Harmonics: Not a Problem Unless They Become One Harmonics in modern power systems are now considered “the new normal” due to the widespread use of non-linear loads. While harmonics can lead to issues such as overheating, overloads, and resonance, they don’t always pose immediate problems. The key is understanding when harmonics are actually causing harm. When Should You Ac...
Abstract This article introduces a method for short-term forecasting of photovoltaic (PV) generation. The proposed method falls within the category of physical methods and relies on numerical weather forecasts. Forecasting was achieved by utilizing a PV source model in the OpenDSS software. The calculated results were compared to actual measurements taken from operational PV micro-installations. A...
