This paper proposes the modelling of optimal planning of hybrid systems and economic dispatch of the hybrid system. This paper also deals with three different objective functions: minimization of cost, reduction of CO2 emission and primary energy consumption.
It was seen that the cO2 emission, running cost and primary energy consumption were low compared to conventional energy cost.
