Abstract
According to the 2029 Ten Year Energy Expansion Plan, there are a trend in applying battery energy storage system (BESS) in photovoltaic (PV) plants. In this context, this work presents an elaboration of an optimal energy management system (EMS) for a joint operation of BESS in centralized PV plants (PV/BESS). This article aims to determine an objective function to optimize it, maximizing the profit concentration of a PV/BESS system applied to the simulated centralized PV plant of Coremas. For the system model the considered variables are, energy pricing model, batteries degradation and losses model and a penalty due to power limit violation. The operation optimization was achieved through the use of genetics algorithm. System simulations performed in MATLAB obtained positive results for the proposed EMS, obtaining an average profit gain of 2.11% for 2021.
