Solar irradiance estimation and optimum power region localization in PV energy systems under partial shaded condition

Trio-PV Monitor: A Smart IoT-Based Instrument for Continuous and Reliable Monitoring of Solar PV Installations

“…Operationally, the performance of a PV system is contingent on the location and the condition of PV panels. Particularly, weather conditions have an inherent influence on the operation of these systems [7]. As a consequence, close monitoring and performance evaluation with respect to environmental changes can help in the enhancement of their performance.…”

Towards a Simple and Efficient Implementation of Solar Photovoltaic Emulator: An Explicit PV Model Based Approach

“…The effective implementation of these systems requires proper validation through testing. However, controlled testing is still a challenging exercise owing to the spontaneous variations in environmental conditions [6,7]. Recently, a photovoltaic emulator (PVE) has been suggested as a potential instrument for effective and controlled testing of PV systems.…”

A Novel MPPT-Based Solar Irradiance Estimator: Integration of a Hybrid Incremental Conductance Integral Backstepping Algorithm for PV Systems with Experimental Validation

“…Monitoring solar irradiance is not only important for PV systems, as the supervised parameter intersects largely with many interdisciplinary fields, including agriculture and environmental science [6]. When it comes to measurement, the Pyranometer is considered one of the most commonly used instruments for directly measuring solar irradiance [7]. Pyranometers are not cost-effective, have several sensors, and must be positioned in the direction of their corresponding panels [8].…”

“…Originally, the authors proposed conventional MPPT algorithms, such as P&O, to drive the PV system at the MPP. Recent progress in MPPT research has shown that conventional algorithms present problems, such as oscillations at the maximum power point and a tradeoff between dynamic response and steady-state oscillations [3,5,7]. These problems are inherent in conventional MPPT algorithms and will consequently impact the performance of the MPPT-based estimator.…”
