Abstract
It is becoming more and more difficult to construct large scale power plants because of environmental problems. Under such circumstances, demand side management for electricity conservation is expected to decrease the demand. However, we need a theoretical framework to introduce electricity conservation technologies into the power system.
In this paper, we have developed a model of Integrated Resource Planning, in which both electridc power stations and the conservation technologies are evaluated as resource of the power system. The model determines the share of electric power plants and conservation technologies by maximizing the social welfare function. As a result, we have derivated the condition, under which conservation technologies could constitute the system. We have also shown simple numerical example, utilizing data of insulation material of house. The result indicates that the insulation material could be a cost-effective resource if the cooling of houses is intensively done.
