The modern power system is a complex network which contains of numerous generators, transmission lines, loads and transformers etc. There has been exponential increase in the power demand over the last few decades, transmission lines are loaded more than was planned. With the increased loading of long transmission lines, the problem of transient stability, after a major fault becomes a transmission limiting factor. This leads to FACTs devices being installed in the system. The scarcity of power can be met by using renewable sources like Solar Energy, Wind energy etc. The Solar Energy systems also called PV system can be used in isolated or grid connected mode. PV system has numerous benefits and its use has been increasing in recent years. Beside electricity shortage, a more vulnerable issue in modern power system is related to quality of power delivered. A good quality of power ensures smooth operations of electrical utilities. Harmonic distortion in the grid is produced by non-linear loads connected to grid. This reduces the power quality in the system.

“…Among all renewable energy sources, solar energy is currently a favorable choice in many countries and regions. The photovoltaic (PV) generation system has widely been applied to either standalone or grid-connected power systems [1][2][3][4][5], e.g., space satellites, PV plants, solar vehicles, solarwater pumping systems, etc. It is an essential problem to improve the working efficiency of PV generation systems, which necessitates the design of a more efficient and accurate maximum power point tracking (MPPT) algorithm.…”

This paper proposes a novel high-efficiency generation technique for photovoltaic (PV) system, named maximum power point capturing (MPPC) technique. This is an aperiodic perturbation MPPC technique compared to the conventional periodic perturbation maximum power point tracking technique. Firstly, under a closed-loop circuit and an open-loop circuit, the complete I-V curves and P-V curves are defined. Secondly, the proposed MPPC technique is based on the complete I-V curves and a practical model of solar PV systems. The proposed method realizes that maximum power point (MPP) is captured online, and its control strategy is designed to set a steady operating area around MPP. The duty cycle keeps constant when the operating point is within the steady operating area, i.e., aperiodic perturbation, and when the operating point is outside the steady operating area, MPPC is triggered to capture a new MPP with an updated steady operating area. Simulation results demonstrate that no oscillations exist in steady-state; dynamic performances are improved; and only two perturbations are required to capture the new MPP. Using the proposed MPPC method, low voltage ride through and high voltage ride through can be prevented.

“…Analytic photovoltaic module modeling with the parameters provided by PV module manufacturer is critical for PV plant sizing [1,2], simulation [3], testing [4], PV plant monitoring [5,6], dispatching [7], and energy management [8]. A very popular PV module model introduced by Borowy & Salameh [2] named 2C model proposed in this paper, has been heavily cited by 229 papers from Google and 66 papers from IEEE-Xplore database, with no derivation process.…”

A popular explicit analytic Borowy 2C PV module model is proposed for power generation prediction. The maximum power point and the open-circuit point which are calculated in this model cannot be equal to the data given by manufacturers under standard test condition (STC). The derivation of this model has never been mentioned in any literatures. The parameter forms of 2C model in this paper are more simplified, and the model is decomposed into a STC sub-model and an incremental sub-model. The STC model is derived successfully from an ideal single-diode circuit model. Relative error estimations are developed to do the conformity error measurements. The analysis results showed that though the biases at those critical points are very small, the conformity will depend on both of the two ratio values I m /I sc and V m /V oc , which can be used to verify whether 2C model is applicable for the PV module produced by a particular manufacturer.
