Synthetic/virtual Inertia in Renewable Energy Sourced Grid: A Review

Wind Power Plant’s Synthetic Inertia Estimation Using Extended Kalman Filter

“…Since J can have many values, stability analysis often employs a new constant known as the normalized inertia constant, denoted as H. This approach helps constrain the values to a narrower range, typically between 1 and 10 (p.u.). It is defined as: To date, most authors have presented possible solutions to the potential exploitation of synthetic inertia through block diagrams in the management structure of wind power plants, where works such as [7][8][9][10][11] stand out. It should be noted that, in order to utilize the potential of synthetic inertia, fast measurements from PMU (Phase Measurement Unit) devices are required [12].…”

“…However, the distinction between synthetic inertia and a traditional single generator's moment of inertia can be observed in Figure 1. To date, most authors have presented possible solutions to the potential exploitation of synthetic inertia through block diagrams in the management structure of wind power plants, where works such as [7][8][9][10][11] stand out. It should be noted that, in order to utilize the potential of synthetic inertia, fast measurements from PMU (Phase Measurement Unit) devices are required [12].…”
