Abstract

New concepts of power generation, the emergence of renewable energies as well as the liberalization of the electrical market have recently raised strong intereset in electricity storage technologies. The vanadium redox flow battery (VRB) is among the new storage systems actually developed. A model of VRB storage system is presented in this article based on thermodinamics and electrochemistry. The stack voltage and the different concentrations of vanadium species are determined by the model and depend on the operating state of the system. Finally, a 24h simulation of a system composed of a photovoltaic source, a VRB and a typicaluser is presented. The aim is to improve the specifications of the static converter interfacing the different components of a VRB electricty storage system.

Energy storage

Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent heat and kinetic. Energy storage involves converting energy from forms that are difficult to store to more conveniently or economically storable forms.

Cost of electricity by source

Different methods of electricity generation can incur a variety of different costs, which can be divided into three general categories: 1) wholesale costs, or all costs paid by utilities associated with acquiring and distributing electricity to consumers, 2) retail costs paid by consumers, and 3) external costs, or externalities, imposed on society. Wholesale costs include initial capital, operations & maintenance (O&M), transmission, and costs of decommissioning.

Vanadium redox battery

The vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) or vanadium redox flow battery (VRFB), is a type of rechargeable flow battery. It employs vanadium ions as charge carriers. The battery uses vanadium's ability to exist in a solution in four different oxidation states to make a battery with a single electroactive element instead of two. For several reasons, including their relative bulkiness, vanadium batteries are typically used for grid energy storage, i.e.
