    摘 要:為了解決傳統(tǒng)超短期負(fù)荷預(yù)算方法誤差較大的問(wèn)題,提出一種基于局部模糊推理的區(qū)域電力系統(tǒng)超短期負(fù)荷預(yù)算方法。使用局部模糊推理定義利用的電力系統(tǒng)負(fù)荷歷史數(shù)據(jù),使用序偶法處理負(fù)荷數(shù)據(jù)的模糊集,計(jì)算數(shù)據(jù)的模糊度,得出時(shí)點(diǎn)負(fù)荷的偏離程度。規(guī)定特征時(shí)間尺度,依據(jù)特征時(shí)間尺度的數(shù)量關(guān)系,預(yù)測(cè)超短期隨機(jī)電荷分量,計(jì)算電荷分量的均值,形成新的負(fù)荷序列,平滑處理得到最終的超短期負(fù)荷預(yù)算表達(dá)式,完成對(duì)區(qū)域電力系統(tǒng)超短期負(fù)荷的預(yù)算。實(shí)驗(yàn)表明:與傳統(tǒng)基于BP 神經(jīng)網(wǎng)絡(luò)的短期負(fù)荷預(yù)算方法相比,基于局部模糊推理的區(qū)域電力系統(tǒng)超短期負(fù)荷預(yù)算方法誤差率只有0.07%,誤差更小,更適合預(yù)算區(qū)域電力系統(tǒng)的超短期負(fù)荷。

    Abstract: In order to solve the problem of large errors in traditional ultra-short-term load budget method, a regional power system ultrashort-term load budget method based on local fuzzy reasoning is proposed. Local fuzzy reasoning is used to define the historical load data of the power system, and the fuzzy set of load data is processed using the method of sequence coupling. The sequential couple method is used to process the fuzzy sets of load data, calculate the fuzziness of the data, get the deviation degree of the load at the time point. By specifying the characteristic time scale and predicting the ultra-short-term random charge component according to the quantity relationship of the characteristic time scale, the average value of the charge component is calculated to form a new load sequence, and the smoothing process is used to obtain the final ultra-short-term load budget expression, thereby completing the regional budget for ultra short-term load of the power system. Experiments show that compared with the traditional short-term load budgeting method based on BP neural network, the ultra-short-term load budgeting method of regional power systems based on local fuzzy reasoning has an error rate of only 0.07%, and the error is smaller, which is more suitable for the ultra-short-term load of the budgeted regional power system.
    Key words: local blur reasoning; regional power system; ultra-short term load; error rate
