Resumen:
The storage of energy produced in an unconventional way to reduce the consumption peaks that saturate the electrical network, is reaching a physical limit that will be difficult to overcome, expensive and it will take a long time to develop new technologies that exceed this limit. The use, collection and accumulation of energy must be studied together to achieve efficient results, bypassing the problems described above. Thus, Virtual Power Plants (VPPs), which coordinate the consumption and accumulation profiles of a set of housing units through remote software, allow the energy sharing of different houses in an efficient way.However, to properly operate these plants must be mastered in depth all the dynamic phenomena that occur in all parts forming those lithium batteries at times of charging, discharging and relaxation. And to achieve this objetive it is necessary to have simplified mathematical models of quick and easy resolution, since one of the main objectives of these plants is the prediction of certain variables, and to make decisions of operation of fast way.In this work, a simplified mathematical model used to predict the operation of lithium-ion batteries is presented in detail [1], considering that the electrodes of the batteries are made up of particles of a single size. Through reforms of this model, the evolution of the main variables involved when considering a battery with a particle size distribution are shown [2]. An analysis of the effect of the thermal variables is performed. And finally, with a mechanism similar to that shown in [3], the response of a set of lithium batteries used to satisfy the electrical demand of a typical South American house, connected to a commercial solar panel, is analyzed. From this, the conformation of a VPP is shown.
