SUMMARY:Smart-PGSim: Using Neural Network to Accelerate AC-OPF Power Grid 
 Simulation
DESCRIPTION:Paper\n\nSmart-PGSim: Using Neural Network to Accelerate AC-OP
 F Power Grid Simulation\n\nDong, Xie, Kestor, Li\n\nThe optimal power flow
  (OPF) problem is one of the most important optimization problems for the 
 operation of the power grid. It calculates the optimum scheduling of the c
 ommitted generation units. In this paper, we develop a neural network appr
 oach to the problem of accelerating the current optimal power flow (AC-OPF
 ) by generating an intelligent initial solution.\n\nThe high quality of th
 e initial solution and guidance of other outputs generated by the neural n
 etwork enables faster convergence to the solution without losing optimalit
 y of final solution as computed by traditional methods. Smart-PGSim genera
 tes a novel multitask-learning neural network model to accelerate the AC-O
 PF simulation. Smart-PGSim also imposes the physical constraints of the si
 mulation on the neural network automatically.  Smart-PGSim brings an avera
 ge of 49.2% performance improvement (up to 91%) with respect to the origin
 al AC-OPF implementation, computed over 10,000 problem simulations, withou
 t losing the optimality of the final solution.\n\nTag: Machine Learning, D
