基于黑板模型的配电网故障恢复多代理协作机制设计

Multi-agent Coordinated Mechanism Design of Distribution Network Fault Restoration Based on Blackboard Model

基于多代理理论,提出一种考虑负荷控制的含分布式电源配电网故障后快速恢复供电的多代理方法。构建了包含重要负荷代理、负荷全局控制代理、分布式电源代理、微电网代理的多代理系统,完成供电恢复策略的制定。引入黑板模型作为协调机制,并对黑板和知识库进行了模块化设计。恢复过程中每个代理寻找问题解部分,黑板组织协调各个代理行为,通过信息的更新与存储过程提高了信息利用率,这种协作机制既实现了并行计算,又避免了代理之间的不同步造成的信息滞留。算例表明,所述方法在处理配电网故障恢复问题时,恢复策略准确,速度快,具有高效性和实用性。

Taking distributed generator（DG） operating characteristics and load control features into consideration,a multi-agent method is proposed for quick fault restoration of the distribution network.The multi-agent system consists of the important load agent,global load control agent,distributed generator agents and microgrid agent.The blackboard model is used to build a coordination mechanism among the agents,each playing its part in seeking a solution.The blackboard model organizes and coordinates the agents＇behavior and enhances the information availability via the information update and store processes,not only realizing parallel calculation among the agents,but also avoiding information retention due to the out-of-sync state.The blackboard and knowledge sources are designed.Test results show that this method is highly efficient in giving an accurate and fast restoration strategy.
