As global carbon reduction initiatives progress and the new energy sector rapidly develops, photovoltaic (PV) power generation is playing an increasingly significant role in renewable energy. Accurate PV output forecasting, influenced by meteorological factors, essential for efficient management. This paper presents optimal hybrid forecasting strategy, integrating bidirectional temporal convolutional networks (BiTCN), dynamic convolution (DC), long short-term memory (BiLSTM), a novel mixed-state space model (Mixed-SSM). The mixed-SSM combines state (SSM), multilayer perceptron (MLP), multi-head self-attention mechanism (MHSA) to capture complementary temporal, nonlinear, long-term features. Pearson Spearman correlation analyses are used select features strongly correlated with output, improving prediction coefficient (

Due to the inherent intermittency, variability, and randomness, photovoltaic (PV) power generation faces significant challenges in energy grid integration. To address these challenges, current research mainly focuses on developing more efficient management systems prediction technologies. Through optimizing scheduling integration PV generation, stability reliability of can be further improved. In this study, a new model is introduced that combines strengths convolutional neural networks (CNNs), long short-term memory (LSTM) networks, attention mechanisms, so we call algorithm CNN-LSTM-Attention (CLA). addition, Crested Porcupine Optimizer (CPO) utilized solve problem generation. This abbreviated as CPO-CLA. first time CPO has been into LSTM for parameter optimization. effectively capture univariate multivariate series patterns, multiple relevant target variables patterns (MRTPPs) are employed CPO-CLA model. The results show superior traditional methods recent popular models terms accuracy stability, especially 13 h timestep. mechanisms enables adaptively focus most historical data future prediction. optimizes network parameters, which ensures robust generalization ability great significance establishing trust market. Ultimately, it will help integrate renewable reliably efficiently.
