The excursion of maximum power point always exists due to nonlinear and time-varying characteristics of photovoltaic (PV) generation. To solve this problem, the maximum power point tracking (MPPT) control strategy based on generalized predictive control (GPC) is put forward. Firstly, the theory and feature of PV cell is analyzed, and the MPPT control model is constituted based on Boost circuit....
Abstract Stand-alone photovoltaic system (PV) produces a variance in the output voltage under variable irradiation and temperature, load conditions, resulting control challenges. The research scope is to maintain constant despite variations input or load. use of DC converter ensures that such systems remains regardless changes production on boost employed solve this problem. This paper presents...
Based on the fact that effectiveness of perturb and observe algorithm in a maximum power point tracking (MPPT) photovoltaic array is tradeoff between speed during transient response oscillation around stable level steady state response. To have high speed, incremental step should be high, but this increases MPPT, whereas adopting low reduces time improve condition. This paper presents new based...
To extract the maximum power from solar PV, point tracking (MPPT) controllers are needed to operate PV arrays at their under varying environmental conditions. Fractional Open Circuit Voltage (FOCV) is a simple, cost-effective, and easy implement MPPT technique. However, it suffers discontinuous supply low efficiency. overcome these drawbacks, new hybrid technique based on Genetic Algorithm (GA)...
