[IEEE 2017 14th IEEE India Council International Conference (INDICON) - Roorkee (2017.12.15-2017.12.17)] 2017 14th IEEE India Council International Conference (INDICON) - A Correntropy Based Control Algorithm for a Single-Phase Double Stage Grid Integrated Solar PV System
摘要: This paper presents the implementation of a double stage solar photovoltaic (PV) single phase grid connected system using correntropy based control algorithm. This algorithm helps to obtain sinusoidal grid currents even in the presence of nonlinear loads connected at PCC (Point Of Common Coupling), thus improving the power quality of the system. It has almost no steady state error as well as strong filtering ability. The proposed system is configured using a solar PV array, a single phase grid, a voltage source converter (VSC), a DC link capacitor, a boost converter, a ripple filter, an interfacing inductor and the nonlinear loads. The boost converter extracts maximum power from the solar PV array using the drift free MPPT (Maximum Power Point Tracking) method. A prototype is developed to affirm the system performance by testing it under various conditions. The grid conditions of the system obtained after the application of this control strategy conforms well to the harmonic standard IEEE 519.

A Multifunctional Single Phase Grid Integrated Residential Solar PV Systems based on LQR Control
摘要: This paper presents a multifunctional single-stage residential photovoltaic power supply based on Linear Quadratic Regulator. The system makes use of a single phase power converter connected to the grid through an LCL filter. A robust LQRI controller is designed to incorporate added functions such as power line conditioner, active power regulator, and voltage stabilizer. The perturb and observe (P&O) algorithm is used to generate the reference signal for the fluctuating DC bus voltage as well as to extract the maximum power from the solar panels. Full modeling of the converter in the D-Q reference frame is presented. A Linear Quadratic Regulator with added Integral action (LQRI) is designed to achieve optimal multi-functionality operation of the residential power supply. Simulation and experimental results confirm the expected performance of the proposed controller for insolation and load variations.

Solar PV Powered-Sensorless BLDC Motor Driven Water Pump
摘要: This paper deals with a position sensorless brushless DC (BLDC) motor driven-solar photovoltaic (PV) fed water pump. A technique based on the back-EMF (Electromotive Force) zero crossing, is proposed for sensorless operation of the BLDC motor. The back-EMF is derived from the difference of line voltages. Thus, a requirement of neutral potential is eliminated. In addition, the proposed drive avoids the use of phase current sensors. The speed is automatically adjusted according the available peak power from the PV array. The devices of voltage source inverter (VSI), used to feed the BLDC motor-pump, are switched at fundamental frequency. This leads to the minimized switching losses. The responses of PV fed pumping system with the proposed drive, are observed under various operating conditions. The suitability of proposed topology is demonstrated through the hardware implementation.

[IEEE 2018 53rd International Universities Power Engineering Conference (UPEC) - Glasgow, United Kingdom (2018.9.4-2018.9.7)] 2018 53rd International Universities Power Engineering Conference (UPEC) - A Modified P&O-MPPT based on Pythagorean Theorem and CV-MPPT for PV Systems
摘要: Maximum power point tracking MPPT techniques are a crucial part in photovoltaic PV system design to maximise the output power of a PV array which depends on weather conditions. Although several techniques have been developed, Perturb and Observe P&O is widely used for MPPT due to its low cost and simple implementation. However, the main drawbacks of this method are a low converging time, high oscillation around the maximum power point, and drift problem associated with changing irradiance rapidly. In this paper, a modified P&O-MPPT based on Pythagorean theorem and constant voltage CV-MPPT is presented. To assess this modification, conventional and modified P&O methods are simulated by a MATLAB-SIMULINK. Simulation results demonstrate that the modified P&O-MPTT has a highly effective to solve the problem of conventional P&O-MPPT.

Dual-Input Single-Resonant Tank LLC Converter with Phase Shift Control for PV Applications
摘要: This paper proposes a dual-input LLC resonant converter that interfaces with two PV panels. The topology is a dual half-bridge LLC circuit with four active switches. This topology allows the two sources to share the same resonant tank for transferring energy to the load without the need for additional circuit components. A phase-shift pulse width modulation independent maximum power point tracking (MPPT) for each PV panel. Independent MPPT is achieved by varying the PWM phase shift of each source. Zero-voltage-switching (ZVS) is realized in all switches over the entire range of source voltage and load conditions. In addition, voltage stress across switches does not exceed the input PV voltage. A 500-W prototype was built to demonstrate the performance of the proposed topology. The input voltage range was selected between 25 V to 50 V with an output voltage regulated at 220 V DC. Experimental results show that the proposed converter can achieve the peak efficiency of 95.8% while maintaining a wide input voltage range and implementing MPPT for each PV panel.

摘要: This paper compares three techniques for maximum power point tracking of a solar PV; namely, Fuzzy logic, perturb and observe (P&O) and increment conductance method (IC). It is shown that the Fuzzy control technique gives a better and more reliable performance than the conventional methods. It can track the maximum power point (MPP) faster and minimize the power oscillations around the MPP. The paper also describes how the P&O algorithm gets lost in tracking the MPP under rapid varying irradiance and how the IC is unstable at low irradiance.

Optimal Hybrid Neuro-fuzzy Based Controller Using MOGA for Photovoltaic (PV) Battery Charging System
摘要: This paper proposes an optimal hybrid neuro-fuzzy/fuzzy controller based on maximum power point tracking (MPPT) technique and voltage regulation for photovoltaic lead-acid battery charging system through the constant current and constant voltage (CC-CV) charge, denoted by NFC-CC/FLC-CV. The parameter optimization of NFC and FLC, including rule selection, based on multi-objective genetic algorithm (MOGA) is applied to the NFC-CC design to improve the tracking accuracy while reducing complexity. By means of genetic optimization, the number of fuzzy rules can be greatly reduced by 50%. In addition, GA is applied to the FLC-CV design to increase voltage regulation (VR) accuracy. After satisfying the stability condition through the solutions determined by MOGA and GA, the performances of controllers under rapidly-changing weather are evaluated tradeoff by several creteria, including transient response, stabilized accuracy, charging time, and energy utilization and charging ef?ciency. As results, the proposed controller outperforms the other existing controllers with the fastest rise time without overshoot, the highest MPPT and VR accuracy with negligible oscillations, a 12-23% reduction in charging time, and an increase of 5-15% and 1-6% in energy utilization and charging ef?ciency. Furthermore, it provides superior results in terms of computational complexity by achieving the minimum number of multiplications and system parameters, and high reliability with the lowest Akaike information criterion (AIC).

Developed and STM implementation of modified P&O MPPT technique for a PV system over sun
摘要: The non-linearity of photovoltaic systems and the change in maximum power point with a level of insolation and temperature complicates the tracking of the maximum power point. Several maximum power point tracker methods have been proposed and implemented in literature. The paper studies a modified perturb and observe (P&O) approach for a photovoltaic system in order to extract the maximum power point with more precision, fast speed and avoid the problems caused by the classic P&O method under the change of climatic conditions. This work is tested with a resistive load powered by a photovoltaic generator via a DC/DC converter. These methods are implemented with STM32F4 microcontroller running environment MATLAB/SIMULINK, using a computer incorporating a card DS1104 for visualization. The simulations and experimental results show that the proposed algorithm offers a fast response with smaller stationary oscillations compared to conventional methods.
