Energy Management System in Bidirectional DC-DC Converter for Microgrid

In microgrids and energy storage systems that use synchronised power delivery and operationalstability, DC-DC converters are crucial components. This study proposes a closed-loop proportionalintegral (PI) based energy management control technique to assess and solve unstable DC link voltageproblems. In grid-connected mode, battery units and a hybrid energy storage system (HESS), such as asuper-capacitor (SC), are charged by separate hybrid energy resources, such as solar and wind. Theprimary goal of this effort is to supply the grid with energy storage units (supercapacitor and battery) inthe event that solar or wind energy supplies are unavailable. To meet the stability requirement, wind andsolar power generation is first controlled by the energy management control. In order to increase systemflexibility and compatibility with various PV cell and wind energy sources, the MPPT technique has beentaken into consideration. The maximum power was effectively tracked by the suggested system, and theincremental conductance (IC) technique based on galactic swarm optimisation (GSO) is used to assess thedata. GSO should be used in MPPT to obtain a high convergence rate and less steady-state oscillation. TheMATLAB/Simulink platform is used to implement the entire project, and the suggested algorithm'sperformance is compared to that of the current ones.
