Optimal operation of certain power loads fed from a photovoltaic generator(PVG)

In this paper, optimal operation of some power loads fed from PVG source is investigated. The optimal operation consists of fulfilling two objectives simultaneously. The first objective consists of matching the maximum power that can be generated by the PVG with the power absorbed by the load. The s econd objective consists of conditioning the current supplying the load whe n the fatter is of AC nature. The first objective is performed by installin g a maximum pourer point tracker between the PVG source and the power load. The trader is a step-up converter controlled by Schmitt trigger controller . The second objective is done via the connection of an, active pouter filt er in parallel with the AC power load. The active power filter target is to take care of all unwanted current harmonics that may penetrate to the AC l oad circuitry. A second Schmitt trigger controller is also used to control the operation of the active power filter. The power loads considered in this study are of two types: (1) DC loads: pu re resistive and DC motor; (2) AG load: capacitor run single-phase inductio n motor. The performance evaluation of all proposed configurations are tabu lated via the use of EMTP computer program. The results obtained prove the satisfaction of both objectives of the investigation.
