LFC of a Deregulated Power System Using Opposition Based Novel Arithmetic Optimization Algorithm Based Fraction Order Cascade Controller

Abstract

AbstractSeveral changes have occurred in the electrical power system during the previous decade, owing to continually growing load demand, quick diminution of fossil fuels, rapid industrialization, and newly implemented electrical-deregulation policies. Several reviews of literature on the topic of Load Frequency regulation (LFC), which copes with varied and modern controller techniques for the effective functioning of the power system, have been produced in the last few years. This research article discusses the Novel utilization of opposition-based Airhmetic Optimization Algorithm (OAOA) for twin areas, multiple-source of linked power system considering Thermal and Hydro in one zone and Thermal and Gas in another zone. For a practical approach, non-linear constraints such as boiler agitation (BD) effects, Time-delay, and generation-rate-constraint (GRC) have been included for each unit. A Novel cascade combination of 2-Degree-of Freedom PI controller (2DOF-PI) and Fraction order Proportional-derivative controller considering filter (FOPDN) is used as a proposed controller in the scheme. The gain parameters of the (2DOF-PI) with FOPDN controller have been improved by the opposition-based Arithmetic Optimization Algorithm (OAOA). Later, the supremacy of the suggested algorithm is verified among the other well-known meta-heuristic approaches like particle-swarm-optimization (PSO), Wild-horse-optimization (WHO), and Artificial-bee-colony (ABC) by evaluating under the same test conditions. To ensure the efficiency of the prospective work the progressive response of the suggested controller to load interuption is correlated to the schematics of current controllers.KeywordsLoad frequency controlOpposition-based arithmetic optimization algorithmDeregulated power system(2DOF-PI-FOPDN) controller
