AIM-Technology model

AIM/Technology is a partial equilibrium energy system model characterized by detailed descriptions of energy technologies in both energy demand and energy supply sectors and was formerly known as AIM/Enduse. This document describes AIM/Technology V2.0, which was developed based on the AIM/Enduse framework [1]. The model structure and data for energy demand sectors are derived primarily from Akashi et al. [2] [3] with several updates, mainly in the energy supply sectors, based on AIM/Technology-Japan [4] [5], in which electricity dispatch is explicitly modeled in 1-hour steps. The following sections of this document describe the model structure of AIM/Technology, including its energy system representation, theoretical formulation, and socio-economic assumptions.
