SUMMARY:

The growing use of distributed generators (GDs) causes significant changes in the operation of electric power distribution systems (SDEE), mainly in the predominantly radial ones. In addition, battery energy storage systems (SAEBs) are being used to provide auxiliary services to the grid due to their flexibility to act by injecting or absorbing power, which can mitigate the impact of DG penetration. However, it is necessary to program the actuation of these devices. In this context, this work proposes two intelligent management strategies to plan (day-ahead) the hourly State of Charge (𝑆𝑜𝐶) of a battery connected to IEEE test feeders (34 and 123 bus) with photovoltaic distributed generation. In summary, in the first methodology, two optimization metaheuristics (NSGA-II and MOPSO) were implemented to attenuate load demand peaks, reduce voltage transgressions concerning normative limits and minimize tap changeovers in automatic regulators. In addition, physical and operational constraints are imposed on the mathematical model to bring it closer to reality. The second methodology consists of monitoring the active power of the substation using it as a trigger signal for the dispatch or loading of the SAEB. It is noteworthy that the software Matlab and OpenDSS were selected, respectively, to structure the metaheuristics and calculate the temporal power flow due to their communication capacity. The results show that the traditional actuation by triggering signals ignores several possibilities of actuation, mainly in systems with multiple load peaks of different dimensions. Finally, the metaheuristic approaches stood out among the analyzed objectives.
