摘 要:臺風對電網(wǎng)負荷的影響具有不確定性和隨機性,傳統(tǒng)負荷預(yù)測結(jié)果往往不是很理想。結(jié)合福建電網(wǎng)的實際情況,歸納分析歷年影響福建電網(wǎng)的臺風活動規(guī)律,提出一種適合臺風期間的負荷預(yù)測方法。若存在可用相似日,考慮負荷年增長趨勢等因素,給出一種基于相似日修正的負荷預(yù)測方法;而針對無可用相似日的臺風,提出一種基準負荷修正的預(yù)測思路。研究表明,該預(yù)測方法能夠有效提高福建電網(wǎng)的短期負荷預(yù)測精度,具有一定的理論意義和應(yīng)用價值。
關(guān)鍵詞:短期負荷預(yù)測;臺風;相似日修正;基準負荷修正

Abstract: Due to the randomness and uncertainties of typhoon, traditional load forecast results are often not ideal. Based on the actual situation of Fujian power grid, this paper analyzed the typhoon activity pattern and proposed a short-term load forecasting method during typhoon. In the face of available similar days during typhoon, a forecasting method based on load modification of similar day was developed. In allusion to non-available similar days, this paper proposed the forecasting thought based on modification of reference day load. The research shows that this method could effectively improve the short-term load forecast accuracy of Fujian power grid, with certain theoretical significance and application value.
Key words: short-term load forecast; typhoon; modification of similar day load; modification of reference day load
