摘　　要：当电网容量充足时,削峰填谷不只是需求侧管理的唯一任务,利用电价机制引导用户合理用电、降低线损具有实际意义。将节能降损与电力需求侧管理相结合,通过建立电量与电价之间、网损与电量之间的函数,确定网损与电价的关系,利用电价引导消费者的用电行为,最终确定使得网损最小的最优电价。实例证明,最优电价模型与现有电价模型相比,对于降低网损有更直接的效果,对于电网节能有一定的参考意义。When the power grid capacity is sufficient,peak load shifting is not just the only task of DSM.Using price mechanism to introduce customers consuming power rationally and lowering line loss has practical significance.The paper combines power grid loss with DSM,determines the relationship between loss and price by establishing the functions between energy consumptions and price and the functions between loss and energy consumptions.By price to introduce customers power consumption action,the optimal price which makes loss least is determined.Examples show that optimal price model has better direct result compared with present price model to reduce line loss and has reference meaning for grid energy conservation.
