Microgrid optimal operation considering electricity price fluctuations

With the progress of microgrid technique, more attention have be paid on the economy of microgrid operation other than the safety and stability of it. After the Prediction of Wind power(WP) and photovoltaic(PV), it will be easier than before to have optimal operation of microgrids so the constructor and the operator will save money. Considering the wavelet of electricity price, using mixed integer linear programming(MILP), an optimal power distribute method has been raised here. The simulation result shows the method will save the running costs.
