The power demand is increasing continuously day by day. The real time power system parameters are continuously changing due to varying loading conditions, internal and external disturbances. The low frequency oscillations (LFO) are a major concern in modern stressed power system. In case if low frequency oscillations are not damped effectively, it may leads to failure of system stability and also...
This work emanates from our personal conviction in renewable energy & its practical effect in the field. The real time data regarding power consumption to demonstrate the impact of solar energy technology is presented here. The improvement in efficiencies is gained due to installation of solar PV modules. The power consumption pattern before and after the installation of renewable energy technologies...
The paper presents system formulation using Polymer Exchange Membrane Fuel Cell. The fuel cells based system is integrated with the grid and implements Fuzzy PID technique to control the triggering circuitry of the inverter. Simulation is done in Simulink/MATLAB to execute the system and plot the corresponding results. The paper represents the mathematical modeling along with the block diagrams and...
The paper depicts the reviews on evolution of a cube shaped device called the Cubli, which has the ability to leap up, create equilibrium on different angles and edges. The study is focussed upon the control techniques when there is a sudden brake on high angular velocity rotation of reaction wheels, which are seated on the surface of Cubli, allowing the Cubli to leap up, first to its edge, and then...
The operation of power system requires maintaining the balance between the load and generation. The system experiences load variations which results deviations in frequency and tie-line power. This generate overshoots and fluctuations in the system. The AGC represents the control of tie-line power flows and the frequency of the system. This paper proposes an optimal fuzzy controller in an interconnected...
A robust PSO optimized fuzzy logic power system stabilizer (PSOFPSS) is proposed in this paper. To damp out the low frequency oscillations and small signal stability enhancement the Fuzzy PSS (FPSS) is added with the excitation system. The single machine infinite bus (SMIB) system is analyzed with Fuzzy PSS (FPSS) and with PSOFPSS. The rotor angular speed deviation and acceleration are considered...
