Abstract:This paper analyzed the effect factors of dynamic economic dispatch in
   wind power integrated system. Based on the full utilization of wind
   energy, the power output of thermal unit was optimized to obtain an
   optimum economic dispatch scheme. In the optimization model the
   constraints of up spinning reserve and down spinning reserve were
   introduced to deal with the influence of wind power forecast errors on
   dynamic economic dispatch, and valve point effect was considered in the
   objective function. A hybrid particle swarm and interior point
   optimization algorithm with smoothing technology was presented to solve
   the optimization model with the characteristics of non-differentiable
   and multi-peak-value. Numerical experiments demonstrate the rationality
   of optimization model and great practical value of proposed hybrid
   strategy.
