Robust and Scalable Power System State Estimation via Composite Optimization [article]

Gang Wang and Georgios B. Giannakis and Jie Chen
2019 arXiv   pre-print
Furthermore, by carefully mini-batching the voltage and power flow measurements, accelerated implementation of the stochastic iterations becomes possible.  ...  In today's cyber-enabled smart grids, high penetration of uncertain renewables, purposeful manipulation of meter readings, and the need for wide-area situational awareness, call for fast, accurate, and  ...  The novelty here is to fully exploit the sparsity of H m matrices to group measurements into mini-batches in a way that closedform solutions of the resulting quadratic programs are possible.  ...

Batching decisions: structure and models

Roelof Kuik, Marc Salomon, Luk N. van Wassenhove
1994 European Journal of Operational Research  
Batching is the clustering of items for transportation or manufacturing processing at the same time. Batching is also called lotsizing.  ...  In this way, batching typically generates cycle inventory or backorders. Still, batching can be advantageous for economic reasons.  ...  Models from queuing theory, (stochastic) dynamic programming, and mixed integer linear programming are the most prominent in the area of lotsizing.  ...
