摘要: Abstract This paper presents a new modeling approach to incorporate operational characteristics of different types hydropower in long-term power sector models. The existing literature and methods were reviewed, the mathematical formulation developed model is presented. then used analyze future generation mix Nepal, country with huge untapped hydro resources, as case study. possible development pathway has been assessed through three electricity demand growth rate scenarios. optimal deployment indigenous renewables further evaluated by developing zero-emission scenarios conceivable policy strengthen national energy security. sensitivity analysis governing parameters evaluation simulation results was performed validate model. Simulation for capacity along emission level total system costs have discussed each scenario. Power dispatch operation schedule determined result optimization take account seasonal variations river inflow benefits hydropower. Sensitivity carried out examine impact construction cost, availability factor water storage on requirements
