In recent year's renewable energy sources have become a useful alternative for the power generation. The power of photovoltaic is nonlinear function of its voltage and current. It is necessary to maintain the operation point of photovoltaic in order to get the maximum power point (MPP) in various solar intensity. Fuzzy logic controller has advantage in handling non-linear system. Maximum power ...

in this paper, a consistent pattern with the optimal coordinated design of pss and sssc controller to improve the damping of low frequency oscillations is shown. in this design, sensing and signal transmission time delays are considered as effectiveness parameters. the design problem has been considered an optimization problem and biogeography-based optimization (bbo) algorithm is used for sear...

-In this paper, the approach of Generalized Predictive Control (GPC) is applied to a multivariable model of the Dinorwig pumped storage hydroelectric power station. The response of the system with constrained predictive control is compared with the classic PI controller as currently implemented. The results show that GPC offers significantly better performance across the plant’s operating range...

increasing of word demand load caused a new distributed generation (dg) to enter to powersystem. one of the most renewable energy is the photovoltaic system. it is beneficial to use thissystem in both separately as well as connected to power system using power electronics interface.in this paper an optimal pid controller for photovoltaic system systems has been developed. theoptimization techni...

In this paper we develop a non-linear predictive controller for regulating DC-DC power converters. The proposed control strategy is implemented and tested using two models: an averaged non-linear model for control purposes and a switched Buck-Boost circuit model as the controlled plant. A comparison with classical PID control in terms of start-up behavior and robustness to disturbances is given...

This paper proposes analysis and control of a single-phase power factor corrector (PFC). The proposed control is capable of achieving a unity power factor for each DC link voltage or load fluctuation. The method under study is composed of two intelligent approaches, a fuzzy logic controller to ensure an output voltage at a suitable value and predictive current control. The fuzzy controller is u...

A superheater is an essential part of the steam generation process in the boiler-turbine system. Reliable control of temperature in the superheated steam temperature system is necessary to guarantee efficiency and high load-following capability in the operation of coal-fired Thermal power plant. The PI and PID controllers are extensively used in cascade control of secondary superheated steam te...

The technology has proceeded so much that the power system should be substantial and explicit to give optimal results. Ever-increasing complexities of load disparity cause frequency fluctuations leading efficiency degradation system. In order a suitable real output, entails an extremely perceptive control technique. Consequently, advanced method, is, adaptive model predictive controller (AMPC),...
