“…A novel perspective on the various dynamic responses of the two basic microgrid controls, single-and multi-loop droop control, is demonstrated by the authors of [6]. In [7], a droop-controlled system with a static compensator has been designed to enhance microgrid power quality. V/f controllers can be utilized in the DEG autonomous mode, as demonstrated by the authors of [8].…”

This paper discusses the importance of microgrids in power systems and introduces a new method for enhancing their performance by improving the transient voltage response in the face of disturbances. The method involves using a hybrid optimization approach that combines driving training-based and particle swarm optimization techniques (HDTPS). This hybrid approach is used to fine-tune the system’s cascaded control scheme parameters, based on proportional–integral–accelerator (PIA) and proportional–integral controllers. The optimization problem is formulated using a central composite response surface methodology (CCRSM) to create an objective function. To validate the suggested control methodology, PSCAD/EMTDC software is used to carry out the simulations. The simulations explore various scenarios wherein the microgrid is transformed into an islanded system and is subjected to various types of faults and load changes. A comparison was made between the two proposed optimized controllers. The simulation results demonstrate the effectiveness of using a PIA-optimized controller; it improved the microgrid performance and greatly enhanced the voltage profile. In addition, the two controllers’ gains were optimized using only PSO to ensure that the outcomes of the HDTPS model demonstrated the same results. Finally, a comparison was made between the two optimization techniques (HDTPS and PSO); the results show a better impact when using the HDTPS model for controller optimization.

“…Active power filters (APFs), distribution static synchronous compensators (DSTATCOMs) and unified power quality conditioners (UPQCs) are applied to solve different power quality problems. Though they have the advantages of a good compensation effect and little resonance problems, the initial construction costs are high [3][4][5][6][7]. The hybrid APFs (HAPFs) are then proposed by combining the passive capacitive impedance in series/parallel with the APFs (PPF+APFs [8][9][10], PPF//APFs [15,16]), which can reduce the system cost and obtain an excellent effect within a small capacity.…”

In this paper, an open‐circuit fault‐tolerant topology of LC‐coupling hybrid active power filter (LC‐HAPF) and its control strategy are proposed at the switch level, which can greatly improve the reliability of the system. The proposed structure has a contactor between the midpoint of each bridge arm and the negative bus of the dc‐link capacitor. When a single‐phase fault occurs, the proposed LC‐HAPF can be reconstructed into a three‐phase four‐switch system to compensate for the harmonic and reactive power, while the power quality compensation effect is hardly affected. When a two‐phase fault occurs, the operation of the normal bridge arm is not affected, and the two faulty bridge arms can suppress harmonic current and compensate for a fixed reactive power through the passive filters. When the bridge arms all fail, the whole device acts as a passive filter to suppress the harmonic current of the load and to compensate for reactive power as well. Finally, the effectiveness of the proposed topology and its control strategy is verified by simulation and experiment results.

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.
