Wind power accommodation robust model considering demand response in enterprise microgird

With the development of wind power, how to use wind power fully has become an important research. In this paper, wind power accommodation robust model with security constraints considering demand response is built to accommodate wind power as much as possible. The robust model is a two-level optimal model: the upper level is to minimize the curtailed wind power and the lower level is to re-schedule the generator output to minimize the changed power between enterprise and the local grid for guaranteeing the grid safety. In order to solve the two-level model, it is equivalently transformed to single-level model. Finally, simulations are performed and the results show that such proposed approach can accommodate the uncertainty of wind power and electricity load and demand response can help to raise the utilization ratio of the wind power obviously.
