基于增强型鲸鱼优化算法的交直流互联配电网经济调度OA北大核心CSTPCD

With the continuous development of new energy and the wide application of power electronic technology,AC/DC interconnected distribution network technology has become the development direction of future distribution network.The reasonable and effective dispatch strategy of AC/DC interconnected distribution network can improve the proportion of new energy consumption and reduce the operation cost.An economic dispatch model of AC/DC interconnected distribution network is established,which takes the cost of equipment operation and maintenance,the operating cost of energy storage system,the cost of AC/DC bi-directional converter loss,and the power purchasing and selling cost between the distribution network and the power grid as the minimum.In order to effectively solve the model under the constraint of ensuring the safe operation of the distribution network system,an enhanced whale optimization algorithm(EWOA)is designed to dynamically update the constant b value of the limited logarithmic spiral shape,which improves the accuracy of the algorithm and accelerates its global convergence.The simulation calculation is conducted to verify the correctness of the constructed model and the advantages of the algorithm.The results show that the proposed algorithm has a faster convergence speed,stronger global convergence ability,and effectively reduces the economic cost of system operation.
