In gas-fired power plants, emissions may reduce turbine blade rotation, thus
decreasing power output. This study proposes a hybrid model integrating the
Feed forward Neural Network (FFNN) model and Particle Swarm
Optimization (PSO) algorithm to predict gas emissions from natural gas
power plants. The FFNN predicts gas turbine nitrogen oxides (NOx) and
carbon monoxide (CO) emissions, while the PSO optimizes FFNN weights,
improving prediction accuracy. The PSO adopts a unique random number
selection strategy, incorporating the K-Nearest Neighbor (KNN) algorithm to
reduce prediction errors. Neighbor Component Analysis (NCA) selects
parameters most correlated with CO and NOx emissions. The hybrid model is
constructed, trained, and testedusing publicly available datasets, evaluating
performance with statistical metrics like Mean Square Error (MSE), Mean
Absolute Error (MAE), and Root Mean Square Error (RMSE). Results show
significant improvement in FFNN training with the PSO algorithm, boosting
CO and NOx prediction accuracy by 99.18% and 82.11%, respectively. The
model achieves the lowest MSE, MAE, and RMSE values for CO and NOx
emissions. Overall, the hybrid model achieves high prediction accuracy,
particularly with optimized PSO parameter selection using seed random
