A comparison of low cost wireless communication methods for remote control of grid-tied converters

Remote control of grid tied converters has become important with an increasing number of grid connected energy storage systems. Hence, it is crucial point for utilities to outline the requirements of the communication methods and to find the best communication infrastructure to handle the remotely located converters in a reliable and cost effective manner throughout the operation. The purpose of this study is to come up with a low cost wireless communication solution for remote controlled converters. Focusing on low cost, this letter studies about three communication methods which can be applicable to control the remote converters. All three methods are being tested to find out the suitability for data communication. Then this paper provides a comparison of all three methods with cost, measured range and the data rate. And conclude that LoRa is the solution with the highest potential for this application from the compared methods.
