Chinese power sector is divided into six regions in this MESEIC (Multi-regional model for Energy
Supply system and their Environmental ImpaCts) model, with regional technology and resource
parameters. The model consists of Data Input, Objective Function, Constraints and Data Output, see Fig 1.
The objective function of the model to be minimized is the accumulated total cost of Chinese power
sector during the planning horizon, including generation costs and inter-regional power transmission cost.
The output of the model is the optimal pathways of Chinese power sector including installed capacity
development, generation composition, installations of emission control devices, fuel consumptions, CO2,
SO2, and NOX emission trends, demand for inter-regional power transmissions and total cost, both
nationally and regionally. All the actions are considered on a yearly basis
