【摘要】 在电力系统中,平衡节点自动消纳负荷波动,从而保证了发电与用电实时平衡。本文在供求实时平衡的基础上,提出了一种带平衡节点的One-Less分布式经济调度算法。本算法中,所有节点均参与分布式计算,并执行经济调度指令;而平衡节点仅参与计算,不执行调度指令。本算法由平衡节点驱动,不需汇总供求差。在总负荷不变的条件下,本文利用线性系统理论证明了算法将收敛于成本最优值。仿真实验表明负荷突变与发电机饱和条件下本算法依然有效。更多还原

【Abstract】 Supply and demand balance of power system is ensured by slack point using automatic generation control in real time. Based on the supply-demand balance, this paper proposes a One-Less distributed economic dispatch algorithm with a slack point. The slack point participates in the algorithm without executing scheduling instructions, while the other nodes control the power generation in accordance with the algorithm. This algorithm minimizes the total generation cost of the power system under constant load condition, which is proved to be convergent by linear system theory. Finally, the algorithm is tested under conditions such as sudden load changes and generator saturation through simulation experiments.更多还原
