Abstract

This paper presents three area multi-unit Deregulated Power System (DPS) for Load Frequency Control (LFC) using Fractional Order Sliding Mode Controller (FOSMC) along with Thyristor Controlled Phase Shifters (TCPS) and Superconducting Magnetic Energy Storage (SMES) combination. The FOSMC can be used to overcome nonlinearities and uncertainties of the system for bilateral and unilateral transactions under diﬀerent Step Load Perturbations (SLPs). The deregulated power system performance is analyzed for diﬀerent Regulation constants (R) such as 1.8, 2.4 and 3.0. For stabilization of oscillations in frequency and to stabilize the deregulated power system dynamically for diﬀerent SLPs, TCPS is incorporated with the tie line in series and SMES is used as an energy storage unit. The dynamic responses of LFC problems have been simulated and analyzed with MATLAB/Simulink-based computer simulations. Further simulation results have also been tabulated as a comparative performance with respect to peak overshoot and settling time.

基于FOSMC的三区多机组无调节电力系统负荷频率控制及调节常数性能分析

本文提出了一种采用分数阶滑模控制器(FOSMC)、晶闸管控制移相器(TCPS)和超导磁能存储(SMES)相结合的三区多机组负荷频率调节电力系统(DPS)。FOSMC可用于克服系统在不同阶跃载荷扰动下的双边和单边交易的非线性和不确定性。分析了不同调节常数(R) 1.8、2.4和3.0时电力系统的解除管制性能。为了稳定频率振荡和动态稳定不同slp下的失稳电力系统，将TCPS串联到并网线路中，并将SMES作为储能单元。利用MATLAB/ simulink对LFC问题的动态响应进行了仿真和分析。进一步的模拟结果也被制成表格，作为关于峰值超调和稳定时间的比较性能。
