Modelado y dimensionamiento de sistemas de generación renovable y almacenamiento de energía para microredes AC/DC con capacidad de conexión on-grid/off-grid.

Abstract

This research aimed to model and dimension a generation and storage of renewable energy system far the AC/DC microgrid with on-grid/off-grid connection capacity. Far which the type of microgrid model was defined by using the irradiance and temperature values to January 2021 from Santo Domingo city, a Boost elevator controller, an inverter, a control based on fuzzy logic, anda simulation time of 24 seconds; the implementation was given using the Matlab/Simulink 2018b software. The control is based on fuzzy logic far verification of battery charge or discharge, in such a way that if the panels fail to supply the demand and the batteries do not contain energy, the Electric power distribution network is used; on the other hand, If the battery is charged, it comes into operation, and the power from the grid is not used, in this way the user fulfills an on-grid/off-grid connection. To analyze the results, a comparison was made with a PID controller to verify that the flow is 500kw of average power and confront the charge and discharge curves of the user's battery with on-grid and off-grid connections, obtaining energy management. It is concluded that the fuzzy control following the methodology implemented in the microgrid shows the on-grid and off-grid connection and covers the power requirement; depending on the case, the on-grid or off-grid connection is evidenced. lt is recommended in the research that a genetic algorithm be applied far better optimization and energy management in its operation.
