Net load forecasts for solar-integrated operational grid feeders

A Petri-net Model for Operational Cycle in SCADA Systems

Supervisory control and data acquisition (SCADA) system monitors and controls industrial processes in critical infrastructures (CIs) and plays the vital role in maintaining the reliability of CIs such as power, oil, and gas system. In fact, SCADA system refers to the set of control process, which measures and monitors sensors in remote substations from a control center. These sensors usually ha...

Validation of Short and Medium Term Operational Solar Radiation Forecasts in the Us

This paper presents an initial validation of a solar radiation service that provides historical, as well as up-to-the-moment solar resource data from satellites, short-term forecasts from cloud motion analysis, and medium term forecasts (up to seven days ahead) from numerical weather prediction models [1]. Forecasts are validated for several, climatically distinct regions of the US, investigati...

A Comparative Verification of Forecasts from Two Operational Solar Wind Models (postprint)

Grid Integrated Solar Photovoltaic System Using Multi Level Inverter

ABSTRACT: In any PV based system, the inverter is a critical component responsible for the control of electricity flow between the dc source, and loads or grid. This paper presents a solar PV generation system integrated to the grid. The results of matlab modeling of the system detail the comparative operation of inverter topologies which are the conventional two level inverters and multilevel ...

Probabilistic Forecasts of Solar Insolation

Meteorological forecasts of incident solar radiation are valuable for solar resource owners and others. Most previously described forecast methods provide a single predicted value. However, a well-calibrated forecast probability distribution is more useful in that it could be used to make optimum decisions under any decision rule. We demonstrate methods of constructing and evaluating probabilis...
