Description: The use of solar energy as a source for pumping water is one of the promising areas in the photovoltaic (PV) application. The energy of photovoltaic pumping systems (PVPS) can be widely improved by employing an MPPT algorithm. This will lead consequently to maximize the electrical motor speed of the system.

The influence of the algorithm parameters on system behavior is investigated and compared with the traditional (INC) method. The studied system consists of a PV panel, a DC-DC boost converter, and a PMDC motor-pump. The simulation of the system by MATLAB-SIMULINK is carried out.

Description: simulation and hardware implementation
of incremental conductance (IncCond) maximum
power point tracking (MPPT) used in solar array power systems
with direct control method. The main difference of the proposed
system to existing MPPT systems includes elimination of the
proportional–integral control loop and investigation of the effect of
simplifying the control circuit. Contributions are made in several
aspects of the whole system, including converter design, system
simulation, controller programming, and experimental setup. The
resultant system is capable of tracking MPPs accurately and
rapidly without steady-state oscillation, and also, its dynamic performance
is satisfactory. The IncCond algorithm is used to track
MPPs because it performs precise control under rapidly changing
atmospheric conditions. MATLAB and Simulink were employed
for simulation studies, and Code Composer Studio v3.1 was used
to program a TMS320F2812 digital signal processor. The p Platform: |
