“…The Second-Order Algorithm (SOA) dynamically adjusts the gains of the PID controller, significantly enhancing the power quality of the diesel generator system. By employing a Triple Action Controller (TAC), it is possible to achieve regulation of voltage and frequency, minimize voltage Total Harmonic Distortion (THD), and control the current flow between inverters that are parallel [33]. Implementing a TAC control approach with droop and secondary optimized parameters can effectively decrease the circulating current between the inverters and enhance power sharing .…”

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.

Renewable energy sources seem more feasible and cost-effective than power plants using fossil fuels for power generation. Maintaining an appropriate power balance between the source and the demand is almost impossible since renewable energy sources like wind and solar are unpredictable and have fluctuating loads. Microgrids are being elevated as an effective technique for combining small-scale distributed energy sources to produce electricity at the distribution voltage level. Because of the nature of the energy formed, some of the energy produced from these sources cannot be used immediately. Power electronic interfaces are required for the flexible, secure and reliable functioning of distribution systems between micro sources. Dealing with power quality concerns is among the main technical difficulties in the operation and control of microgrid systems that are either grid-connected or stand-alone. These significant issues are mostly caused by the design, mode of operation, nature and performance of distributed energy sources in the microgrid system. Current and voltage harmonics, voltage sag/swell, fluctuation and unbalance are the main power quality problems brought on by the large penetration of distributed generators, nonlinear and unbalanced loads. This study intends to analyze major power quality challenges and the control mechanisms that have been developed for enhancing the power quality in microgrids.
