As one of power prices to consumers , tou ( time - of - use ) power price is applied in many countries in the world , and it is one of the important methods of dsm ( demand service management ) . it can accomplish the goal of load shifting and reducing costs of power consumers 作为用户侧电价的一种,分时电价目前在世界各国得到了广泛的应用,而且分时电价是需求侧管理的一种重要手段,可以达到削峰填谷与减少用户购电费用的目的。
Simulation results show that tou power price determined in this paper can achieve the objective of load shifting and reducing costs of power consumers . compared with existing work , tou power price determined in this paper can get better effect of load shifting and reducing costs of power consumers 仿真结果表明,本文确定的分时电价可以达到削峰填谷和减少用户购电费用的目标,与现有工作比较,本文方法确定的分时电价可以达到更好的削峰填谷作用,使用户购电费用更小。
In this paper determination of tou power price is studied and three approaches are brought out : use mcp ( market clearing price ) to determine flat load ' s power price , then determine the power price of peak and valley loads ; determine power price of peak , flat and valley loads according to optimization of load shifting ; determine power price of peak , flat and valley loads according to load shifting and reducing costs of power consumers 本文对分时电价的确定进行了探索性研究,提出了确定分时电价的三种方法:用市场清除价确定平时段电价,然后在此平时段电价基础上确定峰、谷电价;根据削峰填谷最优同时确定峰、平、谷时段电价;根据削峰填谷和用户购电费用最佳均衡同时确定峰、平、谷时段电价。
And it is calculated and analyzed the distribution and quantity of slag thermal stress created by boiler load shift . thermal stress quantity can be as big as e / 1000 and is enough to destroy slag structure and to make some drop . it is also concluded that the walltube parameters can only affect on thermal stress of the slag that is near to contact surface and contribute little to slag drop 针对锅炉变负荷运行时炉膛的自然掉渣现象,分析锅炉水冷壁渣层中热应力的产生机理,建立了水冷壁渣层热应力的计算模型,计算分析了锅炉大范围变负荷运行产生的渣层热应力变化大小和分布,并分析渣层热应力的影响因素。
The feeder automation technology which based on the feeder terminal unit ( ftu ) is a key technology and the core content of distribution network automatization , and it realizes all the distribution network real - time monitoring by ftu , communication network and coordinated operation of power distribution automatization master station system . when the breakdown occurs , it can rapidly carry on the breakdown localization , and realize the failure isolation and the load shift with the master station system participation , thus it completes the network reconstruction 基于馈线终端单元( ftu )的馈线自动化技术是配电自动化的一项关键技术和核心内容,通过ftu 、通信网络和配电自动化主站系统的协调运行实现对整个配电网的实时监控,当故障发生时,能够迅速进行故障检测、定位,并在主站系统的参与下实现故障隔离及负荷转移,从而完成网络重构。
