Microgrid Energy Bidding Transaction Model Considering the Uncertainty of Power Purchase Demand
摘要
Abstract
Microgrid can sell surplus resources in peak load to promote renewable energy usage and to get maximum benefit from them.The auction mechanism is adopted in the trading process,however the change of electricity purchase demand in the trading period also may affect the renewable energy usage and income of the microgrid.Accordingly,the paper has put forward a micro-grid energy auction transaction model that takes into consideration of the uncertain requirement of the power supply.The model adopts the unified price synchronous increasing auction mechanism for the price of electricity.It also puts forward an improved auction mechanism that balances the requirement of an energy purchaser in a different time period;Based on the uncertainty of energy demand,a linear op-timization algorithm was used.As a result,it was found that a robust linear optimal solution was obtained,which can maxim-ize the saleable renewable energy quantity and income of mi-crogrids by using MATLAB simulation analysis.关键词
