Research On The Energy Dispatch In Microgrid And Software Development

Nowadays,the air pollution in China is serious.In order to meet the demands of environment protection and energy saving,the growth rate of renewable energy would be as high as before in next few years.That also can improve the energy supply structure of China.As is known to all,microgrid is an effective system for integrating distributed generations,energy storages,loads and some auxiliary devices.So microgrid can do a lot of utilization of electricity power,which could play a role in renewable energy development.At present,the increment of electricity power in China is slow down and the demand of use-side is going to be focused on.Energy dispatch and operation mode in microgrid are mainly discussed in this paper.First,the typical structure of microgrid and several key technologies for energy dispatch are introduced.Second,the methods of output forecasted of renewable energy and predicted load are analyzed and compared.The final choice of forecasting is the method of mathematics forecasting.Third,according to the features of microgrid,mathematical model is established and the simulation of energy dispatch are tested in Matlab.Forth,the software is designed in Qt so that the management in microgrid is more convenient than before.At last,combined with the experience of domestic and foreign country,two typical kinds of microgrid operation mode are put forward.
