Generation planning using Lagrangian relaxation method and probabilistic production simulation

The mathematical model of generation planning program consists of two parts: the power plant investment decision and the probabilistic production simulation. Lagrangian relaxation method is applied to the power plant investment decision. The equivalent energy function method adopted extensively and successfully is used for probabilistic production simulation. Simulation results show that compared with the original JASP method, the new method can give more economical and rational system planning scheme.
