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)
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)
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)
In this paper, the operation of three-phase, four-wire voltage source inverter (VSI) under unbalanced voltage conditions is investigated. The inverter is particularly interesting for the simultaneous supply of three-phase and single-phase loads in transformerless hybrid power system (HPS) application. A control strategy for the VSI based on the(More)
MicroGrids (MGs) are one of the most efficient ways to integrate the renewable energy sources in the rural areas. The biogas extracted from the organic waste, an often-unused renewable resource, can be electrically valorised through a Solid Oxide Fuel Cell/Gas MicroTurbine hybrid system. In order to preserve the high electrical efficiency obtained with this(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 useful and efficient ways to integrate the renewable energy technologies in the rural area, which has an often unused renewable resource: the organic waste. The biogas produced by the transformation of this primary energy resource can be valorised in a MG using a hybrid system based on a Solid Oxide Fuel Cell (SOFC) and(More)
