A Study on the Framework of Advanced Demand Side Management Using Information Technology

为了利用自然资源，减轻环境影响，需求侧管理正引起人们的关注。电力需求侧管理是实现电力系统节能的有效手段。在本研究计画中，探讨未来需求侧管理系统应该是什麽样的。应利用信息技术来满足每个客户的要求。该系统必须与放松管制（或自由化）的电力供应系统相兼容。首先，研究了“用户行为建模”和“用户实现有效需求侧管理的菜单”。由于储能系统目前非常昂贵，因此利用储能系统提高供电可靠性可能会对社会福利产生负面影响。将选择性弃负荷看作是一种多品质供电。其次，研究了直接设备控制与间接控制与电价相结合的真实的实时需求侧管理。将带奖金的需求侧管理视为一种间接控制，对这种管理的有效性进行了检验。由于大量的消费者可以参与需求侧管理，并获得奖金，因此可以预期会产生很大的效果。所提出的真实的时间需求侧管理的效果如下：-消费者效用几乎没有降低。减少了供电系统的设备投资。社会福利有所增加。可以减少CO2排放。

In order to utilize natural resources, and to mitigate environmental effect, demand side management is drawing attention. With Demand Side Management, it is expected that the energy conservation in electrical energy supply system can be achieved. It is also expected that equipment investment can be reduced.In this research project, what a future demand side management system should be is discussed. The information technologies should be utilized to fulfill each customer's request. The system must be compatible with the deregulated (or liberalized) electrical energy supply system.First, "modeling of consumer behavior" and "menu for consumer to realize effective demand side management" are studied. Since the energy storage system is very expensive so far, it might be probable that improving supply reliability with energy storage system has negative effect on social welfare. Selective load curtailment is considered as a kind of multiple quality power supply.Second, the real time demand side management, a combination of direct equipment control and indirect control with pricing, is studied. The effectiveness of the demand side management with bonus, which is considered as a kind of indirect control, is examined. Since a large number of consumers can participate in the demand side management with bonus, big effect can be expected. The effects of the proposed real time demand side management are as follows :-Consumer utility is little reduced.-Equipment investment in electric energy supply system is reduced.-Social welfare is increased.-CO2 emission can be reduced.
