With the increasing demand for energy, microgrid security is becoming more and more important. Therefore, how to monitor the microgrid effectively and continuously has received great attention. If the real-time on-line evaluation is realized, it is possible to improve the performance of power generation and load distribution. The current microgrid monitoring system is only to establish a monitoring center, and then send the information to the center through the equipment. However, staff need to be stationed in the monitoring center, the labor cost is too high. The scheme of microgrid monitoring system proposed in this paper makes a reasonable application of Aliyun technology. The information and data collected by the local device is passed into the gateway by specifying a unified communication protocol. The local device can provide the power, waveform and operation status of the whole power grid, in addition to displaying the power of the whole system, it also displays the power information of each element separately. The gateway then transmits the data through the optical fiber and wireless network to the CVM through the conversion protocol, and the operation of the microgrid can be monitored in real time by using external devices.
