Abstract

The advent of renewable energy, especially in the distributed energy form, have brought many economical benefits to the end user alongside certain key technical challenges to the very utilities they integrate to. The commonest of these issues is the voltage rise at the point of common coupling (PCC) which is being studied in this paper via CYMDIST simulation cases, wherein the presence of a voltage regulator or OLTC device at a predefined node location upstream of the solar PV integration node, helps to recover the voltage profile of the last mile feeder section back within the tolerance range. Cases include, with and without the action of the regulator, all possible modes of operation of solar PV inverter viz. voltage controlled or power factor controlled, although the latter case is experimental only, and not standardized through any grid code amendment till date, at least for India. However all cases clearly demonstrate the well documented voltage variation phenomena due to distribution generation integration.
