Abstract： An improved particle swarm optimization （PSO） is proposed to overcome the difficulties of short?term hydrothermal power generation scheduling， such as more decision variables， high dimension， large scale， no convex， nonlinearity and difficult solution. In this algorithm， the backward learning strategy is used to improve quality of initial solutions， the parameter adaptive dynamic adjustment mechanism is established to control the swarm evolution process， and the chaotic local search method is introduced to enhance the algorithm's local optimization capability. At the same time， according to different types of constraint conditions， a method that can effectively deal with multiple complex constraints is adopted. The simulation results verify the feasibility and effectiveness of the proposed algorithm and the constraint handling method， which provides an efficient and practical new method for solving the joint scheduling problem of hydrothermal power system.
