“…Because the nominal current influences the compensator price, so in many works it has just been assumed that the optimization of compensator sizes leads also to the cost reduction and the economic goal is automatically taken into account [14,16,20,21]. This paper shows that such simplified approach could lead to suboptimal solutions.…”

“…Significantly better results can be obtained when parallel or series active power filters (APF) [1], hybrid filters or UPFC (Unified Power Flow Controller) systems [2] are applied to limit higher harmonics. The optimal sizing and allocation of compensators have been considered for passive [3][4][5][6] and active or hybrid filters [7][8][9][10][11][12][13][14][15]. This paper presents a solution of the problem for active power filters.…”

“…The other approach consists in minimization of the telephone interference factor (TIF), voltage total harmonic distortion (THD), harmonic transmission line losses or motor load losses, while keeping the compensator currents below the specified values [7-10, 17, 18]. Sometimes a multi-objective optimization approach is used in order to simultaneously minimize a few objective functions [6,14,19,20].…”

Abstract. The significant problem of compensator placement and sizing in electrical networks has been analyzed in the paper. The compensation is usually realized by means of passive or active power filters. The former solution is widely used mainly because of the economical reasons, but the latter one becomes more and more popular as the number of nonlinear loads increases. Regardless of the compensator type the most important goal consists in voltage and current distortion drop below levels imposed by standards. Nevertheless, the desired effects should be achieved with the minimum cost. So far a few objective functions have been proposed for this optimization problem. It is claimed that minimization of the compensator currents leads also to the minimum costs. This paper shows that such simplified approach could lead to suboptimal solutions and in fact a function g(·) reflecting the relation between the compensator size and its price must be incorporated into objective functions. Moreover, in this case it is very easy to compare solutions obtained using compensators offered by different suppliers -it is enough to change the function g(·). Theoretical considerations have been illustrated by an example of active power filter allocation and sizing.

“…The capacity is currently designed based on the configuration of the charger and the total harmonic distortion of the current, and then corrected by a safety factor [22]. However, the existing method cannot determine the safety factor accurately because the interaction between the harmonic current and harmonic voltage of the charging station is not considered, and an accurate method of selecting the safety factor has not been proposed.…”

Abstract:The influence of electric vehicle charging stations on power grid harmonics is becoming increasingly significant as their presence continues to grow. This paper studies the operational principles of the charging current in the continuous and discontinuous modes for a three-phase uncontrolled rectification charger with a passive power factor correction link, which is affected by the charging power. A parameter estimation method is proposed for the equivalent circuit of the charger by using the measured characteristic AC (Alternating Current) voltage and current data combined with the charging circuit constraints in the conduction process, and this method is verified using an experimental platform. The sensitivity of the current harmonics to the changes in the parameters is analyzed. An analytical harmonic model of the charging station is created by separating the chargers into groups by type. Then, the harmonic current amplification caused by the shunt active power filter is researched, and the analytical formula for the overload factor is derived to further correct the capacity of the shunt active power filter. Finally, this method is validated through a field test of a charging station.

“…Among the AI techniques, evolutionary computing methods such as genetic algorithm (GA) [12], particle swarm optimization (PSO) [13], bacterial foraging technique [14], ant colony optimization [15] and tabu search [16] have been reported to produce superior results. However, one common drawback of these techniques lies in the huge computing task involved in obtaining the solution.…”

Active power filters (APF) can be employed for harmonic compensation in power systems. In this paper, a fuzzy based method is proposed for identification of probable APF nodes of a radial distribution system. The modified adaptive particle swarm optimization (MAPSO) technique is used for final selection of the APFs size. A combination of Fuzzy-MAPSO method is implemented to determine the optimal allocation and size of APFs. New fuzzy membership functions are formulated where the harmonic current membership is an exponential function of the nodal injecting harmonic current. Harmonic voltage membership has been formulated as a function of the node harmonic voltage. The product operator shows better performance than the AND operator because all harmonics are considered in computing membership function. For evaluating the proposed method, it has been applied to the 5-bus and 18-bus test systems, respectively, which the results appear satisfactorily. The proposed membership functions are new at the APF placement problem so that weighting factors can be changed proportional to objective function.
