This paper reports on the results of using photovoltaic (PV) generation to provide grid support to electric distribution and transmission lines. the analytical methods presented in this paper have been developed to incorporate existing feeder rating methodologies, PV output data and a new evaluation protocol that assesses the effective load‐carrying capability of targeted PV in a grid‐support application. Research results were validated using the Photovoltaic for Utility Scale Applications (PVUSA) 500‐kW Kerman project. Findings indicate that targeted PV generation can reduce summer peaking distribution‐feeder line temperatures, which enables engineers to increase the effective capacity of distribution feeders under standard planning conditions. Evaluating specific feeder conditions with measured PV system output under standard planning conditions indicates PV full load‐carrying capability for the test case area for a PV output of up to 2 MW. For the line under investigation, the maximum allowable load increase is not expected to exceed 40% of the line capacity. the evaluation methodology, while applied to a specific line on a specific feeder, was designed to apply to a diverse set of lines and feeders under varying conditions.
