Abstract: In multicast routing comunication of smart grid, concerning the long communication delay of multicast tree when transmitting control messages to high-power load device, which caused by only considering delay constraint without considering the demand of smart grid, a new multicast tree construction method that considered load and comunication delay at the same time was proposed, namely multicast routing algorithm based on Demand Response (DR) capability constraint. Firstly, a complete graph satisfying the constraint was generated according to the grid network topology. Then, a lower-cost multicast tree was constructed by using the Prim algorithm. Finally, the multicast tree was restored to the original network. The simulation results show that the proposed algorithm can effectively reduce the demand response delay of high-power load devices, and can significantly reduce the power frequency deviation compared with the multicast routing algorithm only considering delay constraint. This algorithm can actually improve the real-time demand response in the smart grid and stabilize the grid frequency.

摘要: 针对智能电网多播路由通信中,通常存在只考虑多播通信的时延约束而没有考虑电网需求侧带负载的情况,所构建的多播树会出现控制信息传输到大功率负载设备的通信时延较大的问题,提出一种考虑负载功率和通信时延的多播树构造方法,称为基于需求响应(DR)能力约束的多播路由算法。首先,根据电网拓扑信息生成满足约束条件的完全图;然后,采用Prim算法构造较低费用的多播树;最后,将多播树还原到原网络。仿真结果表明该算法能够有效地减小大功率负载设备的需求响应时延,与基于时延约束的多播路由算法相比,能够使电网频率波动大幅度减小。该算法能够有效地提高智能电网中需求响应的实时性,稳定电网频率。
