摘要 为了解决风电接入后的电力系统动态经济排放调度问题,首先提出了风电机组的出力模型,并结合风电前期投资和后期维护成本折算的风电发电成本,风电的波动引起的系统的备用容量补偿成本,火电机组的发电成本和排污导致的环境补偿成本模型,建立了满足各种约束条件下的动态经济排放调度模型,然后针对标准差分算法易陷入局部最优解的问题,利用了一种约束满足度来进行解的比较的水平比较差分进化算法来求取系统最小运行费用,最后通过了IEEE 39节点算例验证所提出模型和算法的正确性。 To solve the schedule problem of power system dynamic economic emission including wind power, a wind power output model was proposed firstly. Combining wind power generation cost converted by wind power investment and maintenance expenditure, system reserve capacity compensation cost caused by wind power fluctuation, thermal unit generation cost, and environmental compensation cost, the dynamic economic emission schedule model which met all kinds of constraint conditions was then established. The algorithm of differential evolution with level comparison which applied constraint satisfaction degree for solution comparison was presented to calculate the system minimum operation cost due to standard difference evolution algorithm easily fell into local optima. At last, the example of IEEE 39 bus system verified the proposed model and algorithm.
