Design of Fractional Order Controller Integrated with Renewable Resource in Multi Area Islanded Microgrid

Abstract

This paper presents on designing of fractional order controller, integrated with renewable energy sources in multi-area islanded micro grid. For automatic generation control (AGC), thermal plants in each area with solar thermal power plant (STPP) in area-1 are implemented here. The generating ratios of areas are 1:2:4. Area -1 consists of STPP and thermal plant. Appropriate generation rate constant (GRC) is taken for all the three areas. Hybrid proportional integral derivative (PID) with filter via fractional order integral derivative (PIDN-FOID) controller is considered. Multi verse optimizer (MVO) optimisation technique is used to tune the controller gains. It is observed from simulation results that proposed hybrid PIDN-FOID outperforms as compared to conventional controller. Sensitivity analysis has been performed to test the robustness of suggested approach.
