About this Research Topic
This Research Topic has been realized in collaboration with Dr. Zhifang Yang, Assistant Professor at Chongqing University in China.
Traditional power system analysis is conducted based on analytical models of power grids and electrical elements. However, this model-driven approach occasionally encounters difficulties facing the increasing scale of the model and unclear power system topology and demands. For example, traditional probabilistic analysis involves repeated power flow calculations and optimization solutions over multiple (tens of thousands) instances in time. Such repeated computation becomes a bottleneck for practical and fast applications in power industries given the increase in sub-system and device complexity. Moreover, in certain regimes like distribution power networks, new optimization problems are being proposed which need to incorporate incomplete information about system state, topology and control logic. In either instance, repeated model-driven power system analysis would be difficult to scale up.
The data-driven approach provides a new way to solve these challenges. While model-driven approaches consider the power system to be a “white box”, data-driven approaches can be either “grey box” or even “black box”. Using partial system knowledge and power flow physics are instances of “grey box”, and plug and play based operations are instances of “black box”. Data-driven methods have the potential to efficiently combine the extensive measured data with prior knowledge and historical data for actionable outputs in various scenarios. On one hand, this can lead to novel ways for event detection, localization and modeling in power grids. On the other, it can lead to reduced search spaces and good warm start for improved convergence of traditional optimization problems in power grids.
