Some Studies On Frequency Enhancement Of Multi Area Multi Source Power System With Dc Link By Computational Intelligent Techniques

Abstract

The voltage and the frequencies are the main key factors in power systems. The control newlinestrategy is given to these two parameters for smooth performance in power systems. As newlineper the requirement of power in power systems the interconnections between two systems newlineis by tie line, which give economical operations. As per the dependences the control newlinestrategy is Primary, Secondary or emergency control. Here, the Primary control is used newlinefor small frequency changes and the higher frequency changes can done by the secondary newlinecontrol strategy, But the emergency control is used when there is a bigger mismatch newlinebetween consumer demanded load and the generation. For this smooth operation various newlinetechniques used like ALFC control or AGC control or AVR control. Modern electric newlinepower system widely uses HVDC transmission links due to their numerous technical and newlineeconomic advantages. Therefore, HVDC dynamic models have been considered in LFC newlinestudies to investigate their impacts. Again for accurate management and smooth newlineoperation there are some intelligent optimization techniques used like IPSO, IWO or newlineLVFSO. Significant achievements in system dynamics in terms of frequency and tie line newlinepower variations by using diversity of power resources and more robust solution newlinetechniques. These intelligent techniques are used to tune the controller parameters to newlineachieve robustness and accurate power system performances. newline
