全分布式储能照明系统运行优化

Operation Optimization of Lighting Systems with Fully Distributed Energy Storages

针对照明系统能效优化问题,提出了一种将储能装置与灯具相结合的全分布式储能照明系统,并对其进行优化调度研究。建立了全分布式储能照明系统的能量模型,重点研究了基于迭代的线损计算模型。在分时电价政策下,以储能装置充放电功率为控制量,分别建立了以最低成本、最低线损、最低综合指数为目标的照明系统最优调度方法。以某市政服务大厅照明系统为算例进行仿真,获得了3种优化调度策略的结果。与常规照明系统相比,通过对分布式储能照明系统进行优化调度最多可节省28.41%的购电成本,并可降低21.42%的线损。

In allusion to the problem of energy efficiency op-timization of lighting system,a fully distributed energy storage lighting system,which combined energy storage equipment with lamps and lanterns,was proposed,and the optimization scheduling of the proposed system was researched.An energy model of fully distributed energy storage lighting system was constructed and an iteration-based line loss computation model was emphatically researched.Under the TOU policy,taking the charging-discharging power of energy storage equipment as the controlled quantity,the lighting system optimal scheduling methods,which took the minimum cost,the minimum line loss and the minimum comprehensive index as objectives respect-ively,were established.The simulation,in which the lighting system for a certain municipal service hall was taken as com-puting example,was performed and the results of three optimiz-ation schedulings were obtained.Comparing with conventional lighting system,by means of carrying out optimization schedul-ing of distributed energy storage lighting system,up to 28.41%of electricity purchasing cost can be saved and 21.42%of line loss can be reduced.
