OpenDSS-based Harmonic Power Flow Analysis for Power Systems with Passive Power Filters

The open distribution system simulator (OpenDSS) is open-source software developed by the Electric Power Research Institute (EPRI) in United States for analyzing systems. OpenDSS primarily used systems fundamental power flow (FPF) and harmonic (HPF). Single-tune high-order filters are generally combined to achieve a better filtering performance practical analysis applications. However, requires filter models. This hinders simulation of comprehensive reliable results. Moreover, HPF calculation errors occur when shunt components exhibit resonance. paper proposes passive models based on injected current technique compensate deficiency OpenDSS. Furthermore, proposed method can effectively prevent parallel resonance errors. results higher accuracy practicability (PPFs)
