摘　　要：针对目前微电网监控系统存在的协同性差、缺少动态配置支持、连续动态行为和离散事件共存的混杂性等问题,该文提出了一种基于设备网络服务框架(device profile for web service,DPWS)与解释Petri网模型的新型微电网监控方法。根据微电网监控系统功能需求,建立基于DPWS的分布式微源运行状态监控模型。利用DPWS技术的自动发现、自动组网机制对微电网监控系统进行重新配置,结合事件订阅机制实现微电网系统状态的实时监控,进而分析微电网系统在运行过程中的多重状态及其转换关系。基于DPWS技术信息加密机制,解决了微电网监控系统的信息传输安全问题。运用解释Petri网建立了微电网系统控制模型,提高了微网监控设备端的自动化程度,并完成了相应的数值仿真试验。试验结果表明,该模型能较全面地描述微电网系统中的并发及混杂现象,所提出的控制策略符合微电网系统实际运行要求,为微电网系统的安全、稳定地运行提供技术依据。Current micro-grid systems have problems of poor cooperation abilities and feeble dynamic configuration supports for network structure, and don’t cope well with the issues of coexistence caused by the continuous dynamic systems （CDS） and discrete event dynamic systems （DEDS）. In order to resolve the matter, a novel micro-grid monitoring network architecture based on the device profile for web service （DPWS） and interpreted Petri nets （IPN） was put forward to analyze the multiple states and the transform relations of different distributed micro sources during the running process of the micro-grid system. Referring to the function requirements and working characteristics of a micro-grid monitoring network system, an intelligent network architecture model for the mixed actions of distributed micro sources was set up. Based on the above model, according to the self-discovering/networking mechanism of DPWS for the target device, the dynamical configuration and automatic discovery for micro-grid system would be realized to improve the adaptive performance and intelligent level of micro-grid system. By the DPWS event subscribing interfaces and dynamical service methods, the distributed real-time monitoring was reached for the distributed micro sources in the micro-grid system. Based on the above research, the DPWS customized encryption mechanism and data transmission methods were combined to address the information security and working stability issues of the micro-grid system, and the simulated models for the monitoring system of the micro-grid were built up by using the IPN. Therefore, the automatic and intelligent level of the device terminal of the micro system were improved, and the running stableness and safety performance were enhanced. Based on the proposed methods, the corresponding numerical experiments were accomplished, and the results showed that the model could describe the concurrency and hybrid phenomena of a micro-grid system. The proposed control strategies can provide adequate self-a
