This paper proposes the design of maximum power point tracking based on fuzzy logic control for standalone PV system. A complete model of the fuzzy logic maximum power point tracking for standalone PV system is compiled and loaded on the eMEGAsim using the RT-Lab real-time simulation platform from Opal-RT. The effectiveness of the proposed fuzzy logic control has been compared with the perturbation...
A novel algorithm for maximum power point tracking (MPPT) in solar power-generating systems was proposed and compared with the conventional methods of hill climbing, perturbation and observation, and incremental conductance. The three conventional algorithms are prone to divergence under low irradiance levels (<150W/m2), resulting in MPPT difficulties. This study proposed a new MPPT technique based...
When photovoltaic panels are non-uniformly irradiated, they experience shadowing effect and the power against voltage curve will demonstrate multiple peaks which cause maximum power point tracking method to become challenging. A method often used to track the real peak is the two stage searching method which uses a ratio of the open circuit voltage. However, this method has some shortcomings especially...
To improve reliability of micro-grid system without energy storage, a maximum power point tracking (MPPT) algorithm considered spinning reserve capacity was proposed. Using implicit curve fitting method, the algorithm set aside 10% of PV array's maximum output power as spinning reserve of distributed generation (DG), and tracked maximum power point of load in real simultaneously. Moreover, to improve...
