摘    要:针对光伏充气膜温室自跟踪发电系统提出了一种加入天气预报信息的自适应变异粒子群神经网络的发电量预测算法.首先结合历史发电量数据和气象数据分析了影响光伏充气膜温室自跟踪发电系统发电量的主要因素,建立了加入天气预报的神经网络预测模型,并针对传统神经网络预测模型中基于梯度下降的BP算法收敛慢、易陷入局部最优、训练难收敛等问题,通过自适应变异粒子群算法改进了神经网络.该算法通过将变异环节引入粒子群优化算法,进行隔代进化找到局部最优解.实验结果表明所采用的自适应变异粒子群的神经网络预测算法的全局收敛性能得到了显著提高,能有效避免粒子群优化算法中的早熟收敛问题.

关 键 词:光伏充气膜温室  自跟踪发电系统  发电量预测  自适应变异粒子群神经网络算法

Abstract:A method which can forecast generating capacity of automatic tracking power system on inflatable membrane greenhouse attached photovoltaic was proposed based on the self-adaptive variation particle swarm neural network by adding with weather information. Firstly, through combining historical data of electricity production and meteorological data, the main factors of the impact on generating capacity of power generation system on inflatable membrane greenhouse attached photovoltaic was analyzed. Then, the neural network forecasting model was established by combining the weather forecast. The self-adaptive variation particle swarm algorithm was introduced to improve the training effect by tackling the problems of slowly converging, easily falling into local optimum, and difficultly converging existed in traditional neural network forecasting model based on gradient-descent BP algorithm. The neural network was optimized with adaptable mutation particle swarm optimization(AMPSO) algorithm. The mutation was put into particle swarm optimization(PSO) algorithm to find local optimal value. Experimental results showed that the entire convergence performance was significantly improved by adopting AMPSO and the premature convergence problem can be effectively avoided in PSO.
Keywords:Inflatable membrane greenhouse attached photovoltaic  Automatic tracking photovoltaic power generation system  Prediction of generating capacity  Self-adaptive variation particle swarm neural network algorithm
