Economical Calculations based on ACS Concept.
Economical calculations of the system are performed after the unit-sizing program has been run.
Three economic metrics are developed to evaluate economics of PV/FC hybrid system which are called Initial Cost of the system (IC), Annualized Cost of System (ACS), and Cost of Electricity (COE). The initial cost of the system is the sum of the products of component cost and its size. Six main components are considered: PV array, Electrolyzer, Compressor, Hydrogen tank, Fuel cell and the other devices. The other devices include controller, inverter and rectifier. The IC can be expressed by the following Equation:-
