow)
|
| 333 |
+
Cable Health: TEPR trend ↑ +0.5/year (minor degradation)
|
| 334 |
+
Load Volatility: σ = ±3 MW (moderate)
|
| 335 |
+
|
| 336 |
+
🔮 **Forecast:** 45 MW [95% CI: 41-49 MW]
|
| 337 |
+
📈 **Model Accuracy:** RMSE = 1.8 MW (±4%)
|
| 338 |
+
⚙️ **Safety Factor:** 0.95 (conservative)
|
| 339 |
+
|
| 340 |
+
💰 **Recommendation:**
|
| 341 |
+
Safe Capacity: 42 MW (with 5 MW safety buffer)
|
| 342 |
+
Confidence: 85%
|
| 343 |
+
Caveats:
|
| 344 |
+
- +3°C temp → capacity drops 2 MW
|
| 345 |
+
- Maintenance Feb 15 → capacity 30 MW
|
| 346 |
+
- Model works best weekdays (±2% error)
|
| 347 |
+
|
| 348 |
+
✅ User: รู้ uncertainty & constraints → safe operation
|
| 349 |
+
```
