In this paper, an improved hybrid maximum power point tracking (MPPT) method is presented. The proposed hybrid method is a hybrid version of fractional short circuit current (FSCC) and perturb and observe (P&O) MPPT method. The proposed improvement in this paper enables the hybrid MPPT method to detect the dynamic weather conditions more precisely than the previously developed methods. Moreover,...
In this paper, a new algorithm is presented for maximum power point tracking (MPPT) of solar PV array. This method first forecasts the maximum power point (MPP) by using tangents to the power-voltage curve at two end points of an interval and then iteratively converges to the MPP by evaluating whether the true MPP lies on the left or right side of the estimated MPP. The proposed algorithm has the...
This paper presents a single-stage, three-phase four-wire grid tied SPV (Solar Photovoltaic) energy conversion system with a decoupled adaptive neural network based control approach for power quality improvement at AC mains. The proposed solar PV energy conversion system, along with feeding fundamental active power to the grid, is capable of compensating linear and nonlinear loads with MPPT (Maximum...
This paper presents a two stage, three-phase grid interfaced SPV (Solar Photovoltaic) energy conversion system with an ANF (Adaptive Notch Filter) based control algorithm. The proposed SPV system is a multi-function grid-interfaced solar PV energy conversion system, which along with conversion of dc-power from SPV to AC mains, is capable of reactive power compensation, harmonics current elimination...
A 4-leg VSC (Voltage Source Converter) based SPV (Solar Photovoltaic) power generating system is integrated to a 4-wire distribution system using MISCT (Modified Instantaneous Symmetrical Component Theory) based control algorithm. This MISCT is used to estimate reference currents to control 4-leg VSC. The control algorithm is used to balance the loads and to improve the power factor of ac mains. The...
