风电场功率分配算法

在风电出力受限时,调度需要考虑多个风电场出力叠加所带来的平滑效应,优化功率分配。根据风电场是否具备风电功率预测系统建立了5种不同的风电场功率分配算法模型,以单个区域中的多个风电场的未来1 h功率预测数据来计算5种算法下所有风电场的总出力及相应的损失电量。结果表明,考虑预测的算法所得到的风电场出力情况与风力发电限值最为接近,且损失电量最少,明显优于不考虑预测条件下的算法。通过研究这5种算法也为风力发电的调度提供优化方案。

Study on algorithms of power curtailment among wind farms

When the wind power output is larger than the maximum system transfer capacity,wind power curtailment is required for operation safety.The smooth effect in multiple wind farms should be considered in power distribution.Five different wind curtailment algorithms were proposed based on the availability of wind power forecast system in a wind farm,and the models were established.The wind power outputs and losses were simulated according to hour-ahead power prediction data.Study results indicate that compared t...
