Ennoble class topper optimization algorithm based fuzzy PI-PD controller for micro-grid

摘要

The multi-area micro-grid system (MAMG) is a complex nonlinear system. Instability or performance degradation may cause due to inadequate damping under the sudden load fluctuation in the system. Owing to this, to provide uninterrupted electric power with additional attributes, strong and intelligent control methods are curiously necessary for automatic generation control of micro-grid (MG). The utilization of ennoble class topper optimization (E-CTO) tuned fuzzy cascaded proportional-integral proportional-derivative (fuzzy PI-PD), i.e., fuzzy PI-PD controller in frequency control in two areas interconnected MG (isolation mode) with renewable penetration is a novel work. A maiden attempt of the E-CTO is intended to optimize the range of the membership function of the fuzzy controller by employing the integral time absolute error (ITAE) criterion. The effectiveness of the proposed controller is exposed by opposing the dynamic answers of MAMG with a fuzzy PI-PD and traditional controller. In the end, a sensitivity study is offered to show the power of the planned approach to wide fluctuations in the MG parameters, magnitude likewise the situation of step/ random load disturbance. The recommended MAMG and optimization techniques are simulated in the LabVIEW@2015 environment. Also, OPAL-RT based real-time analysis is presented to full-prof the novel work.
