Currently, Electric Vehicles (EV) and renewable energy sources are being integrated into the main grid to mitigate carbon emissions. Load Frequency Control (LFC) was a significant challenge in renewable and electric vehicle-integrated smart restructured power systems. This paper introduces a fractional order observer-based optimal state feedback controller (FROOSFC)during load frequency control within a two-area Smart Deregulated Power System (SDPS),incorporating thermal-wind resources in control area 1 and hydro-solar-thermal resources within control area 2, with electric vehicle aggregators integrated into each control area. The simulations
are conducted employing the MATLAB simulation environment to simulate the bilateral contract scenario of SDPS. The efficacy of FROOSFC when compared with both the fractional order optimum state feedback controller including the FOPI controller within a potential bilateral contract context, addressing uncertainties and abrupt load variations.
