What are the different MPPT algorithms?

The most common applied conventional MPPT methods are perturb and observe (P&O) [25, 26], incremental conductance (INC) [27, 28], parasitic capacitance (PC) [29, 30], constant voltage [31, 32], and constant current [33, 34]. These techniques suffer from many shortcomings, they are not capable to work under PSCs.

How does P&O algorithm work?

Perturb and observe algorithm (P&O) In this technique, a minor perturbation is introduced to, cause the power variation of the PV module. The PV output power is periodically measured and compared with the previous power. If the output power increases, the same process is continued otherwise perturbation is reversed.

What is the motivation for MPPT?

The motivation behind developing the various maximum power point tracking techniques was to increase the efficiency of the PV system at power stage i.e. an improvement in power efficiency. By considering this factor, different MPPT methods were proposed by the researchers.

How does MPPT controller work?

MPPT checks output of PV module, compares it to battery voltage then fixes what is the best power that PV module can produce to charge the battery and converts it to the best voltage to get maximum current into battery. It can also supply power to a DC load, which is connected directly to the battery.

What is MPPT voltage?

The MPPT utilizes whole module power by dictating the voltage of the battery charging state. The charge controller keeps the voltage and current at an optimized level where the modules deliver the most juice.

What is P&O in MPPT?

Perturb and observe algorithm (P&O) Typically, P&O method is used for tracking the MPP. In this technique, a minor perturbation is introduced to, cause the power variation of the PV module. The PV output power is periodically measured and compared with the previous power.

Why is MPPT important?

MPPT is a significant advancement in the solar energy industry because it boosts energy yield from PV cells and system reliability. MPPT algorithms are used in grid-tied inverters and batteries and adjust the current voltage.

How is MPPT calculated?

You take the total watts of the solar array divided by the voltage of the battery bank. That will give you the output current of the charge controller. For example, a 1000W solar array รท 24V battery bank = 41.6A. The rating of the charge controller should be at least 40A.

What are the advantages of MPPT?

The benefits of MPPT are as follows: The MPPT controller allows a panel array to be of higher voltage than the battery bank. This is relevant for areas with low irradiation or during winter with fewer hours of sunlight. They provide an increase in charging efficiency up to 30% compared to PWM.

What is perturb and observe method in MPPT?

The proposed Perturb and Observe algorithm is the modification in the conventional algorithm that confines the search space of the algorithm reducing the complexity and improving the performance of the conventional algorithm under uniform and varying weather conditions.
