<span lang="EN-US">The application of wind-photovoltaic complementary power generation systems is becoming more and widespread, but its intermittent fluctuating characteristics may have a certain impact on the system's reliability. To better evaluate reliability stand-alone with wind photovoltaic generators, assessment model for generators was developed based analysis generator outages de...

In this paper, the control scheme of a wind energy conversion system for remote sites using fuzzy logic is presented. Two fuzzy controllers are proposed: the first one is dedicated to the maximum power point tracking (MPPT) of a variable speed permanent magnet synchronous generator wind turbine. The second fuzzy controller has the the objective to manage both the production and the storage of e...

Abstract: Model predictive control (MPC) has been widely studied for regulating frequency in stand-alone microgrids (MGs), owing to the advantages of MPC such as fast response and robustness against the parameter uncertainties. Understanding the impacts of system parameters on the control performance of MPC could be useful for the designing process of the controller to achieve better performanc...

Meenakumari.S Department of Electrical and Electronics Engineering,Er.Perumal Manimekalai College of Engineering, Hosur, India Abstract— In this project, a near-unity-power-factor front-end rectifier employing two current control methods, namely, average current control and hysteresis current control, is considered. This rectifier is interfaced with a fixed-pitch wind turbine driving a permanen...

the importance of the hybrid power generation systems (HPGS) increased especially in the last few years. HPGS are used to share the load with the utility grid and these systems are termed as HPGS-utility grid. In addition, they are used to transmit the power to the remote areas. In this case, these systems are termed as stand-alone HPGS. HPGS consist of different power sources such as photovolt...

The main focus of this study is to design a novel stand alone PV-wind hybrid energy system for remote locations where grid extension is not feasible or is expensive. The hybrid PV-wind stand alone energy system shows higher reliability compared to wind or PV stand alone systems as wind and solar technologies complement each other. A Matlab/Simulink model of an integrated stand alone PV-wind hyb...

The optimized dispatch of different distributed generations (DGs) in stand-alone microgrid (MG) is of great significance to the operation’s reliability and economy, especially for energy crisis and environmental pollution. Based on controllable load (CL) and combined cooling-heating-power (CCHP) model of micro-gas turbine (MT), a multi-objective optimization model with relevant constraints to o...

This study deals with system integration and power management of a stand-alone renewable energy (RE) hybrid system, which is in its final stage of construction in Lambton College (Sarnia, Ontario, Canada). The system consists of five main components: photovoltaic (PV), wind turbine, electrolyzer, hydrogen storage tanks and fuel cell. The model for each process component was developed and the hy...

Wind turbines are complex structures and their dynamics vary significantly in operation, in comparison to that under stand still (parked) conditions. Presence of rotational loads and considerable aeroelastic effects makes it difficult to apply conventional system identification techniques to wind turbines. Operational Modal Analysis (OMA) is a technique of determining dynamic characteristics of...

In this paper, a novel method is proposed and applied to quickly calculate the capacity of energy storage for stand-alone and grid-connected wind energy systems, according to the discrete Fourier transform theory. Based on practical wind resource data and power data, which are derived from the American Wind Energy Technology Center and HOMER software separately, the energy storage capacity of a...
