Analysis of Auxiliary Energy consumption in Utility scale Solar PV Power plant

Abstract

The main concern of this paper is to investigate average daily auxiliary consumption of PV plants of various capacity & to obtain an inter-relation between them. Further to investigate percentage contribution of each component in order to get consumption of transformers and inverters separately. In addition, inverters & transformers used in various plants are not of same capacity and same manufacturer. Hence the study will figure out an inverter & transformer which has least per unit consumption & a PV plant designer can have an idea while selection of inverters & transformers for a given size of plant. Overall this study helps us to maximize the export energy & minimize the aux consumption within plant by right selection of equipment’s for PV plant during design stage.
