“…Authors of [9] propose a globally convergent estimator of the irradiance starting from v, i and T measurements, assuming that the plant operates in MPPT mode and without extending the analysis to the power estimation. Finally, in [10] the reverse model approach is proposed to implement MPPT for a single panel by integrating irradiance measurements from a dedicated pyranometer for the identification phase only.…”

Abstract-In this paper, we propose a model-based filtering strategy to reconstruct the maximum power production of a PV power plant thanks to integrating measurements of the PV cell temperature, system DC voltage and DC current. The filter relies on a reversed physical model of the targeted PV system and enables to, first, determine analytically the irradiance incident to the panels, and, second, estimate the DC power production as if the plant was operating in maximum power point tracking (MPPT) mode. We present how the approach can be used to reconstruct the maximum power value starting from a generic operating point. As an application, we show that the proposed strategy can improve time series-based solar power forecasting techniques, in particular when the production of the PV system is curtailed and thus the measured power does not correspond to the maximum available.

“…Due to simplicity and robust nature, PO and curve fitting techniques are widely used. MPPT techniques and algorithms have gained attention of power system researchers [70][71][72][73][74][75][76][77][78][79][80][81][82][83][84][85][86][87] due to its dominant advantages over conventional techniques. Table 2 shows some commonly used control strategies for PV-MPPT and EUE obtained.…”

Power extension of grid to isolated regions is associated with technical and economical issues. It has encouraged exploration and exploitation of decentralized power generation using renewable energy sources (RES). RES based power generation involves uncertain availability of power source round the clock. This problem has been overcome to certain extent by installing appropriate integrated energy storage unit (ESU). This paper presents technical review of hybrid wind and photovoltaic (PV) generation in standalone mode. Associated components like converters, storage unit, controllers, and optimization techniques affect overall generation. Wind and PV energy are readily available, omnipresent, and expected to contribute major future energy market. It can serve to overcome global warming problem arising due to emissions in fossil fuel based thermal generation units. This paper includes the study of progressive development of standalone renewable generation units based on wind and PV microgrids.

There are mainly two different types of PV performance models in the literature employing either (a) a detailed circuit model [1]- [10] or (b) simple semi-empirical expressions [2]- [6], [11]- [24]. The former approach adopts an electrical equivalent circuit and permits derivation of the entire I-V characteristic.…”

-There are several photovoltaic (PV) performance models in the literature, but most of them either employ complex and tedious calculations or require additional measurements apart from datasheet information. In this paper, a new set of performance equations to evaluate the short circuit (SC) current, open circuit (OC) voltage and maximum power point (MPP) at any operating conditions is introduced. The proposed expressions are simple functions of the irradiance and temperature, while they are generally applicable to any crystalline PV module and require only datasheet information as input data. This is achieved by introducing new formulas to determine the irradiance and temperature coefficients that are not provided in the datasheet, thus avoiding empirical constants or additional measurements. The novelty of the performance equations is their solid theoretical background, as they are in excellent agreement with the singlediode PV model, combined with simple and easy application. The proposed PV model is validated and compared to other methods found in the literature through simulations in MATLAB and outdoor measurements on commercial PV modules. Index TermsIrradiance coefficients of Vmp (dimensionless). . The former approach adopts an electrical equivalent circuit and permits derivation of the entire I-V characteristic. It provides complete information on the system's operation, but generally requires several implementation steps such as: extraction of the model parameters, translation to actual operating conditions, derivation of the characteristic curve etc. On the other hand, the methods that adopt semi-empirical expressions are straightforward and more easy-to-use, evaluating simple explicit equations in a single step. However, they provide specific only information, such as the short circuit (SC) current, the open circuit (OC) voltage and the maximum power point (MPP), rather than the entire characteristic. The latter methods are the focus of this paper.There [12] provide all essential information required for a PV energy yield study: the SC current, the OC voltage and the MPP voltage and current, denoted hereafter as the three key operating points. If these are known for a particular PV system, then all other energy yield parameters are readily derived, such as the maximum power or fill factor (FF).However, the simplicity of the aforementioned models comes at the cost of reduced accuracy, as they either rely on empirical observations or consider questionable assumptions. Specifically, the equations proposed in [11]
