| To solve the current conventional energy depletion, environmental pollution such serious problems, a new power supply form microgird which composed by distributed power, energy storage devices, control equipment and load, and has the characteristics such as flexibility, safety, environmental protection shows in front of us. To ensure maximum play to its own advantage, this paper designed energy management system architecture. Taking full account of the characteristics of the microgrid itself and the differences between microgrid and main grid, wind power forecast software, load forecast software that take heat and cool into account and energy storage management software are added in the system; Analysised the prediction result that calculated by gray model, time series, artificial neural networks etc. Use wind speed changing limit to improve the forecast method for wind power forecast, and proved the correctness of the improving method. Achieved wind power forecast software development and used it to complete the simulation experiment of wind forecast。... |
