摘要
针对现有微电网柔性负荷的广泛渗透,同时考虑到通信网络存在传输延时,研究了一种基于一致性算法的微电网分布式经济调度方法。将发电机的增量成本和柔性负荷的增量效益选为一致性算法的变量,把系统的功率平衡作为收敛条件。在延时的情况下,通过分布式优化求解经济调度问题,实现了系统社会效益最大化的目的。仿真结果表明,所提的策略方法能解决含通信延时和柔性负荷的微电网社会效益最大化调度问题。
Aiming at the widespread penetration of flexible loads in the existing microgrid and considering the transmission delay of communication network,one distributed economic dispatching strategy based on consensus algorithm is studied.The incremental cost of generators and the incremental benefit of flexible loads are selected as the variables of the consensus algorithm,while the power balance of the system is taken as the convergence condition.Under the condition of time delay,the economic dispatch problem is solved by distributed optimization,and the social benefit of the system is maximized.Simulation results show that the proposed strategy can effectively solve the social benefit maximization scheduling problem of microgrid with communication delay and flexible load.
