"Grid State Estimation in Swarm Grids",
Masterprojekt TH-Köln, 14.3.2023

Traditional grid state estimation in low voltage grids is performed centralized by Distribution System Operators. In order to increase the robustness of the power systems and user autonomy, this paper proposes a Swarm Grid based approach for state estimation.
Data is optionally prepared by exchanging values between current and voltage vector, described as exchange operator using Principal Pivot Transform. A combination of weighted, constrained and bounded least squares algorithm is proposed as state estimation algorithm. Additionally, worst-case assumptions are presented which help to achieve reasonable estimates of the unknown grid voltages and currents used for the decentralized grid control.
