Load demand forecasting is crucial for optimal energy management and sustaining comfortable indoor environments for air conditioning systems. The current research provides load demand prediction by a new modified rotor Hopfield neural network (RHNN) integrated with a fractional order of seasons optimization algorithm (FO-SOA) to overcome the challenge of predicting load demand. The RHNN extracts historical data patterning and predicts load demand prediction for future time using past data, and the FO-SOA includes infinitesimal calculus in its process to optimize its solution by considering repeating operation of honeybee agent and also extracting long-term memory operation without requiring additional memory access in the process to make it best at exploration/exploitation among optimization process. The model includes an incorporation model of key factors including ambient temperature, humidity, occupancy pattern, etc., for enhancing the reliability and the prediction accuracy. A case study validated the proposed RHNN/FO-SOA model and allowed for a comparison with several state-of-the-art methods, such as LSTM-based hybrid ensemble learning (LSTM/HEL), LSTM/RNN, deep neural networks (DNN), and deep learning models (DLM). The results showcase optimal performance, yielding an R value of 0.95, along with the lowest MSE, RMSE, and MAE values when compared to the other tested models. A correction coefficient increased the goodness of fit from 0.77 to 0.85. The RHNN/FO-SOA method may contribute to improve energy performance and reduce costs in air conditioners, shown by the findings.
负荷需求预测对于优化能源管理以及维持空调系统舒适的室内环境至关重要。当前的研究通过一种新的改进型转子霍普菲尔德神经网络(RHNN)与分数阶季节优化算法(FO - SOA)相结合来提供负荷需求预测,以应对负荷需求预测的挑战。RHNN提取历史数据模式,并利用过去的数据预测未来时间的负荷需求,而FO - SOA在其过程中包含微积分,通过考虑蜜蜂智能体的重复操作来优化其解决方案,并且在过程中无需额外的内存访问即可提取长期记忆操作,从而使其在优化过程中的探索/利用方面表现最佳。该模型包含一个关键因素的整合模型,包括环境温度、湿度、占用模式等,以提高可靠性和预测准确性。一个案例研究验证了所提出的RHNN/FO - SOA模型,并与几种先进方法进行了比较,如基于长短期记忆网络的混合集成学习(LSTM/HEL)、LSTM/RNN、深度神经网络(DNN)和深度学习模型(DLM)。结果显示出最佳性能,与其他测试模型相比,R值为0.95,同时具有最低的均方误差(MSE)、均方根误差(RMSE)和平均绝对误差(MAE)值。一个校正系数将拟合优度从0.77提高到了0.85。研究结果表明,RHNN/FO - SOA方法可能有助于提高空调的能源性能并降低成本。
