“…The incremental power flow through DC link (DPtie dc ) is modeled with incremental change in frequency at rectifier end [47]. The representation of transfer function model of DC link is taken from [45][46][47][48][49][50][51][52] as shown in Fig. 2.…”

“…Another is poolco based transactions in which GENCOs of an area for AGC have contracts only with the DISCOs of their own area [30,31]. The AGC of interconnected restructured power systems is discussed in details in [5,6,[29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46]55]. The AGC study under deregulated environment should be designed to accommodate all power contracts possible like poolco based, bilateral and a combination of these two transactions.…”

“…Hence, in order to enhance controllability, one important application of HVDC transmission line is, operating in parallel with an existing AC transmission line acting as AC/DC parallel links interconnecting any two control areas. In literature, AGC of a two-area power system interconnected via AC/DC parallel links, is carried out by using optimal AGC regulators in deregulated mode [45,46]. In addition, AC/DC parallel links in conventional power systems are found in the literature employing sliding mode control [14], optimal control [10,[47][48][49], sub-optimal control [50,51] and differential evolution [52] based control techniques.…”

“…Compliance with North American electric reliability council (NERC) control performance standards (CPS) for AGC under deregulated environment, are discussed in [31,41]. Recently various control strategies are reported in the literature for AGC of restructured power systems such as trajectory sensitivities using gradient Newton algorithm [30], eigenstructure assignment technique [31], H 2 /H 1 control [32], neural networks [33], firefly algorithm [34], hybrid neuro fuzzy [35], genetic algorithm [34,37,38], bacteria foraging [41,42], non-integer controller [42], active disturbance rejection [43], fuzzy logic controller [34,44,45], particle swarm optimization [45] and optimal control [31,45,46].…”

“…In the deregulated environment, the vertically integrated utilities (VIUs) no longer survive. In the deregulated structure, several independent entities like distribution companies (DISCOs), generation companies (GENCOs), transmission companies (TRANSCOs) and independent system operator (ISO) have been introduced [5,6,[29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46]. ISO is independent, disassociated agent for market participants who perform various ancillary services and among them is the AGC [30].…”

Summary In this paper, automatic generation control (AGC) of a two‐area multi‐source power system interconnected via alternating current/direct current (AC/DC) parallel links under restructured power environment is proposed. Each area is equipped with multipower generating sources such as thermal and hydro/gas. To execute the different market contracts in restructured power system, the optimal regulators are designed and implemented using optimal control theory. It is observed that the system dynamic results effectively satisfy the AGC requirements in restructured power system, as well as the system dynamic performance is improved by using AC/DC parallel links in comparison with that obtained with AC link as an area interconnection between the control areas. Furthermore, the eigenvalue study is performed to examine the system stability with and without AC/DC parallel links. Finally, the effectiveness of the optimal regulators is checked for the system under study with physical constraints like time delay, boiler dynamics, generation rate constraints, and governor dead band nonlinearity and variations in system parameters from the nominal values. It is shown that the optimal regulators optimized for linear system are robust enough and work well in the proposed realistic AGC system incorporating physical constraints and wide variations in parameters.

In today's rapidly evolving interconnected electric power system network, ancillary service such as automatic generation control (AGC) plays a critical and important role in safeguarding the system's power supply quality by establishing an equilibrium between generation and load demanded plus losses. A power system with a robust and smart AGC strategy is obligatory for better power quality and system security. Cascade control schemes cope up better with nonlinearity by tuning the gain of controller of power system amid continuous load changing. Therefore, in this article, a supplementary control approach that is, cascade optimal controller‐proportional integral with derivative filter (COC‐PIDN) is suggested for AGC performance advancement of the power systems under deregulated environment. The OC designed consuming full state feedback control approach acts as master controller and PIDN plays the role of slave controller. The nature inspired salp swarm algorithm is employed to adjust the PIDN parameters. Initially, the efficacy of the COC‐PIDN control‐method is explored on a two‐area restructured reheat thermal system and then to validate its excellence and extensibility, the study is protracted to restructured two‐area thermal‐hydro system. Extensive analysis of the findings establishes that the dynamic performance of the COC‐PIDN controller is more valuable than the OC and COC‐PID approaches. The results of COC‐PIDN get further improved in presence of redox flow battery. Finally, the sensitivity analysis as well the acquired results with the COC‐PIDN controller with system nonlinearities demonstrate its robustness.
