Abstract: Traditional stand-alone Micro-grid depends on control center to coordination control, relys solely on the regulating ability of battery to stabilize the system energy and the start-stop of Diesel depend entirely on the load.
Because of the volatile characteristics of distributed power supply, the batterys conducts charging-discharging operations frequently and also the Diesel’s start-stop will be irregular and frequent, it greatly shorten the life of the battery and Diesel, the system can’t make full use of the distributed power supply and greatly depends on fossil fuels , so the system has low efficiency. This paper presents a method based on load curve control to manage and optimize configuration of devices for the stand-alone Micro-grid, use energy rationally according to the schedule, it can maximumly plays the role of distributed power supply and prolong the life of device in the system effectively.
