“…A distributed voltage control strategy was proposed for both balanced and unbalanced distribution networks, which functions by harnessing the reactive power capabilities of large-scale decentralized EV chargers [25]. Aiming at the demand of active power and reactive power in frequency and voltage stability control, the effect of simultaneously supporting the voltage and frequency of the grid is achieved by coordinating the charging and discharging active power of EVs and the reactive power of charging inverters [18,26].…”

The study of dispatching methods for large-scale interruptible loads and electric vehicle clusters is of great significance as an optional method to alleviate the problem of overload in interface power flow. In this paper, the distribution model and transfer capacity of large-scale interruptible load and electric vehicle in two dimensions of time and space were firstly introduced. Then, a large-scale interruptible load and electric vehicle dispatching model considering transmission interface power flow balance was established. Finally, a case study was carried out with the city power grid as the research object. Studies show that by dispatching large-scale interruptible load and electric vehicle, the overload rate of interface power flow can be reduced by 12–17%, while the proportion of clean energy generation increased by 4.19%. Large-scale interruptible load and electric vehicles are quite different in terms of the role they play in grid regulation. The regulation cost of electric vehicles is higher than that of large-scale interruptible load, but it also has the advantages of promoting the consumption of clean energy and improving the overall operating economy. Which type of resource should be given priority is based on the actual state of the grid. In addition, the cost of electricity has a significant impact on the load response behavior of electric vehicles. It should be determined according to various factors, such as interface power flow control requirements, regulation costs, and power grid operation costs.

“…Among the metaheuristic techniques available of late, EO has emerged as a prominent algorithm since its inception by Faramarzi et al [43]. Predominantly used for load frequency control methods [44], [45], EO has now gained popularity in process control applications [1], [2], [34], [46] with its ability to simultaneously tune multi-parameters to achieve the desired performance.…”

Repositioned Internal Model Control Strategy on Time-Delayed Industrial Processes With Inverse Behavior Using Equilibrium Optimizer

et al. 2023

This paper investigates a repositioned inner-loop stabilized internal model control technique for demanding inverse response industrial processes and bioreactors with integrating/unstable dynamics. A proportional-derivative controller based on Routh stability principles is used to achieve stabilization. For set-point pursuit, the servo controller is built by applying the relocation internal model control principle to the stabilized plant model. The metaheuristic equilibrium optimizer methodology is used to achieve the optimal controller settings of the proposed method. The recommended technique is investigated for managing inverse response processes such as the steam drum level control system, concentration in enzymatic reactors, and continuously stirred tank reactors. A thorough examination of the proposed scheme's stability and robust performance is also provided. It provides significant improvement in performance metrics when compared with some of the recently reported strategies. Particularly, for the steam drum system, the suggested strategy yields an improvement of over 47% in the disturbance rejection and more than three times faster servo response when compared with the recently reported integral proportional-derivative double control loop strategy.INDEX TERMS Inner-loop stabilization, repositioned internal model control, integrating and unstable processes, inverse response, time delay, equilibrium optimizer.
