Distributed Power

In distribution networks with distributed power supplies, distributed power supplies can also be used as backup power sources to support the grid. If a distribution network contains multiple distributed power sources, the distribution network becomes a complex power grid with multiple power supplies. When a short-circuit fault occurs at a certain point on the power distribution network, the size, direction and duration of the short-circuit current are no longer single due to the existence of distributed power, and will vary with the location and capacity of the distributed power supply system. The change, in turn, affects the current in the grid, resulting in the generation and propagation of additional current. This power grid of power electronics will cause problems such as excessive standard mis-operation, abnormal heating of the converter and component burnout, and communication system failure. It is of great and practical significance to study the influence of distributed power in distributed power distribution networks.

Comprehensive Evaluation Method

In order to study the influence of distributed power access on the security state of distribution network, a comprehensive evaluation method for the security state of distribution network including distributed power access was proposed.Based on the output model and load model of photovoltaic power supply, the security situation assessment index system of distributed power supply access distribution network is established. Then combined with fuzzy analytic hierarchy process and entropy weight method, the composite weight of each index is obtained, and the combined weight is optimized based on chi-square distance. Finally, the evaluation method based on ER algorithm (Evidential Reasoning) is proposed. Simulation results verify the effectiveness and accuracy of the proposed method.

Power Quality Monitoring

The rapidly increasing usage of high-powered devices and the high specification in personal and industrial/medical devices has led to a greater demand for a SMPS for high-powered devices. A stable and reliable power source for such devices and research on power quality monitoring systems are needed. To these ends, this paper introduces a SMPS monitoring system based on ZigBee communication. The SMPS monitoring system uses ZigBee to collect the voltage, current, and temperature data from SPMS in real time. The collected data are visually synchronized and the current power supply status is displayed to the operator. In addition, to prevent any decline in the quality of the power, the system gives feedback via smartphone to the operator if errors are detected.
