| Abstract: |
| An energy optimization model of microgrid with ES(Electric Spring) is proposed. Since ES is a medium for load regulation of microgrid, a regulation model of smart load is established based on non-critical load characteristics. According to wind power output and various load forecasting curves, the energy optimization model is analyzed and calculated, and the role of ES in energy optimization of microgrid is quantitatively analyzed with the consideration of charging and discharging cost of energy storage, abandoned wind cost, depreciation cost of ES equipment and load regulation subsidy. Case and simulative results verify the correctness and effectiveness of the proposed model. |
| Key words: microgrid electric spring charging and discharging cost abandoned wind cost energy optimization model |
