The ongoing energy transition is driving the transformation of the traditional centralized electric system into a decentralized one, integrating distributed energy resources (DERs) along the grid. This paper presents a ...

One of the main concerns regarding traditional battery energy storage systems (BESS) is how to solve issues related to cell inhomogeneities. This problem commonly ends up reducing the accessible energy level, especially ...

El presente artículo trata de optimizar el uso de las baterías en instalaciones fotovoltaicas aisladas. Por un lado se trata de aprovechar al máximo la energía almacenada a la vez que se estudian los factores que afectan ...

Los sistemas fotovoltaicos aislados de la red eléctrica están generalmente compuestos por una agrupación de paneles fotovoltaicos, un elemento de almacenamiento como baterías, un convertidor DC-DC que actúa como cargador ...

The wide deployment of inverter-based resources is changing the grid characteristics and demanding rapid changes in the control and operation of power grids. Storage is becoming a key component of this transition, as it ...

The non-uniform flux density distribution inside magnetic cores leads to increased overall losses when compared to the commonly used uniform flux density assumption. This effect is amplified if rectangular based core shapes ...

The ageing of insulation systems in electric machines can compromise partial discharge-free designs. Regularly monitoring insulation health is crucial to prevent unexpected failures. Several authors have proposed health ...

In the present paper a partial power converter is proposed for an electric vehicle fast charging station. The main advantage of this type of converter is that it only processes a reduced percentage of the power consumed ...

This work addresses limitations of the composite improved generalized Steinmetz equation for core loss calculation and presents a more robust definition of the losses. First, the limitations due to extrapolation of the ...

This paper evaluates and compares the performances of non-modular and modular battery systems. The modular architecture consists of several battery modules that are individually controlled by means of their corresponding ...
