【摘要】：為了解決風(fēng)電出力的不確定性給電網(wǎng)安全運行帶來的威脅,提出基于快速傅里葉變換(FFT)快速計算卷積化簡機(jī)會約束規(guī)劃的動態(tài)經(jīng)濟(jì)調(diào)度算法.針對多個風(fēng)電場同時接入系統(tǒng)的復(fù)雜情況,在風(fēng)電出力概率和負(fù)荷預(yù)測的基礎(chǔ)上,保證正、負(fù)旋轉(zhuǎn)備用能滿足負(fù)荷和風(fēng)電實際出力的波動,應(yīng)用機(jī)會約束規(guī)劃建立了考慮失負(fù)荷和棄風(fēng)風(fēng)險的含風(fēng)電場電力系統(tǒng)動態(tài)經(jīng)濟(jì)調(diào)度模型;利用FFT快速計算卷積求取聯(lián)合變量的概率分布以將機(jī)會約束轉(zhuǎn)化為確定性約束簡化得到確定性模型,并用CPLEX進(jìn)行求解,該方法大大減少了算法的運算時間.以修改的10機(jī)39節(jié)點系統(tǒng)為算例驗證了所提調(diào)度模型的正確性及化簡方法的有效性.
[Abstract]:In order to solve the uncertainty of wind power generation to the security of power grid operation threats. This paper presents a dynamic economic scheduling algorithm based on Fast Fourier transform (FFT) to calculate convolution simplification opportunity constrained programming, aiming at the complex situation where multiple wind farms are connected to the system at the same time. On the basis of wind power output probability and load forecasting, it is guaranteed that positive and negative rotation reserve can meet the fluctuation of load and actual wind power output. The dynamic economic dispatching model of power system with wind farm is established by chance constrained programming considering the loss of load and the risk of wind abandonment. The probability distribution of the joint variables is calculated quickly by FFT to simplify the chance constraint into the deterministic constraint and the deterministic model is solved by CPLEX. The computational time of the algorithm is greatly reduced. The correctness of the proposed scheduling model and the effectiveness of the simplified method are verified by a modified 10-machine 39-bus system.
