A Method to Select Effective Measurement Device Placement for Area Inertia Estimation

The high penetration of renewable energy sources raises concerns about decreasing power system inertia. To prepare for system separation events, continuous area-based inertia monitoring is desirable. To achieve continuous monitoring of area inertia, it is essential to accurately estimate area inertia using a limited number of measurement devices. In this paper, we propose a method to select effective measurement device placement for area inertia estimation. The effectiveness of the method is also verified by simulations using the IEEJ WEST 30-machine system model.
