Optimal Hour-Ahead Scheduling of Micro-Grid Considering Wind Power Uncertainty
Journal Title: 河南科技大学学报（自然科学版） - Year 2019, Vol 40, Issue 1
Abstract
The supply of the micro-grid was the coordination of wind power generator and fuel/gas generator.Because the wind power generation in the next hour cannot be predicted accurately, the uncertainty will largely affect the accuracy of hour-ahead scheduling. Therefore, the risk management model based on the information gap decision theory ( IGDT) was proposed in the supply side. And an optimal hour-ahead electricity price was designed by the predictor corrector proximal multiplier ( PCPM) algorithm. The demand response mechanism based on the price maximized the profit of the demand side, the supply side and the society. In the meantime, the region where the wind power generation was permitted to fluctuate was maximized. Therefore, the supply side was protected from the risk from the uncertainty of wind power generation. Finally, the effectiveness of the optimal hour-ahead scheduling in micro-grid was validated by the numerical simulation example.
