156. Monitoring method of micro-grid based on DPWS network middleware and Petri nets.

Author

Zhang Libin, He Yuzhu, Xu Fang, and Tan Dapeng

Abstract

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-adapting monitoring services (automatic networking, dynamical configuration, automatic delete, inter-help service, intelligent linking, on-line remote access, large quantity stream data transmission, and automatic data storage) for the micro-grid system, meet the requirements of the micro-grid operations, and provide the technical references to guarantee safe and stable system running. As indicated in the paper, the modeling and analysis for the micro-grid system had high technical difficulties, and the paper performed the corresponding attempts for the area. The research results of the paper provides theoretical references and technical supports for the researcher and engineering in the regions of intelligent network, smart grid, condition based monitoring, and real-time data transmission. Further studies should be carried out on the facets of architecture model optimization, real-time data transmission protocols, IPN model improvement, and industrial field experiments.

158. Multi-String Photovoltaic Grid-Connected Inverter Based on Alternate Single-Phase PWM Control.

Author

Li, Xiaoyan, Zhang, Dairun, Li, Yuan, and Xu, Yang

Abstract

This paper presents a multi-string three-phase photovoltaic(PV) grid-connected inverter using a novel alternate single-phase current hysteresis PWM control method. In the multi-string PV grid-connected inverter, the maximum power point tracking(MPPT) of each PV array is independent, which leads to higher energy conversion efficiency. In the alternate single-phase PWM method, one line frequency cycle is averagely divided into six periods. Only one of the three-phase legs is switching based on PWM control and the devices in the other two-phase legs keep the switching state in each period. Therefore, the average switching frequency of the power devices is reduced to about 1/3 of that in a conventional three-phase PWM method, and the corresponding switching loss is reduced effectively. The efficiency of the whole system is improved further. Current hysteresis PWM tracking control can easily realize sinusoidal output current of inverter with fast dynamic response and good tracking performance. Unity power factor of grid-connected current can be obtained, and the system has good stabilization. The current total harmonic distortion (THD) is low and acceptable. The simulation results of Matlab prove the multi-string PV grid-connected inverter with the alternate single-phase PWM control is feasible and effective. [ABSTRACT FROM PUBLISHER]

Abstract

System protection is laid between the defenses for power system protective relaying and the emergency control. Under the premise of ensuring the safety of electrical equipment, it strives to ensure the safety of the system, block the chain of occurrence and growth of cascading faults, and effectively avoid the occurrence of large-scale blackout catastrophes. This book systematically elaborates on the dealing technology of a special type of fault, the “cascading fault”, in the AC-DC hybrid large-scale power grid. The main contents include immunization distance protection for accident overload; distance protection that is immune to oscillation; inverter control technology to prevent long-term or continuous commutation failure; DC participation emergency power flow control technology used to share the accident transfer overload caused by inverter lockout; and overhead transmission line adaptive overload protection.The basis of English translation of this book from its Chinese original manuscript was done with the help of artificial intelligence (machine translation by the service provider DeepL.com). A subsequent human revision of the content was done by the author.
