- Abstract
For achieving the market targets of improving efficiency, reducing costs, optimizing resources allocation and protecting environment, solving cost differences of different power plants and seasonal difference of hydropower because of history and so on, providing fair competitive environment for every power plants, achieving the goals of more hydropower output, improving utilization of large capacity and low emissions units, reducing pollutant and resources consuming, building hydro-thermal power replacement market is a great solving program. This also can balance the interests of all parties, and promote power upgrading of industrial structure. Because hydropower units' generation is constrained by the amount of inflow water, so it makes hydro-thermal scheduling have great uncertainty. Therefore, we need optimize hydro-thermal scheduling through related risk control tools. The paper constructs hydro-thermal power replacement model based on multi-objective CVaR theory. The paper also compares some nature of hydro-thermal power units generation replacement optimization by using VaR and CVaR.
