Abstract:

The opcration of distribution systems is one of the fundamcntal problems in modern powcr systems . The statc - of - the - art strategies are usually based on optimal power flow models that require accurate network parameters ( e . g , the network topology and branch impedances ). However , these parameters are often unavailable in many distribution networks . To address this issue , this alk iniroduces a data - driven nonparametric method for disiribution system operations . It lrains multi - layer percepiron ( MLP ) with ReLU activation functions based on historical metering data to learn power flow models , in which the requirement of network pa Г ameters can be bypassed . The trained MLP can be furthcr cquivalently reformulated into mixed - intcger linear constraints . As a result , the strategic opcration problem of distribution system based on data - driven ( black - box ) MLP models can be effectively solved by the Branch - and - Bound algorithm in off - the - shelf solvers . Considering that distribution neayork operation usualy faces significant uncertainties ( e . g ., renewable generation ), we further extend the proposed method tochan constrained proramming . In this extension , a data - driven quantile regresS1on neural network 1S trained to describe stochas power flow models . Similarly , it can be cquivalently reformulated into tractable mixed - intcgcr lincar constraints . experiments validate the effectiveness of the proposed nonparametric method .
