摘 要:在風(fēng)電滲透率較高時,風(fēng)電場出力的波動在電網(wǎng)中形成擾動,會引發(fā)風(fēng)電接入點(diǎn)的潮流局部涌動和全區(qū)域電網(wǎng)的潮流全局竄動。針對局部特性的潮流涌動和全局性的潮流竄動,以常規(guī)機(jī)組出力和儲能為控制手段,提出了含風(fēng)電場的雙層協(xié)同調(diào)度模型。上層模型以調(diào)度周期內(nèi)電網(wǎng)改進(jìn)潮流熵的平均值最小為目標(biāo),下層模型以風(fēng)電場并網(wǎng)點(diǎn)在調(diào)度周期內(nèi)凈注入功率方差的平均值最小為目標(biāo)并采用NSGA-Ⅱ算法對所建模型交替迭代求解。含風(fēng)電場的IEEE39節(jié)點(diǎn)系統(tǒng)算例驗(yàn)證了調(diào)度方法的可行性和有效性。

Bilevel Cooperative Dispatch Considering Wind Power Penetration Based on Improved Power Flow Entropy

Abstract: When the penetration of wind power is high, the fluctuations of wind farm output will form disturbance in the power grid, leading to local surge of power flow in the grid-connected point of wind farm and overall volatility of power flow in the regional power grid. Aiming at local surge and overall volatility of power flow and taking the output of conventional units and stored energy as the controlling means, this paper proposed the bilevel cooperative dispatching model considering wind farms. In the upper model, the target is to minimize the mean of improved power flow entropy in the scheduling period, while in the lower model, the target is to minimize the mean of variance of the net injection of active power in all of the grid-connected points of wind farm in the scheduling period. The NSGA-II algorithm was adopted to calculate the built models alternately and iteratively. The case of IEEE39 node system verifies the feasibility and effectiveness of the proposed dispatching method.
          Key words: wind farm; fluctuation; power flow entropy; bilevel programming
