TLDR
In this article, a time step simulation-based methodology is adopted to determine the optimum mix of outputs from a photovoltaic (PV) and diesel generator set (DG) on the basis of minimum cost of energy in Rs/kWh.Abstract:
A sustainable option in the mandatory use of diesel generator set (DG) is its integration into the solar photo-voltaic system (PV). A major issue, in this integration, is achieving an optimum mix of energy delivered by DG as well as that obtainable from PV. This paper determines the optimum mix of outputs from a PV and the DG on the basis of minimum cost of energy in Rs/kWh. A time step simulation-based methodology is adopted. Results indicate, if 70 % of the annual energy demand is met by DG while remaining 30 % is met by the PV, the cost of energy will be the least at 13.1 Rs/kWh. Sensitivity of the optimum mix is examined in the light of relevant parameters.read more
