Spinning reserve optimization in power system under power-limited of the wind farm
This paper proposed a research method based on wind farm power-limited operation. The wind farm power-limited part is treated as a special negative spinning reserve, and the interruptible load is used as a special positive spinning reserve, and the influence of this research method on the frequency modulation of the power grid is analyzed. It adopts the cost-benefit analysis method to establish the objective functions of start-stop cost of system, spinning reserve call cost, interruptible capacity cost, power-limited cost of the wind farm, constraint violation cost, generation cost, and the minimum target function. It divides several scenarios through the quantification of the power-limited value and the demand for large and small loads. And it adopts particle swarm optimization based on the mutation strategy combined with Monte Carlo simulation to solve this model. Meanwhile, considering the unit output distribution, and the solution accuracy of the model is improved. Finally, the calculation results of each scenario are analyzed to verify the superiority of the proposed optimization model.
