Harmonic performance of heat‐pumps

Abstract

Reverse cycle air‐source heat‐pumps are an increasingly significant load in New Zealand and in many other countries. This has raised concern over the possible impact wide‐spread use of heat‐pumps will have on the grid. To analyse this impact, models are needed to enable system studies to be performed. In this paper, the results from testing six heat‐pumps are presented. The heat‐pumps are classified based on observed performance. Moreover, the heat‐pumps’ designs are investigated and power system computer aided design/electromagnetic transient program for DC (PSCAD/EMTDC) models developed and verified against the measured performance.
