“…Since the PV is in parallel connection with the 3L-VSC while starting to generate power at transition point, intuitively, voltage drop would be experienced. This voltage sag would continue, and the dc loads operation will remain undesirable until the PV voltage rises just above the lower voltage limit of the set condition in (8).…”

“…In this case, it is about 771 milliseconds and it is after this time that the voltage of the PV rises above Vt_L, and continuous sampling of PV voltage for maximum power point tracking is re-initiated. More so, the carefully chosen numerical value of Vt_L (485V) which is made to be greater than the lower limit 0.94Vdc_linkn of the set condition in (8) is an added feature of the proposed algorithm.…”

“…Among the MPPT techniques, Perturb and Observe MPPT (P&O MPPT) algorithm is popularly used due to its cost effectiveness and simplicity. Many studies [5][6][7][8][9] have been carried out with employment of different versions of P&O MPPT techniques in the areas of efficiency improvement and reliability enhancement of PV system connected to either loads or main grid via power electronics devices such as ac-dc converter and dc-dc converter at low voltage operation. In [5], modified P & O MPPT techniques was proposed where sampling oscillation around the maximum power point (MPP) was avoided by monitoring changes in irradiance during partial shaded conditions.…”

“…Grey Wolf-based P & O MPPT algorithm was employed in [7] to mitigate the undermining effect of swift variation of insolation and partial shading on the power optimisation of PV. However, in [8], the version of P & O MPPT algorithm employed as PV power optimser was based on self-predictive and decisive. This version is employed to strengthen the weaknesses of some modified P & O MPPT algorithms used in various solar PV systems.…”

“…Comparatively analysis of the results obtained from the two algorithms is done in next section.IV. DISCUSSION OF RESULTSInvestigation revealed that the violation of the set conditions in (6)-(8) by the huge voltage sag as observed in both the dc link voltage across R3 (seefigure 5) and voltage across R1 & R2 (seefigure 6) is technically linked to abrupt change in the high reference voltage of the dc link PI controller (Vdc Regulator) during zero irradiance (500V) to low voltage of the PV power optimizer at the transition point. The low voltage of the PV power optimizer at this point corresponds to M V ) of the PV just above zero irradiance.…”

This paper presents a limit-based approach in improving transient performance of tank-circuited 3-Pole PV Based DC Microgrid (3-PPDM) during zero to non-zero insolation transition of the solar irradiance profile. This approach is necessitated due to the transient behavior of the microgrid during the above-mentioned transition that results into huge voltage sag which appears to violate the conditions set for desirable operation of the dc loads. The tank-circuited 3-PPDM is conceived to mimic, under set conditions, operational feature of grid-connected three-phase ac microgrid where transformer is not required at distribution level for the provision of different voltage levels (phase and line) operation within the ac microgrid. 3-PPDM is developed with PV Based DC Microgrid connected to ac grid via single stage dc link and 3-Level Voltage Source Converter (3L-VSC). The dc loads are directly connected to the dc link and operated at high and low voltage levels without the employment of dc-dc converters. These voltage levels are established via the support of the three poles created by two serially connected centre-tapped capacitors meant primarily for improving the harmonic performance of the 3L-VSC. The observed huge voltage sag is technically linked to abrupt change in the high dc link reference voltage of the dc link PI controller during zero irradiance to low voltage of the PV power optimizer at the transition point. Subsequently, a limit-based perturb and observe maximum power point tracking (P&O MPPT) technique was employed as corrective measure. The concept of the technique is to determine the transition point and assign suitable predetermined value that is within the technical constraint of the microgrid as the reference voltage of the dc link. The simulation results of this approach prove the efficacy of the techniques as the set conditions are successfully met within considerable time, leading to an improvement in the transient performance of the microgrid.

Summary This article intends to present a compendious review to extract maximum power in solar photovoltaic (PV) systems under varying environmental conditions and partial shading conditions by enumerating various circuit‐based topologies and different state‐of‐the‐art maximum power point techniques (MPPT). Partial shading reduces the overall efficiency of the PV system; therefore techniques that are dealing with partial shading play an important part in the power conditioning unit of all PV system connected to the stand‐alone mode or grid mode. Various circuit‐based topologies and various algorithms have been broadly discussed till date. As every algorithm is associated with its own merits and demerit, hence an extensive literature survey is required while planning for PV generating station under normal and partial shading condition. In this article, a comprehensive review of shading mitigation using different topologies has been done. The article on shading mitigation is broadly divided into two major groups. The first group includes all major circuit‐based topologies and the second group includes MPPT based techniques, which has been further classified into modified conventional techniques, soft computing techniques, and hybrid techniques. This comprehensive review presents an assessment of all techniques according to parameters like converter used, tracking speed, complexity, efficiency, number of sensors under partial shading condition would certainly provide a single platform to carry forward their research in solar PV application.

The direct and indirect control methods are commonly used for maximum power point tracker (MPPT) of photovoltaic (PV) systems. Due to the absence of the literature that assess their performance in a comprehensive way, this work attempts to analyze the effectiveness of both control methods for the perturb and observe (P&O) MPPT algorithm. The MATLAB/Simulink simulation is verified experimentally using a PV array simulator and the dSPACE DS1104 DSP board driving a buck-boost converter. The results show that the indirect method exhibits lower steady-state oscillation and is less sensitive to rapid irradiance change and load variations. It increases the steady-state efficiency by 1.6%. Furthermore, under irradiance and load step changes, the transient efficiency increases by 29% and 30%, respectively. Based on these findings, it is envisaged that the indirect method is more suitable to be used as the controller in conjunction with the MPPT algorithm.
