提出了一种多端背靠背柔性互联系统的负载均衡方法,首先搭建了多端背靠背柔性互联系统模型,定义了动态负载率、负载跟随度等指标,建立了从单馈线到多馈线的负载均衡指标体系,以及负载均衡的多目标评价模型。其次,结合搜索范围大、精度高的改进布谷鸟算法,对多端背靠背柔性互联系统负载均衡方案进行了优化。最后,在MATLAB上搭建算例,验证了多端背靠背柔性互联系统进行负载均衡的可行性与有效性,以及使用动态负载率等指标进行评价必要性。
This paper proposed a load balancing method for a multi-terminal back-to-back flexible interconnection system.Firstly,the flow control model of multi-terminal back-to-back flexible interconnection system is established,and the dynamic load rate,load following degree,feeder load evaluation coefficient and other indexes are defined.The load balancing system from single feeder to multiple feeder is established.Secondly,the improved cuckoo search with large searching range and high precision is optimized for the balanced system solution of multi-terminal back-to-back flexible interconnection system.Finally,an example is given on MATLAB to verify the necessity of dynamic load rate of multi-terminal back-to-back flexible interconnection system,the feasibility and effectiveness of load balancing.
