05 Mar 2021TL;DR: In this article, a 3-bus electrical power system model is analyzed and a PID sliding surface-based sliding mode control is designed to control undesirable chaotic behavior in the proposed power system and obtained results show successful achievement of the objectives.
Abstract: This paper exclaims analysis of bifurcation and chaos phenomena in a 3-bus electrical power system model. The nonlinear dynamic modeling of proposed power system is achieved using generator, load models and equivalent circuit of 3-bus model. The reactive power of the motor is considered as a varying or bifurcation parameter and existence of dynamic behaviors like bifurcation and chaos in 3-bus power system model is discussed via. phase plane, time series plot, bifurcation diagram, Lyapunov spectrum and Poincare map. PID sliding surface-based sliding mode control is designed to control undesirable chaotic behavior in the proposed 3-bus power system and is not available in the literature. Simulation is achieved in MATLAB environment and obtained results show successful achievement of the objectives.

01 Oct 2019TL;DR: A reduced switch single DC source cascaded H-bridge multilevel inverter (RSDCHBMLI) is proposed for DSTATCOM operation and the performance of the current based controller is found to be better than the conventional DC-bus controllers under the test conditions.
Abstract: The application of multilevel inverters (MLIs) for the realization of Distribution Static Compensator (DSTATCOM) overcomes the requirement of higher power rating of switches. However, the high component count and multiple DC-link capacitors in conventional MLIs make the inverter design complicated. These inverters also require additional controls and circuits for DC-link capacitor voltage balancing for its satisfactory multilevel output. This paper proposes a reduced switch single DC source cascaded H-bridge multilevel inverter (RSDCHBMLI) for DSTATCOM operation. The RSDCHBMLI uses a single DC-link capacitor and hence eliminates the problem of capacitor voltage balancing. The topology also leads to reduction in component count along with inherent isolation. FCS-MPC current control is implemented to perform load compensation in presence of feeder impedance along with maintaining sinusoidal voltages at the point of common coupling (PCC). This paper also implements a current based DC-bus voltage controller which allows easier calculation of the controller gain parameters. The performance of the current based controller is found to be better than the conventional DC-bus controllers under the test conditions and results are presented for a 11-kV distribution system simulated in PSCAD/EMTDC environment.

TL;DR: In this article, a linked simulation-optimization model is developed to minimize the total construction cost of the groyne project, and a constraint in terms of low flow speed in a predefined zone is incorporated, which helps in bank erosion prevention.
Abstract:
This paper presents a novel approach for determining the best combination of groynes in terms of their number, lengths and positions for controlling bank erosion. The vulnerable bank is considered to be protected if a very small value of water flow speed is achieved on the near bank area. A linked simulation–optimization model is developed in this regard which minimizes the total construction cost of the groyne project. At the same time, a constraint in terms of low flow speed in a predefined zone is incorporated, which helps in bank erosion prevention. In the simulation model, the depth-averaged shallow water equations are solved using a finite difference scheme. The optimization problem is formulated in three different approaches to tackle different types of in situ field problems. Genetic algorithm (GA) is used to solve the optimization problem. The proposed optimization model is used in two hypothetical test cases including one straight channel and one meandering channel. The results obtained with all the three formulations are found to be logical and establish the potential of the present model for application in real cases.

TL;DR: In this paper, the surface activity of spray deposited Cu doped SnO 2 thin films was studied at different temperatures and compared using the cole-cole plots of ethanol absorbed films to that of unexposed thin films and showed that the electron scattering process was homogeneous in nature and the film had a narrow relaxation time.
