由于陆用电力系统及传统船用电力系统的研究对象、运行要求和调控手段与综合电力系统不同，故二者的燃油经济性优化调度策略无法直接应用于综合电力系统。针对中压直流输电综合电力系统燃油经济性运行要求和能量调控手段的特点，本文提出基于改进下垂控制的综合电力系统燃油经济性优化调度方法。根据综合电力系统运行在最优点，发电机按剩余功率比例输出，发电机励磁控制环切换时扰动尽可能小的运行需求，通过系统燃油经济性模型计算系统最优点，给出希望的直流母线电压值，整定发电机励磁的改进下垂控制环的控制参数，实现综合电力系统燃油经济性的优化调度，并通过仿真试验验证了所提出方法的有效性。
Since the research objects, operational requirements and control methods of land power systems and traditional marine power systems are different from those of the integrated power system, the fuel economy scheduling strategies of the two cannot be directly applied to the integrated power system. Aiming at the characteristics of fuel economy operation requirements and energy control methods for medium voltage DC transmission integrated power system, this paper proposes an optimized power system fuel economy optimization scheduling method based on improved droop control. According to the operation of the integrated power system, the generator is output according to the residual power ratio. When the generator excitation control loop is switched, the disturbance is as small as possible. Through the system fuel economy model calculation system, the best advantage is given, and the desired DC bus voltage is given. The control parameters of the improved droop control loop of the generator excitation are realized, and the optimal scheduling of the fuel economy of the integrated power system is realized. The effectiveness of the proposed method is verified by simulation experiments.
