摘　　要：针对电网可靠性问题,给出了一种可在线确定电网最佳运行方式的启发式算法。该算法结合电网的实际运行情况,引入负荷节点总有功对支路有功系数的灵敏度,并依据灵敏度绝对值的排序,通过精确计算和比较来实现电网最优运行方式的在线确定。该方法缓解了电网在线优化计算中速度和精度之间的矛盾,且物理概念清晰,易于编程实现。A heuristic algorithm is used in the the reliability of the electric network. With sensitivity of the total active power of load introduced. Based on the sorts of sensitivity obtained with the precise calculation and on-line determination the actual condition of the optimal operation for of the electric network, the nodes to the branch active power coefficient is absolute values, the final optimization program is comparison. With clear concept and simple programming in the described approach, the contradiction between computation speed and precision in on-line optimization calculation is also solved.
