【摘要】 针对微电网呈现出了交直流混合的拓扑结构，为实现考虑互联变换器的交直流混合微电网优化调度，综合考虑了分布式电源、互联变换器、储能装置等控制变量，以微电网的运行成本最低为目标函数，建立了交直流混合微电网优化调度的新模型。通过互联变换器的协调调度，一方面实现了微电网的电压稳定与功率平衡，另一方面大幅度减少了向上级电网的购电成本。由于所提出模型是计算复杂度高的混合整数非凸问题，将原模型转化为能够有效求解的线性化问题。最后，通过IEEE33节点系统验证了所提模型的有效性和求解的快速性。更多还原

【Abstract】 In response to the hybrid topology of AC and DC in microgrid, a new model for optimizing the scheduling of AC/DC hybrid microgrid considering interlinking converter was established by comprehensively considering control variables such as distributed power sources, interlinking converters, and energy storage devices, with the objective function of minimizing the operating cost of microgrids. Through the coordinated scheduling of interlinking converter, on the one hand, voltage stability and power balance of the microgrid are achieved, and on the other hand, the cost of purchasing electricity from the higher-level power grid is significantly reduced. Due to the high computational complexity of the proposed model, which is a mixed integer non convex problem, the original model is transformed into a linearization problem that can be effectively solved. Finally, the effectiveness and speed of the proposed model are verified through the IEEE33 node system.更多还原
