摘要
本文提出了一种求解大规模水火电力系统最优经济调度问题的多层次预估算法。该算法的特点是问题的关联量均被预估,从而使计算简单、快速、边界和终端约束问題容易求解.在所考虑的问題中包含了火电站、不变水头水电站、变水头水电站和有水力联系的梯级水电站,并考虑了水量传输中的时间滞后,电力传输损失和其它实际约束.实例计算结果表明该算法计算方便,快速,是一种有效的实际工程算法.本文还给出了该算法收敛性定理.
In this paper,a now muitilevel predtction methed has been given to solve the optimal cconmic dispatch ptoblem of large-cale hydrothermal power systems.The characteristic of the algorithm is that the inteautlve quanties in the problem are predicted thoroughly,thus the compation is simple and tasr and the problems of bound constraints and the final-value consuaints are solved easity.The problem considered includes thermal plants,fixed-head hydro plants,variabl head hydro ptants,hydraulic networks with cascade hydro plants, time delays involed in water transport,transmission losses involved in electic transport and other realistic constranits.A practical exanple is solved to compare the computational efficeency of this algorithm with that of a current one.The results show that this algorithm is much faster and more convenient.This algorithm is an efficrent praeucal engineering method.The theorem of convergence of the new algorithm is given in this paper
