The power generation from HRES, such as PV, FC, and Battery, is heavily dependent on weather conditions, resulting in PQ problems like voltage fluctuations, swells, harmonics, and sags. Rapid adjustment is therefore increasingly necessary in energy transmission and distribution networks. To address these issues, this paper proposes the use of STATCOM for reactive power compensation to mitigate voltage sag, swell, fluctuations, and THD. The paper discusses the modeling of HRES (PV-FC-Battery) and evaluates the fixed operating limit of the system with the integration of STATCOM. The main objective is to optimize gain parameters of FOPID controllers-based STATCOM control circuit using a hybrid deep learning model that includes CNN and RNN, and a hybrid meta-heuristic optimization model to improve voltage stability and response given the irregular nature of HRES. The optimized FOPID controller is evaluated to mitigate PQ issues such as voltage swell, fluctuation, sag, and harmonics. The proposed meta-heuristic optimization model, MADO, is a combination of MAO and DOA. The proposed approach is evaluated using power flow and power quality analyses on the IEEE 9 bus system's power.

“…The fundamental concept is to adjust for basic reactive power from non-linear loads while simultaneously eliminating harmonic distortion [15]. By utilizing a static compensator (STATCOM) hybrid and a serial resistance resistor (SDBR), voltage fluctuations in the low-voltage ride-through capability (LVRT) can be mitigated and the LVRT's performance enhanced [16]. In an effort to address the shortcomings of traditional filters, power utilities have begun implementing a new technology known as shunt active power filters (SAPF) that are powered by voltage source inverters (VSI) based on power electronics [17]- [19].Modern automatic control systems frequently utilize cutting-edge soft computing techniques to optimise the system's parameters.…”

This research study presents the design and simulation of a hybrid active power filter (HAPF) for reducing harmonics. The reference currents have been determined using the synchronous reference frame technique. To achieve its goals, the proposed HAPF employs AI algorithm known as particle swarm optimization (PSO) to fine-tune the proportional-integral PI controller's parameters. With the help of PI-PSO controller the DC link voltage is regulated in the HAPF-inverter. A non-linear current control strategy based on hysteresis employed here to construct the pulse gate by comparing the retrieved reference and real currents necessitated by the HAPF. Simulations were carried out in MATLAB and shown that the proposed method is extremely adaptable and efficient in reducing harmonic currents caused by non-linear loads.

SummaryThis paper proposes leaky least mean fourth (LLMF) algorithm for the control of five‐level series connected H‐bridge multilevel inverter (5L SCHB‐MLI). The SCHB multilevel inverter is a popular configuration due to its wide application for high‐power and medium‐voltage applications. The complete system comprising the grid, load, and compensator is modeled in MATLAB/SIMULINK. Prototype hardware is also developed in the laboratory for experimental validation. The 5L SCHB inverter is connected in a single‐phase power distribution system and controlled as a compensator. The voltage across both DC links of the H‐bridges is regulated to almost equal value by the proposed control algorithm. The closed loop system is designed to mitigate total harmonic distortion (THD) in the source current and improve the power quality of the proposed system. The system is analyzed under the steady state and dynamic state, and the results are also verified on the hardware prototype developed in the laboratory. The proposed algorithm is also compared with conventional least means square (LMS) algorithm and notch filter algorithm on several parameters. The paper discusses a detailed simulation and hardware analysis on the control of five‐level MLI topology.
