Power Flow Solution Based on Deep Convolutional Neural Network
The Problem
Power system flow equations have traditionally been solved by model-based analytical methods. Increasing resources being introduced into power grid systems has presented challenges to conducting accurate system modeling. This strain requires significantly more flow calculations. Traditional model-based power system flow calculation methods may experience significant computational burdens and fail to meet real-time and multi-scenario analysis requirements. These analytic methods are likely to fail in instances of resource integration on a large scale or dimension.
The Solution
Researchers at the University of Tennessee have developed a novel data-driven method for power flow calculation based on deep convolutional neural network (CNN) as an efficient alternative to the traditional model-based method. No algebraic functions are required to model a given power system. Instead, the CNN learns the topology and mapping between system control variables and system state variables via feature extraction from existing power flow results. Once the CNN is equipped with the knowledge of power flow calculation, it can be directly adapted to new operation conditions to obtain power flow results without intensive computation.
