Wind energy, a kind of non-conventional energy source and environmental fresh energy, is widely studied nowadays. Directly driven wind turbine permanent magnet synchronous generator (D-PMSG) plays a vital role in the latest small-scale wind Power technology. This paper presents the modeling and experimentation of a 12kW direct driven Permanent Magnet Synchronous Generator of Wind Power. This model...
This paper presents a robust voltage control intended for a photovoltaic system, the main objectives of the proposed control is to adapt with the parameter variations and load disturbances. Second order sliding mode controller, based on super twisting algorithm for DC-DC Buck converter is proposed. Applying SOSMC can improve the transient response of the system for a wide range of reference voltage...
This paper presents advanced power management strategy for a stand-alone hybrid power system. The proposed system consists of a photovoltaic panel, Proton exchange membrane fuel cell and a battery-electrolyzer-super capacitor energy storage system. All the system components are connected to the same DC voltage bus through appropriate Dc-Dc power converters and supposed to be controlled by independent...
Electric load forecasting is one of the most important areas in electrical engineering, due to its main role for economic and reliable operation in power systems. In particular, accurate medium and long-term forecasts have significant effect on grid expansion planning and future generating capacity scheduling. This paper uses the Algerian electricity demand observations to evaluate methods for medium...
This paper discusses the concept of simple sliding mode to resolve the problem of control of a three-level boost converter for fuel cell applications. Simple sliding mode involves simple sliding surfaces; they are a class of surfaces that reveals the dispersion of nonlinear stabilizing surfaces for a given nonlinear MIMO system. In the case of the three-level boost converter, simple surfaces have...
In this paper, a modified maximum power point tracking (MPPT) algorithm based on particle swarm optimization (PSO) technique is proposed. This algorithm aims to maximize the power extracted from a photovoltaic (PV) system with Lithium-ion (Li-ion) battery under partial shading condition (PSC). The proposed algorithm aims to reduce the time wasted during the exploring phase by using a variable sampling...
This paper describes an application of Artificial Bee Colony (ABC) to load frequency control (LFC) in single, two and multi-area interconnected power systems. The proposed ABC algorithm is used to obtain the optimal values of the proportional-integral-derivation (PID) controller parameters based load frequency control (LFC). The principal function of the LFC loop is to control the frequency and active...
In recent years, it has been proven that one of the main issues in isolated applications is the importance of the dynamic characteristics assessment of three phase self-excited induction generator (SEIG). This paper presents a generalized state-space dynamic model using D-Q stationary reference frame of such a three phase SEIG. The values of self-excitation capacitance and the minimum and maximum...
