摘要
在电力局域网限速状态下,合理调度电力资源是解决网络拥堵的关键。电力网络信道资源调度过程中,为了保证调度的精度,调度过程被人为添加了过多的约束条件,用于描述局域网络限速过程。传统的信道调度方法在网络限速状态下资源调度的过程中,其多约束条件下的调度过程本身就是个矛盾的过程,由于约束造成了负载不均衡,资源调度效率不高。提出基于最大最小价格的分布式信道调度方法。分析了电力局域网限速状态下的信道调度原理,获取信道调度的约束条件。将信道调度问题分解成无需任何约束条件的非线性规划问题和有约束条件的线性规划问题,获取这两者信道传输方程,在信道的传输过程中采用最大价格的最大最小公平传输速率分配方法控制信道的调度,获取最优信道调度方案。实验结果表明,改进算法具有良好的调度性能。
A distributed channel scheduling method is presented based on maximum minimum price. The electric power network channel scheduling principle of limit state is analyzed, the channel scheduling constraints are obtained. The scheduling problem is decomposed into a nonlinear programming problem without any constraint condition and a linear programming problem with constraints, and the two channel transmission equations are got. In the process of channel transmission, the maximum minimum fair transmission rate allocation method is used based on the maximum price to control the channel scheduling, so as to obtain the optimal channel scheduling scheme. The experimental results show that the algorithm has good operation performance.
