“…It can be used to quantify the harmonic distortion for power systems and to determine whether dangerous resonant problems exist. Commonly-used harmonic analysis methods can be divided into two categories [1][2][3][4][5][6][7][8][9][10][11][12]. The first category is based on the techniques of time-domain analysis, wavelet analysis, etc.…”

“…Many methods have been proposed to analyze and eliminate the harmonic impact produced by nonlinear loads [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Among them, harmonic analysis is one of the most powerful tools for harmonic impact analysis.…”

“…Time-domain-based methods are very flexible, but it is difficult to consider nonlinear loads in terms of specified power and they often lead to long simulation times. The second category is based on the techniques of steady-state analysis, which has better computational performance and therefore is suitable for large-scale power system analysis [1][2][3][4][6][7][8][9][10][11][12]. Steady-state-based methods are mostly developed based on load flow programs or admittance matrix inverses and employ frequency-based component models.…”

Due to the unbalanced features of distribution systems, a three-phase harmonic analysis method is essential to accurately analyze the harmonic impact on distribution systems. Moreover, harmonic analysis is the basic tool for harmonic filter design and harmonic resonance mitigation; therefore, the computational performance should also be efficient. An accurate and efficient three-phase harmonic analysis method for unbalanced distribution systems is proposed in this paper. The variations of bus voltages, bus current injections and branch currents affected by harmonic current injections can be analyzed by two relationship matrices developed from the topological characteristics of distribution systems. Some useful formulas are then derived to solve the three-phase harmonic propagation problem. After the harmonic propagation for each harmonic order is calculated, the total harmonic distortion (THD) for bus voltages can be calculated accordingly. The proposed method has better computational performance, since the time-consuming full admittance matrix inverse employed by the commonly-used harmonic analysis methods is not necessary in the solution procedure. In addition, the proposed method can provide novel viewpoints in calculating the branch currents and bus voltages under harmonic pollution which are vital for harmonic filter design. Test results demonstrate the effectiveness and efficiency of the proposed method.

“…Many methods have been devised for an optimal PHF planning in the literature. Conventional methods of search and optimization are slow in finding a solution in a very complex search space [3,4]. Hence, some methods such as artificial neural networks (ANNs) [5] or genetic algorithms (GAs) [6,7] are widely applied for searching an optimal solution of locating and sizing passive filters.…”

The harmonic in distribution systems becomes an important problem due to an increase in nonlinear loads. This paper presents a new approach based on a graph algorithm for optimum placement of passive harmonic filters in a multi-bus system, which suffers from harmonic current sources. The objective of this paper is to minimize the network loss, the cost of the filter and the total harmonic distortion of voltage, and also enhances voltage profile at each bus effectively. Four types of sub-graph have been used for search space of optimization. The method handles standard capacitor sizes in planning filters and associated costs. In this paper, objective function is not differential but eases solving process. The IEEE 30 bus test system is used for the placement of passive filter. The simulation has been done to show applicability of the proposed method. Simulation results prove that the method is effective and suitable for the passive filter planning in a power system.
