“…This above procedure has been implemented sequentially in MATLAB, at a time one controller parameter is tuned while other controller parameters are kept constant. EBFA is applied to solve for optimization problem described in (10) for the constraints in (11). The constraints in (11), are chosen from the earlier work [15].…”

“…For reactive power management and voltage control, reactive power is needed to be balanced under all operating conditions .Hence, it is obligatory to have a sufficient capacity of reactive power source to be present in the OGHPS. The earlier works reported in [4][5][6][7][8][9][10] for voltage and reactive power control of the wind diesel hybrid Power System are based on Static VAR Compensator (SVC) and Static synchronous compensator (STATCOM)] with load either static (exponential type) or static plus dynamic. Some good works have been reported, but, the parameters of the SVC/STATCOM controllers were optimized while controller parameters of automatic voltage regulator (AVR) of SG excitation control were fixed, hence cannot assure the efficient co-operative control.…”

Generally, for remote places extension of grid is uneconomical and difficult. Off-grid hybrid power systems (OGHPS) has renewable energy sources integrated with conventional sources. OGHPS is very significant as it is the only source of electric supply for remote areas. OGHPS under study has Induction generator (IG) for wind power generation, Photo-Voltaic source with inverter, Synchronous generator (SG) for Diesel Engine (DE) and load. Over-rated PV-inverter has capacity to supply reactive power. SG of DE has Automatic voltage regulator for excitation control to regulate terminal voltage. Load and IG demands reactive power, causes reactive power imbalance hence voltage fluctuations in OGHPS. To manage reactive power for voltage control, two control structures with Proportional–Integral controller(PI), to control inverter reactive power and SG excitation by automatic voltage regulator are incorporated. Improper tuning of controllers lead to oscillatory and sluggish response. Hence in this test system both controllers need to be tune optimally. This paper proposes novel intelligent computing algorithm , Enhanced Bacterial forging algorithm (EBFA) for optimal reactive power controller for voltage control in OGHPS. Small signal model of OGHPS with proposed controller is tested for different disturbances. simulation results are compared with conventional method , proved the effectiveness of EBFA.

“…The objective is to develop a control strategy for the STATCOM that can effectively regulate voltage and provide reactive power support to the microgrid, thereby improving its power quality. RES like solar and wind are intermittent and unpredictable, which can create challenges for microgrid systems [10,11]. Energy storage systems combined such as batteries can help to mitigate these challenges by providing a buffer for excess energy and compensating for energy deficits.…”

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.

“…Over the past few decades, there are various techniques that have been proposed for controlling SVC to improve the damping of synchronous engines. Among the methods proposed are proportional-integral (PI) controllers [4,5], proportional-integral-derivative (PID) controllers [6][7][8][9] and lead lag (LL) controllers [10,11]. In this paper, a combination of SVC with PID controller (SVC-PID) has been chosen to improve oscillation stability in power system.…”

This paper discussed the impact of multi-objective function in a swarm-based optimization approach for modulate proportional-integral-derivative (PID) controller parameters of a static var compensator (SVC) in a single machine infinite bus (SMIB) system. SVC is a Flexible Alternating Current Transmission Systems (FACTS) devices which often used to increase the damping of the synchronous generator. In this paper, three parameters of PID controller: proportional gain, KP, interval gain, KI and derivative gain, KD are tuned with particle swarm optimization (PSO) approach. One multi-objective function (MO) that derived from the consolidation of maximum damping factor, σmax and minimum damping ratio, ξmin is proposed to elevate the damping capability of the systems. Validation with respect to speed response and eigenvalues verification proved that the proposed MO is more competent than single objective function.
