“…In [29], the authors presented an economic study that approved the economic benefits of using passive filters especially in the case of the nonlinear loads that exceed 1 MVA. In [30], the design of single tuned filters was carried out by using ETAP software in distribution systems with PV systems to eliminate the harmonics and their impact on the system. A comprehensive analysis of the single tuned filter parameters selection and its effect on the harmonic mitigation is presented in [16].…”

In recent years, with the widespread use of non-linear loads power electronic devices associated with the penetration of various renewable energy sources, the distribution system is highly affected by harmonic distortion caused by these sources. Moreover, the inverter-based distributed generation units (DGs) (e.g., photovoltaic (PV) and wind turbine) that are integrated into the distribution systems, are considered as significant harmonic sources of severe harmful effects on the system power quality. To solve these issues, this paper proposes a harmonic mitigation method for improving the power quality problems in distribution systems. Specifically, the proposed optimal planning of the single tuned harmonic filters (STFs) in the presence of inverter-based DGs is developed by the recent Water Cycle Algorithm (WCA). The objectives of this planning problem aim to minimize the total harmonic distortion (THD), power loss, filter investment cost, and improvement of voltage profile considering different constraints to meet the IEEE 519 standard. Further, the impact of the inverter-based DGs on the system harmonics is studied. Two cases are considered to find the effect of the DGs harmonic spectrum on the system distortion and filter planning. The proposed method is tested on the IEEE 69-bus distribution system. The effectiveness of the proposed planning model is demonstrated where significant reductions in the harmonic distortion are accomplished.

“…Penetration of RESs in the distribution system can achieve many economical, technical and environmental benefits. In [1–4], RES‐based DGs were integrated to reduce the power losses in the distribution systems as a technical benefit. In [5], PV and wind sources are used for achieving environmental, technical and economic benefits by reducing the distribution system emissions, power losses and energy production costs.…”

“…Biogas power plants have synchronous generator which usually does not affect power quality, especially in terms of THD. Effects of PV system on power quality are described in [4][5][6][7][8]. In [4], authors investigated how power output variations caused by cloud shadows affect voltage and current at the point of common coupling and consequently, power quality of the system and fluctuations of a PV system due to a cloud shadow are simulated.…”

“…El-Sayed et al in [5] analysed harmonics determined by a photovoltaic (PV) system on a distribution system with a goal to solve the harmonic reduction problem of distribution system which is fed from the PV system by using a number of single-tuned passive filters. The results in [5] showed that the best location for PV is far away from the utility the while the best location for the filter is near the utility. Simplified model which presents dynamics of the distribution network with PV systems for the power quality studies is presented in [9].…”

Here, the impacts of biogas power plants and photovoltaic (PV) power plants on the power quality in the distribution network are presented and analysed. The biogas power plant's influence on the current harmonics is explored, as a synchronous generator powers the biogas power plant, and the PV plants are connected to the distribution network via the inverter. All the analyses are based on actual measurements that are performed in the last 10 years. Results of the analysis of these numerous measurements were a challenge for investigation how large share of PV systems in distribution network with non-linear loads influence on THD from one side and how biogas power plant with a synchronous generator can improve THD from the other side. In order to investigate interaction of the biomass power plant and PV power plants on the power quality in distribution network, computer model was developed in DIgSILENT Power Factory where PV power plant and household were modelled as a source of current harmonic injections and biomass power plant was modelled as synchronous machine, as a source of voltage harmonics. Analysis of harmonic behaviour in different scenarios is examined through the performed simulations.
