Management of power in AC/DC Hybrid micro grids and harmonic analysis with and without D-STATCOM with different load condition

Abstract

Renewable energy is the source of energy, and in the present situation, the electricity demand is increasing, similar to increasing the population, so the consumption of electricity is rising. There are many problems in solar energy due to fluctuations in the voltage, frequency, mismatch of load, and many stability issues in power generation. Therefore, that improves the power quality and ESS, fuel cell. In this paper, the alternate current /direct current micro grid to invent depend on the generator photovoltaic solar cell (PV) & the energy storage system (ESS). The help of with or without D -STATCOM in the alternate and direct current hybrid micro grid, controls the power demand. Ac-dc buses are interconnected with bidirectional converter. The (IC) interlinked converter is used when the alternate current /direct current flank is affected by the active power shortage. Specifically, the distributed static synchronous compensator (D-STATCOM) at work as the Alternate Current micro grid cannot deliver the reactive power response. A dc-dc boost converter is used to boost out the (IV) input voltage from the photovoltaic, which is come from the Direct current bus. In this structure, the nonlinear load is examined with different loads, e.g., inductive pulse, which is connected to the alternate current side bus. The mat lab 2022b for the power management of two ac/dc under different conditions verifies the proposed scheme with highly efficiency, optimization, trustworthiness, & strength in the islanding mode.
