微电网可以将发电高峰期盈余的可再生能源出售来促进可再生能源消纳并获取最大收益.采用拍卖机制确定交易价格,但交易过程中购电需求的变化也会对可再生能源消纳及微电网收益产生影响,为此,提出一种计及购电需求不确定性的微电网能源竞价交易模型.首先采用统一价格同步向上叫价拍卖机制进行定价,并提出了拍卖机制的改进方案来平衡用能消费者的对不同时段的拍卖需求;考虑到用能消费者的购电需求不确定性,采用鲁棒线性优化算法来规避不确定性参数对最优解的影响.最后通过MATLAB软件仿真分析,证明了该模型能够最大限度地提高可再生能源的出售率及微电网的收益.
Microgrid Energy Bidding Transaction Model Considering the Uncertainty of Power Purchase Demand
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.
