Awareness of Converter Integrated Distributed Energy Resources(CIDER) in Distribution Networks Based on Non-Fundamental Apparent Power Tracing

Installed capacity of converter integrated distributed energy resources (CIDER), such as wind power and photovoltaic (PV), has increased rapidly, leading to the increasingly serious problem of harmonics in the power system. To effectively monitor the integration of existing distributed power sources into the distribution network and quantify their impact, it is necessary to trace the sources of distributed power with random injections and quantify the influence of each distributed power source at the point of common coupling (PCC). This paper would decompose the power injection data from CIDER into fundamental and non-fundamental apparent powers, and the latter part will be used as quantification indicator for the impact of CIDER. A dynamic awareness and power tracing method would used to quantify the impact of each distributed power source at the PCC through multiple CIDER measurements, achieving precise perception of CIDER impacts.
