Electricity consumers desire a reliable and uninterrupted power supply for their equipment. Frequency and voltage are fluctuated due to the increase in intermittent renewable sources in the power systems. To mitigate these problems, a novel multi‐term fractional‐order PID (MFOPID) controller is proposed for improving the combined voltage‐frequency control of a three‐area hydrothermal system (THS) that incorporates a realistic dish‐Stirling solar thermal system (RDSTS). Suitable nonlinearity constraints are considered in both thermal‐hydro units. The proposed controller parameters are optimized using the artificial flora algorithm. Electric vehicle (EV) fleets have been introduced for the first time into the system under consideration. The MFOPID controller outperforms the PID with filter coefficient (PIDN) controller, according to a comparative assessment of the system dynamic responses under various investigations. Investigations exhibit that the system dynamic performance marginally degrades after the incorporation of the RDSTS into all control area of the three‐area THS. The analysis reveals that the assimilation of EVs into the considered system provides better system damping and reduces oscillations and peak deviations. The efficiency of electric vehicles is influenced by battery state‐of‐charge (SOC). The system performance deteriorates when the SOC of the EVs is more than 80% charging and less than 50% discharging at the time of disturbance. Moreover, the MFOPID controller provides a faster injection of EV power into the system during perturbation compared to the PIDN controller. Sensitivity analysis validated the MFOPID controller's sturdiness against numerous physical system conditions.

“…The IPSO-based CPSS controller for single-area nonlinear IPS was proposed by Javed and Zahra. Their power system model combines hydro, thermal reheat, and gas production units [9]. Naga Sai Kalyan and Sambasiva examined a DE-AEFA-based PID control scheme for a two-area IPS in the presence of nonlinearities such as GRC.…”

Existing interconnected power systems (IPSs) are being overloaded by the expansion of the industrial and residential sectors together with the incorporation of renewable energy sources, which cause serious fluctuations in frequency, voltage, and tie-line power. The automatic voltage regulation (AVR) and load frequency control (LFC) loops provide high quality power to all consumers with nominal frequency, voltage, and tie-line power deviation, ensuring the stability and security of IPS in these conditions. In this paper, a proportional integral derivative (PID) controller is investigated for the effective control of a four-area IPS. Each IPS area has five generating units including gas, thermal reheat, hydro, and two renewable energy sources, namely wind and solar photovoltaic plants. The PID controller was tuned by a meta-heuristic optimization algorithm known as a gradient-based optimizer (GBO). The integral of time multiplied by squared value of error (ITSE) was utilized as an error criterion for the evaluation of the fitness function. The voltage, frequency, and tie-line power responses of GBO-PID were evaluated and compared with integral–proportional derivative (GBO-I-PD), tilt integral derivative (GBO-TID), and integral–proportional (GBO-I-P) controllers with 5% step load perturbation (SLP) provided in each of the four areas. Comprehensive comparisons between GBO-PID and other control methodologies revealed that the proposed GBO-PID controller provides superior voltage, frequency, and tie-line power responses in each area. The reliability and efficacy of GBO-PID methodology were further validated with variations in the turbine time constant and speed regulation over a range of Â ± 25%. It is evident from the outcomes of the sensitivity analysis that the proposed GBO-PID control methodology is very reliable and can successfully stabilize the deviations in terminal voltage, load frequency, and tie-line power with a shorter settling time in a four-area IPS.
