摘要
在微电网内进行点对点能源交易时,由于地理位置接近,用户间的信息交换密切,这会对用户的交易意愿和报价产生影响并最终影响交易出清。提出采用固定效应空间滞后模型研究代理商间交易意愿的空间交互效应,分析代理商交易意愿的空间溢出对周围代理商的影响,并通过市场均衡价格报价修正的双向拍卖机制有效论证考虑代理商交易意愿空间交互效应的报价策略对出清价格的影响。针对分布式发电的不确定性对实际电力交割阶段造成的问题,提出基于可靠性报价的联合交易模式,购电代理商以购电成本最小化进行自主交易。算例仿真结果验证了所提联合交易模式的可行性和有效性。
When performing peer-to-peer energy transaction in the microgrid,the information is closely ex⁃changed between the users due to the close geographical location,which affects the transaction willingness and quotation of the users and ultimately affects the transaction clearing.It is proposed to adopt the fixed effect spatial lag model for researching the spatial interaction effect of transaction willingness among the agents,the influence of spatial spillover for transaction willingness of the agents on the surrounding agents is analyzed,and the influence of quotation strategy considering the spatial interaction effect for transaction willingness of the agents on the clearing price is effectively demonstrated through the double auction mecha⁃nism which is corrected by the quotation of market equilibrium price.Aiming at the problems in the prac⁃tical electricity delivery stage caused by the uncertainty of distributed generation,a joint transaction mode based on reliability quotation is proposed,autonomous transaction of the electricity purchasing agents is car⁃ried out to minimize the electricity purchasing cost.The feasibility and effectiveness of the proposed joint transaction mode are verified by the example simulative results.
