Optimal operating point tracking in a stand-alone PV system using particle swarm optimisation
In this paper, particle swarm optimisation (PSO) technique is employed to determine the optimal operating point of a photovoltaic module used in a stand-alone PV system. The PSO algorithm identifies the maximum power point by determining the array voltage at maximum point (VMPP). This value is utilised as a reference value to a voltage controller to adjust the duty cycle of a boost converter such ...

A modern MPPT control algorithm based on α–MPP pass–through detection and β–acceleration mechanism
A modern maximum power point tracking (MPPT) method based on the incremental conductance (IncCond) control algorithm is discussed. This method features a variable step iteration of duty ratio to get over the trade–off between dynamic performance and steady state oscillation around maximum power point (MPP). Moreover, in the aim to get an excellent precision and a swift response independently of ...

Global maximum power point tracking for partially shaded PV arrays using particle swarm optimisation
This paper introduces a global maximum power point tracking (GMPPT) method for a group of photovoltaic modules connected in series and operating under different levels of solar irradiation using particle swarm optimisation technique. Partially shaded PV modules produce several local maxima power points, which makes the tracking of the global maximum power a difficult task. Most of traditional ...

How solar is transforming an old mining town
You hike over the crest of the hill and there it is: 96 sun-tracking solar masts, each with 42 solar modules — 4,032 modules in all — perched on the side of a hill with the beautiful Rocky Mountains in the background. It’s called the SunMine project and it’s all part of the reinvention of Kimberley, B.C., from mining town to a clean tech, tourism town of the future. ...

Design of single–stage three–phase grid–connected photovoltaic system with MPPT and reactive power compensation control
This paper proposes a single stage three–phase grid–connected photovoltaic (PV) system topology, it being simpler and more efficient. This includes the modelling of PV module and the power conditioning unit interfacing the PV to the utility grid with proper power flow control. The output of the PV panel is connected to the DC–side of the voltage source inverter for interfacing to the grid. The ...
