【 摘 要 】

Based on the requirements of the economic reliability of the operation of islanded micro grid, a joint optimal dispatch model of the active power and reactive power of the islanded micro grid is proposed in this paper, which considers the constraints of upper and lower limits of output force and power balance of each micro source. In order to minimize the cost of operation and the penalty cost of voltage deviation of each node, an improvement is made on the basis of the original crow search algorithm, and combined with the advantages of the sine cosine algorithm, the improved sine cosine crow search algorithm is used to solve the model and the results of the active reactive power output of the island are obtained. The simulation results show that the proposed method can effectively control the voltage of each node in the micro grid within the allowable range, and is more beneficial to the economic operation of micro grid.
