The odyssey of monitoring distribution networks

The operation of a power network requires accurate monitoring of its state: bus voltages, line currents, consumption, and generation. This is especially relevant in transmission networks where volatile and distributed generation and consumption cause bidirectional power flow and voltage drops. Therefore, State Estimation (SE) [1] is used to estimate the bus voltage phasors using the…

Forecasting in the electrical grid

[latexpage] A. Uncertainty in the electrical grid In today's electrical grid, as the integration of renewable energy sources (RES) in the grid increases, the uncertainty in the available generation also rises. In particular, the larger the share of RES in the grid, the more dependent is the electricity generation on weather conditions, and in turn,…
