BP神经网络对制冷蓄冷空调用电量预测分析

The Prediction and Analysis of the Electricity Consumption of the Refrigeration,Cool Storage and Air-conditioner with BP Neutral Network

我国经济迅猛发展,电力系统电负荷必须满足削峰填谷的需要。为了避开白天用电高峰,一些企业、写字楼、大型超市在夏季可以在夜间用制冷机制冷并且用蓄冷装置储存冷气,用于白天释放冷气。因为白天电价比夜间电价高,夜间用电可以为商家节省资金,减少当地白天用电量,促进当地经济建设。笔者基于MATLAB的BP神经网络分析某大型超市从2011年8月到2015年8月空调每日用电量,预测2016年8月夜间制冷机制冷所需的用电量,并且用蓄冷装置储存冷气,供白天使用。

With the rapid development of economy,the electric load of the electric system must satisfy the requirements of cutting peak and filling the valley.To avoid the electricity of peak in the daytime,some companies,large office buildings and large supermarkets may adopt refrigerator to refrigerate at night in summer and store the cold air with cool storage so as to release the cold air in the daytime.Since the electricity prices are higher in the day than that at night,using electricity at night might save fund for the merchants,which may reduce the local electricity consumption in the daytime and promote the construction of local economy.In this paper,based on the analysis of the daily electricity consumption for the air-conditioners in a large supermarket in august from 2011 to 2015by BP neutral network of MATLAB language,it is predicted the electricity consumption which the refrigerators need to refrigerate at night in august in 2016 and store the cold air with cool storages to supply the use in the daytime.
