In the article, the distribution of symmetrical loads operating in extreme load, taking into account the total power of the consumers in the power network, was modeled by installing solar panels in apartments. As a result, as a result of the use of solar panels with a total power of 34 kW in the houses in the cable distribution network with a length of 0.444 km, a reduction of active power loss of 21382 kWh (37%) is achieved, a reduction of reactive power loss is achieved by 7309kVAR*hour (37%), the level of overloading of the cable network was 1- in the section of households, from 105% to 85%, and in the section of the last households, a decrease is achieved from 14% to 6%. In addition, it was found that the voltage drop at the ends of the apartments is not at the required level, and when the solar panels are connected, it is at the limit values.

“…При этом существует проблема качества электроэнергии, которое контролируется посредством измерения показателей качества электроэнергии (ПКЭ) в точках присоединения потребителей [1]. Среди основных причин отклонения ПКЭ при централизованном электроснабжении от допустимых значений можно выделить несимметричность нагрузки, нелинейность электроприемников и протяженность системы [2,3]. Для поддержания ПКЭ в пределах допустимых значений применяют корректирующие устройства, например симметрирующие устройства, батареи конденсаторов, вольтодобавочные трансформаторы [4,5].…”

“…To meet the need of society and people concerning electricity, researchers are currently developing innovative methods to improve the network [1]. Moreover, the LVAC distribution networks are almost radial unbalanced networks due to the presence of 1-phase loads [2,3] in networks. Various authors have studied the planning of LV distribution systems for electrification.…”

The low voltage (LV) distribution systems are extended year by year due to the increase in energy demand. To overcome this issue, distribution system utilities have been focusing on designing and operating an appropriate distribution system with minimum capital and operational expenditure for supplying electricity to users. This article compares different algorithms to design an LVAC distribution system in a rural area, which focuses on minimizing the total length of lines and the power losses and balancing the loads among the three phases including the economic evaluation of the grid-connected PV system. Firstly, the shortest path (SP) algorithm is established to search for the minimization of the conductor used. Secondly, three different algorithms which are repeated phase sequence (RPABC), first fit bin packing (FFBP), and mixed-integer quadratic programming (MIQP) algorithms are developed to balance the load and minimize power losses. Next, a comparative result of three different algorithms is provided. Finally, the techno-economic analysis of the grid-connected PV system with different electricity tariffs with hybrid optimization of multiple energy resources (HOMER) software is studied in the planning period. To validate a proposed method, the 129-buses low voltage distribution in a rural village, in Cambodia, is tested. The simulation result confirms the optimal solution of the MIQP algorithm and PV system integration in designing a distribution system in a particular case study.
