非理想通信网络条件下的经济调度鲁棒协同一致性算法

Robust Collaborative Consensus Algorithm for Economic Dispatch Under Non-ideal Communication Network

考虑到实际通信网络中不可避免受到传输时延、噪声以及时变拓扑等因素的影响,提出一种计及非理想通信环境的经济调度鲁棒协同一致性优化算法。通过引入虚拟一致性变量,使得智能体之间的通信拓扑更加灵活,方便机组的即插即用,从而解决了时变拓扑下的一致性协同。在一致性计算中引入了一致性增益函数,有效抑制了传输噪声和时延。IEEE 39和118节点算例仿真表明:所提算法适用于非理想通信网络下的一致性经济调度,在保证收敛性的同时,可以获得较为满意的优化结果。

Considering the influence of transmission delay,noises and dynamically switching topologies in actual communication networks,an robust collaborative consensus algorithm for economic dispatch of non-ideal communication environment is presented.By introducing a virtual consensus variable,communications among smart units become more flexible as to enhance plug and play adaptability and consensus collaboration under dynamically switching topologies.With the assistance of a consensus gain function,the weakness of consensus-based algorithm to delays and noises in communication networks is eliminated.Finally,simulation results obtained from IEEE 39-bus and 118-bus test networks show that the proposed algorithm is suitable for the consensus economic dispatch of non-ideal communication network and satisfied optimization results can be obtained while the astringency is ensured.
