摘　　要：该文对包含发电设备、产水设备和电水联合生产设备的混合能源网络建立资源经济调度问题的非线性规划模型。针对这类考虑水电生产复杂关系的优化问题,提出一种连续时间分布式算法来寻找经济调度问题的最优解。收敛分析表明,该算法能够在任意初始条件下收敛到最优解,且不需要设备与相邻设备交换成本函数的梯度信息,能够很好地保护设备的隐私信息。最后,数值仿真实验结果验证了求解混合能源网络中资源调度问题算法的性能和有效性。In this paper,a mathematical model is firstly built for economic dispatch of a hybrid resource system consisting of power plants,water plants,and coproduction plants.For this kind of optimization model considering the complex relation of the power and water in production,a continuous-time distributed algorithm is proposed to find the optimal solution of the economic dispatch problem.The convergence analysis shows that the trajectories converge to the optimal solution regardless of the initial allocation,avoiding the consideration of the initial procedure in detail.Moreover,applying the proposed algorithm,the plants no longer need to exchange the gradient information of the cost functions with their neighbors,which can protect the privacy of the plants.Finally,a numerical example is provided to demonstrate the performance and effectiveness of the proposed algorithm for the energy-water nexus.
