**Abstract**
In order to solve the economic dispatch problem of power system with wind power and
energy storage, the discrete particle swarm optimization (DPSO) algorithm is used to establish the
economic dispatch model of power system with wind farm based on chance constrained programming.
Discrete particle swarm optimization (DPSO) is used to calculate the minimum generation cost of
power system. In the calculation process, the processing constraints of engine group and climbing
power are taken into account. In order to verify the effectiveness of the discrete ion algorithm,
another algorithm is added to compare. The results show that at the same confidence level, the
expected minimum generation cost obtained by the discrete particle swarm optimization (DPSO)
algorithm is small, and the time consumed is short. It is a fast search algorithm with good
performance.
