Maximum Power Point Tracking of Multiple Photovoltaic Arrays: A PSO Approach

Abstract:The energy demand is increased now days and the non-renewable energies are produce high environmental hazards and its reduced by the renewable energy resources. In solar energy is convert electrical energy which help of photo voltaic (PV) generation. The solar energy efficacy reduced because of climatic change, so need to track maximum power point of PV. The maximum power point tracking (MPPT) methods like perturb-and-observe (P&O) method is used to track only the first local maximum point (LMP) the progress. MPPT methods based on Fire Fly Algorithm (FA) used to track the global maximum point (GMP). But the problem associated with the FA algorithm is produce long time for searching the LMP. This paper reports a hybrid method, which combines P&O and FA methods. First, the P&O method is used to find the local maximum point. Then, starting from that point on, the FA method is used to search the GMP. The advantage of the proposed the time that is required for convergence improved.

“…The power electronic converter must track the MPP of the PV cell [24][25][26] without modifying the mains voltage and frequency [13][14][15]. The conversion stage can be subdivided on the basis of the number of conversion stages (single or double) and on the basis of topology (e.g., centralized, string, modular, distributed).…”

Abstract:The increasing penetration of renewable sources with power-electronic interfaces in power systems is raising technical problems and the overall efficiency of photovoltaic systems can decrease dramatically. In this context, the optimal layout for the photovoltaic system is required. The most adequate strategy to connect the renewable system to the electrical power grid or to supply the end users must be adopted. The present paper proposes a design layout of a PV plant using a DC bus system to improve the overall energy conversion efficiency. An analysis of steady-state system stability, voltage drop and DC cable conduction losses is conducted. The leakage currents to the ground are investigated through simulations. Experimental results are shown focused on the analysis of optimal layout of photovoltaic systems under particular operating conditions.

Abstract-A modified perturbation and observation controller for maximum power point tracking of partially shaded photovoltaic systems is proposed. The proposed controller applies scanning and storing stages to the conventional perturbation and observation technique during partial shading conditions. Moreover, the proposed system is capable to identify whether the photovoltaic system is under partial shading condition or not. The proposed system provides accurate and fast convergence to the global maximum operating point during different weather conditions. Simulation results are provided to demonstrate the validity of the controller.Index Terms-Photovoltaic, partial shading, maximum power point tracker (MPPT), perturbation and observation.
