The increase of the wind power penetration in the electrical grids of Denmark, Germany, Spain and other countries and regions is challenging the stability of the system. The subject of this paper is to review the main problems of the connection of wind farms to the grid and how the grid codes must be adapted in order to integrate wind power generation(More)
In this paper, the implementation of an innovative inverter control strategy based on the symmetrical components is presented. Symmetrical components of the inverter output voltage and current are decomposed into dq DC quantities to control a three-phase four-leg inverter. This kind of inverter can be a good choice for the applications with hybrid power(More)
This paper reports an investigation to develop a dynamic hybrid power system simulation model to maximize the renewable energy extraction and to analyze disturbances. The investigated model is based on two types of renewable power generation: wind turbine generator and photovoltaic generator, connected to a three-phase isolated grid constituted by a diesel(More)
The study of behaviour of the hybrid power systems (HPS) for remote areas is one of research axes of our laboratory. Simulink blocks with models corresponding to all the system parts have been developed. Control laws have been implemented to ensure the optimal power retrieval, the system stability and the output power quality. In order to make possible the(More)
The aim of this research study has been to design a gain scheduling (GS) digital controller in order to control the voltage of an islanded microgrid in the presence of fast varying loads (FVLs), and to compare it to a robust controller. The inverter which feeds the microgrid is connected to it through an inductance-capacitor-inductance (LCL) filter. The(More)
Microgrids (MGs) are one of the most promising electrical systems for the next years. Since the definition of the MG paradigm by the first time, the investigation in this area is growing continuously and there are numerous research projects in this moment over the world. This paper makes a survey focused on two important features of MGs: unplanned islanding(More)
Nowadays, a large part of the world population lives without access to electricity, principally due to the location, too far from the main grid. Renewable power sources connected in an autonomous local grid are a real opportunity for these communities. These weak electrical grids composed by several microsources, energy storage systems and loads can be(More)
