Development of a dynamic model of solar farm and its impact on weak power system

Abstract

This paper presents a comprehensive simulation study to show the adequacy of two solar farm models for small signal stability analysis. Simulation study is carried out by considering solar farm as single-and multi-generator equivalents for both models. The simulation results are presented for a small interconnected system by considering different short circuit ratios (SCR). Both Solar farm models, single-generator and multiple-generator equivalents provide the same results for small signal stability studies for different scenarios.
