Hydrothermal Short-Term Optimal Scheduling in the Low-Carbon Economy

The aim of Low-carbon economy is to decrease the emissions of CO₂.The CO₂ that let out by the thermal power system takes a considerable part. Hydrothermal power dominant in the power source in China,so it has an important meaning to research optimal dispatching of hydrothermal system. The problem of short-term scheduling of hydrothermal power system optimization is a complex, non-convex, nonlinear problem.lt is solved by genetic algorithm in this paper , which takes water volume, water inflow, water discharge, effective water head, and output of power into account. A model is proposed considering both maximum generation benefit and minimum CO₂ emissions. Finally, through the simulation of a true hydrothermal system, the analysis results of the example show that the model and genetic algorithm are available and effective.
