This paper presents hybrid model predictive control-based automatic generation regulator design for dominant wind energy penetrated multisource power system. The other power generation sources hydro and thermal are also considered in each area. The proposed AGC regulator is designed for each independent area considering only local power system states to ensure the stability of closed-loop system under small perturbation. The performance of the proposed AGC regulator has been validated for 2% step load perturbation. Furthermore, system parameter is varied to 20% of nominal value to assess the robust performance of the regulator. Performance evaluation between the hybrid MPC, conventional MPC, and traditional AGC regulators considering the dominant participation of the DFIG wind turbines is presented to demonstrate the superior performance of the hybrid MPC AGC regulator.
This paper presents real time simulation to analyze the behavior of discrete controller for interconnected power system. A two-area interconnected power system consisting of non-identical power plants with EHVAC transmission link as interconnection is considered for investigations. The hydro and nuclear power plant comprises of area-1 and area-2 respectively. In this paper new control strategies for digital controller is developed depending on the sampling time to test the controller in the non real time simulation environment and transform the controller into a real-time prototype controller, which is used for testing the algorithm in real working conditions. The real time simulation provides a quick solution for prototyping new functions in different types of industrial processes and devices controlled with a complex distributed control system. The real time simulation uses the discrete model of the AGC. Hence discrete controller for the AGC is derived from the continuous controller by discritization of the continuous controller using Tustin transformation, or trapezoid approximation method and the closed loop stability is checked by taking the bode of the closed loop of AGC model for different sampling time periods ,the dynamic response plot for 1% load disturbance in area-1. The discrete controller is prototyped and the real time simulation is performed to observe the results, the dynamic response plots are obtained for 1% load disturbance in area-1 of the real time model.
IJAAC addresses the evolution and realisation of the theory, algorithms, techniques, schemes and tools for any kind of automation and control platforms including macro, micro and nano scale machineries and systems, with emphasis on implications that state-of-the-art technology choices have on both the feasibility and practicability of the intended applications. This perspective acknowledges the complexity of the automation, instrumentation and process control methods and delineates itself as an interface between the theory and practice existing in parallel over diverse spheres. Contents: IJAAC publishes design, realisation and operation of automation and control related original papers, review papers, technical reports, case studies, tutorials, conference reports, book reviews, notes, commentaries, and news. Special Issues devoted to important topics in automation and control technology infrastructure will occasionally be published.
