摘要:

住宅屋顶作为一种闲置且几乎不受阴影遮挡的空间,为光伏系统的部署提供了理想条件。然而,光伏发电的波动性和间歇性,以及光伏发电与住宅用电之间在不同时间段的供需不匹配问题,使得住宅能源管理系统在实现供需平衡方面面临显著挑战。光伏发电预测作为能源系统优化调度和提升系统效率的重要环节,对于有效应对这些挑战至关重要。为此,提出了一种基于粒子群优化(PSO)算法与反向传播(BP)神经网络相结合的改进预测模型。该模型通过PSO优化BP神经网络参数,显著提高了光伏发电功率预测的精度和稳定性。试验结果表明,改进模型在四季的预测精度均优于传统BP神经网络,RMSE平均降低42.31%,R²平均提高2.22%,全年平均预测精度达到90.00%以上,其中冬季预测精度最高,为99.46%,为光伏住宅建筑光伏发电系统的优化调度提供了可靠的预测数据,具有重要的实际应用价值。

Abstract:

The residential rooftop,as an idle space that is almost free from shading,provides ideal conditions for the deployment of photovoltaic (PV) systems. However,the intermittency and volatility of photovoltaic generation,along with the mismatch between photovoltaic power generation and residential electricity demand at different times,present significant challenges for the energy management system in achieving supply-demand balance. As an essential component of energy system optimization and performance enhancement,photovoltaic generation forecasting is critical to effectively addressing these challenges. To this end,this paper proposes an improved forecasting model that combines Particle Swarm Optimization (PSO) with Backpropagation (BP) Neural Networks. In this model,PSO is employed to optimize the parameters of the BP neural network,significantly improving the accuracy and stability of photovoltaic power prediction. Experimental results demonstrate that the improved model outperforms the traditional BP neural network in forecasting accuracy across all seasons. The average root mean square error (RMSE) is reduced by 42.31%,and the coefficient of determination (R²) increases by 2.22%. The annual average forecasting accuracy exceeds 90.00%,with the highest accuracy achieved in winter,reaching 99.46%. This study provides reliable forecasting data for the optimized scheduling of photovoltaic systems in residential buildings,offering substantial practical application value.
