The KEMS system is an information platform integrating computer technology, Internet technology, electrical automation technology, Internet of Things technology and communication technology for intelligent energy consumption dispatching and energy efficiency analysis management. The platform uses communication methods such as "Internet of Things" to collect data from energy storage power stations in all aspects and upload it to the cloud platform. By completing the statistical analysis of data through the cloud and combining it with the web terminal, real-time monitoring, early warning/alarm, energy storage dispatching, operation and maintenance and other functions of the power station can be realized. It can effectively monitor the operation faults of equipment and provide monitoring and control functions for microgrid systems containing distributed power sources such as photovoltaic power generation and energy storage units, optimize the operation efficiency of the power station and increase the revenue of the power station. The system can formulate corresponding optimization control strategies based on the current operation status of the microgrid system and external application requests. In view of the output characteristics of distributed power sources, reasonable energy management optimization technologies are adopted to enable the efficient utilization of distributed power sources and give full play to the low-carbon and economic advantages of the microgrid.
