【摘要】：電力負荷是指一個地區(qū)對電力和電量的消費的情況。而農(nóng)村電網(wǎng)負荷預(yù)測是指從已知的農(nóng)村經(jīng)濟、社會發(fā)展和電力系統(tǒng)需求出發(fā),考慮農(nóng)村的經(jīng)濟、氣候和特殊事件等諸多因素,通過對農(nóng)網(wǎng)歷史數(shù)據(jù)的分析和研究,探索農(nóng)村電網(wǎng)系統(tǒng)各參數(shù)之間內(nèi)在聯(lián)系和發(fā)展規(guī)律,以未來的經(jīng)濟和氣候預(yù)測結(jié)果為依據(jù),對未來農(nóng)村電網(wǎng)需求做出估計和預(yù)測。農(nóng)村電網(wǎng)負荷預(yù)測是農(nóng)網(wǎng)管理系統(tǒng)的重要組成部分,它所提供的未來負荷數(shù)據(jù),對農(nóng)網(wǎng)系統(tǒng)的控制,運行和計劃極為重要。農(nóng)網(wǎng)系統(tǒng)由于設(shè)備比較陳舊,基礎(chǔ)設(shè)施薄弱,因而系統(tǒng)穩(wěn)定運行要求事先對負荷進行預(yù)測,才能早做準備,將設(shè)備資源進行合理調(diào)配,以保證農(nóng)村用電安全可靠。因考慮到電力負荷的區(qū)域特性,本文從年負荷、月負荷和日負荷三個方面分析了樅陽縣地區(qū)十二五期間負荷增長的特性,并著重分析了負荷的氣象敏感性和重大節(jié)假日影響,通過這些分析,得出了農(nóng)村電網(wǎng)負荷的一般特性。在分析電力負荷的基礎(chǔ)上,利用點對點倍比法、一元線性回歸法和BP神經(jīng)網(wǎng)模型對樅陽縣地區(qū)負荷進行短期負荷預(yù)測,并對三種負荷預(yù)測模型精度進行對比,得出適合農(nóng)村電網(wǎng)的短期負荷預(yù)測模型。其結(jié)果對農(nóng)村電網(wǎng)企業(yè)做好“迎峰度夏”和“迎峰度冬”的兩項重點工作有較好的參考意義。
[Abstract]:Power load refers to the consumption of electricity and electricity in a region, while the load forecasting of rural power grid refers to the consideration of rural economy from the known rural economy, social development and the demand of power system. Through the analysis and study of the historical data of rural power grid, the inherent relationship and development law among the parameters of rural power grid system are explored, which is based on the future economic and climate prediction results. Rural power grid load forecasting is an important part of the rural power network management system, it provides future load data, the control of rural power network system. It is very important to run and plan. Because the equipment is old and the infrastructure is weak, the stable operation of the system requires forecasting the load in advance so as to prepare and allocate the equipment resources reasonably. In order to ensure the safety and reliability of rural power consumption, considering the regional characteristics of power load, this paper analyzes the characteristics of load growth in Zongyang County during the 12th Five-Year Plan period from three aspects: annual load, monthly load and daily load. Through these analyses, the general characteristics of the rural power grid load are obtained. Based on the analysis of the power load, the point-to-point ratio method is used. The linear regression method and BP neural network model are used to forecast the short-term load in Zongyang county, and the accuracy of the three load forecasting models is compared. A short-term load forecasting model suitable for rural power grid is obtained. The results have a good reference significance for rural power grid enterprises to do the two key work of "summering peak" and "winter kurtosis".
