冰灾下考虑多重不确定性的负荷聚合商市场力评估方法
A market power assessment method for load aggregators considering multiple uncer-tainties under ice disasters
摘要
Abstract
In extreme scenarios,load aggregators may control the market to rake in excess profits.To address this,this paper proposes a market power assessment method for load aggregators considering multiple uncertainties under ice disasters.Firstly,the universal generating function(UGF)is used to describe uncertainties of faults on over-head lines and wind turbines under ice disasters.Secondly,by aggregating standard probabilistic functions of vari-ous uncertainties,the paper proposes a market power assessment operator to construct a market power assessment model for load aggregator nodes.Finally,based on the results of the clearance model,a spatiotemporal market power index system is constructed to identify key load aggregators with high market power levels and the correspond-ing critical periods.Case study results demonstrate that this method effectively quantifies the market power levels of load aggregators under ice disasters,and that load aggregators in regions with higher loads are more likely to exer-cise market power during severe icing periods.关键词
