Abstract

Solar and renewable plants are increasingly being added to national grids. One technical drawback of renewable generators is that they tend to cause a significant harmonic distortion of the current and voltage waveforms. The harmonic distortions are amplified when the natural resonances of the grid interact with the injected harmonics from the power electronic based PV generation. A sustained harmonic distortion can lead to equipment failure, reduced plant output or a complete plant shutdown. Therefore, it is important to study harmonic interactions and resonance issues using fully detailed EMT models before the commissioning of a renewable plant. This paper outlines important features of modelling solar converters for the use of harmonic and resonance studies.

Abstract

In this paper a methodology for a transition away from a fossil fuel dependency to clean energy in remote communities in northern Canada is presented. Both technical and non-technical obstacles associated with such a transition to clean energy are outlined. A proposal on how to possibly overcome these obstacles is also presented. The technical aspect of this work includes a case study on one of the communities in northern Manitoba, Canada. The case study is supported by simulations, using the software tool PSCADTM/EMTDCTM. The simulation result illustrates how the control system coordinates various parts of a microgrid and reduces annual diesel consumption.
