In this paper, dynamic
economic dispatch model is proposed for power systems with bulk wind power integration.
The wind turbine generators are assumed to partially undertake the spinning
reserve for the thermal generator. A double-layer optimization model is
proposed. The outer layer use the differential evolution to search for the power
output of thermal generators, and the inner layer use the primal-dual interior
point method to solve the OPF of the established output state. Finally, the impact
of spinning reserve with wind power on power system operating is validated.
