This paper aims to apply a maximum power point tracking (MPPT) algorithm into a wind turbine with variable speed generator model, jointly the wind energy conversion system (WECS). There are several types of wind turbine in different configurations and their efficiencies in energy extraction are different depending on their aerodynamic designs. In general, their power efficiencies are bounded by...

This paper focuses on the indirect adaptive tracking control of renewable energy sources in a grid-connected hybrid power system. The renewable energy systems have low efficiency and intermittent nature due to unpredictable meteorological conditions. The domestic load and the conventional charging stations behave in an uncertain manner. To operate the renewable energy sources efficiently for ha...

In this study, we build up the double-dynamic models of variable speed wind power systems and design a new type Maximum Power Point Tracking (MPPT) PI-NN controller to improve the precision of the Tip Speed Ratio (TSR) tracking based on the models.

Partial shading and rapidly changing irradiance conditions significantly impact on the performance of photovoltaic (PV) systems. These impacts are particularly severe in tropical regions where the climatic conditions result in very large and rapid changes in irradiance. In this paper, a hybrid maximum power point (MPP) tracking (MPPT) technique for PV systems operating under partially shaded co...

This paper shows the behaviour of of a microgrid which is fed by a PV source and the output of the grid which is controlled by a hysteresis controller . Maximum Power Point Tracking (MPPT) is used to track the maximum power, a Boost (dc to dc) converter is used to obtain the impedance matching between the PV array and the load. A solar inverter is used to convert DC input current to AC current ...

In this paper presents a Maximum Power Point Tracking (MPPT) technique based on the Hill Climbing Search (HCS) method and fuzzy logic system for Wind Turbines (WTs) including of Permanent Magnet Synchronous Generator (PMSG) as generator. In the conventional HCS method the step size is constant, therefor both steady-state response and dynamic response of method cannot provide at the same time an...
