Is diesel generator set a sustainable option?

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.

Is a hybrid PV-diesel system better than a diesel generator?

When the PV array costs 150 Rs/Wp, the optimum PV penetration is 20 % and the COE of the system is almost equal to a diesel generator only option. However, when the array is priced at 130 Rs/Wp, a hybrid PV-diesel system offers an advantage at the optimum penetration of 30 %.

Can a diesel generator be removed during the sunshine hours?

If part of the load is during the sunshine hours and rest during the non-sunshine hours, the diesel generator will be required to cater to that portion of load which exists during the non-sunshine hours. On the other hand, if the entire load is only during the sunshine hours, the diesel generator may be eliminated.

Can a photovoltaic array be integrated with a diesel generator?

This paper presents viability of integrating a photovoltaic array with a diesel generator in an off-grid mode without storage. The COE energy in Rs/kWh is a chosen parameter for viability. The PV penetration is the pre-specified fraction of demand to be replaced by the PV array.

Can DG-PV hybrid systems be used without storage?

A limited literature is available on hybrid systems without storage. Annual performance of an existing DG-PV hybrid system catering to a peak load of 75 kW reports wasteful dumping of renewable energy due to lower demand in the sunshine hours and over sizing of the DG set leading to frequent part-load operation (Pelland and Turcotte 2011 ).
