“…MPPT algorithms are numerous [4]. The Constant Voltage (CV) approach [5,6], beta method [7,8], Ripple Correlation method [9], Incremental conductance method, and Perturb and Observe method [10][11][12] are some of the more often utilised and effective MPPT techniques. CV has the simplest algorithm among the MPPTs, making it the easiest to implement.…”

This paper involves an incremental conductance Maximum Power Point Tracking (MPPT) algorithm for solar panel output. MPPT, or Maximum Power Point Tracking, is a charge controller algorithm that is used to extract the maximum available power from a PV module under particular conditions. Maximum power point (or peak power voltage) refers to the voltage at which a PV module may output the most power. Maximum power is affected by solar radiation, ambient temperature, and the temperature of the solar cell. The output of the solar PV array is connected to DC-DC boost converter. To verify the effectiveness of the algorithm, the MATLAB/SIMULINK results are presented.

“…Moving clouds can cause great inefficiency in large photovoltaics power plant due to PSC [3]. The conventional P&O (Perturb and Observe) algorithm can only track maximum power when the operation of MPPT is under UIC [4]. But when an MPPT operates under PSCs the P&O algorithm fails to track the maximum power [5].…”

The operation of PV systems can experience uniform (UIC) and partial insolation (PSC) that depends on its environment. Many MPPT algorithm has been proposed in literature such as P&O, and many metaheuristics algorithm such as PSO and GWO. Those algorithm only work at a certain environmental condition. The P&O algorithm only work at UIC but fail to track maximum power at PSC hence reducing efficiency of MPPT system when it is experiencing UIC and PSC. The GWO algorithm can track maximum power at PSC but when the change of insolation to UIC can shift power output below maximum power hence reducing efficiency of MPPT system. In this paper another method is proposed by implementing the result of GWO to the input of the P&O algorithm subsequently the GWO is reset periodically to search a new maximum power point to anticipate any environmental changes. This new method is called a GWO-P&O algorithm. Simulation results show that the GWO-P&O algorithm yields better efficiency compared to the GWO or the P&O algorithm in case the modules of PV array experiencing UIC and PSCs. Simulation is done using MATLAB/SIMULINK software.

“…Energy harvesters can also help to prolong the battery life of given electronic systems. EHs are increasinghly becoming an integral part of many electronic applications, mainly the sensor systems [1]. The stand-alone harvesters that work without the support and management circuit, rarely deliver the output power with the maximum efficiency.…”

This paper presents design of a Maximum Power Point Tracking (MPPT) circuit and its functionality for tuning the maximum power transfer from an energy harvester (EH) unit. Simple and practical "Perturb and Observe" (P&O) algorithm is investigated and implemented. We describe the circuit functionality and the improvements that have been introduced to the original algorithm. The proposed MPPT design is divided into three main blocks. The output signal is being generated by the PWM or PFM block. The tracking speed has been enhanced by implementing a variable step size in the "Tracking Block". Finally, the overall power consumption of the MPPT circuit itself is controlled by the "Power Management Block", which manages delivering the clock signal to the rest of the circuit. The RTL code of the proposed MPPT has been created in Verilog, synthesized and placed-and-routed in a general purpose 130 nm CMOS technology.
