The Time Domain

A new analysis method using wavelet domain for steady-state operating condition of power system is developed and introduced. Based on wavelet-Galerkin theory, the system components such as resistor, inductor, capacitor, transmission lines, and switching devices are modeled in discrete wavelet domain for the purpose of steady-state analysis. To solve system equations, they are transferred to wavelet domain by forming algebraic matrix-vector relations using the wavelet transform coefficients and the equivalent circuit is thus built for system simulation. After describing the new algorithm, two-case studies are presented and compared with the simulations in the time domain to verify the accuracy and computational performance.

Power Systems Operation

Outages and planning primarily account for the removal and addition of new buses, generating power plants, transmission lines, loads, and control devices, respectively. They occur regularly in power systems operation and restoration, and hence a power system is constantly changing its topology. Therefore, there is a need for a software package to emulate these changes. Power System Analysis Toolbox (PSAT) is designed and developed in Matlab environment to simulate contingencies and expansion of power systems. The IEEE 14-bus power system is used to illustrate the effectiveness of the proposed work.

This article presents an efficient algorithm for computing a 10-point DFT. The proposed algorithm reduces the number of multiplications at the cost of a slight increase in the number of additions in comparison with the known algorithms. Using a 10-point DFT for harmonic power system analysis can improve accuracy and reduce errors caused by spectral leakage. This paper compares the computational complexity for an L×10M-point DFT with a 2M-point DFT.
