An Extensible Gradient-Based Optimization Method for Parameter Identification in Power Distribution Network

Algorithm 1

Adaptive gradient-based optimization methods.
Input: initial parameters
objective function to be optimized
, decay rates for moment estimates
initialized first-order moment
initialized second-order moment
time step
learning rate
maximum length of the simple moving average
While is not converged do
gradient with respect to parameters at time step
update first-order moment
update second-order moment
biased-corrected first-order moment
the length of the moving average
If the variance is tractable, i.e., then
   update the adaptive learning rate
   the variance rectification term
   update parameters
Else
  
End while
Return
