“…The single‐level planning, which is frequently used in many studies, is most appropriate for a system with limited decision variables. However, in a multi‐contributor planning scheme with high decision variables, a multi‐level framework may be more effective and leads to a more precise result [22]. Here, however, the problem faces different situations including planning calculations, operational evaluation, and economic assessment.…”

In recent years, supporting schemes have been legislated by several governments to encourage private investors in installing renewable energy resources (RER). In such cases, the supportive policies are mainly enacted based on the either investor or distribution companies’ standpoint. In this paper, a distribution network expansion planning (DNEP) framework with the cooperation of residential private investors (RPI) is proposed. Due to the presence of a couple of main participants, the proposed framework is arranged in a bi‐level framework, where the RPI participation is optimized at the upper level, and the system structure is determined at the lower level. In order to assess the profitability of the project from the investors’ attitude, payback period years (PBY) is utilized. Meanwhile, due to the presence of uncertainty resources, fuzzy clustering method (FCM) is developed to catch the intermittency of the problem. The proposed framework is implemented on a real 81 bus distribution test system in Iran. Moreover, the existing scheme in Iran and also a modified plan are investigated to make cost‐effective decisions. Finally, sensitivity analysis is performed to reach a more beneficial result. Obtained results demonstrated how distribution companies can utilize the potential of residential customers in long‐term planning.

“…An optimal peak shaving strategy concerning dynamic FiT and demand was proposed in [31], where a day-ahead prediction was developed to determine the best values of elements. In our previous studies [32][33][34], the cooperation of private investors and distribution companies in long-term planning was considered. In these studies, a framework was introduced to conduct residential investors with respect to the distribution companies' targets.…”

“…The Iranian government, like many countries such as Brazil, India, Egypt, and Nigeria has enacted incentive policies in 2016 to persuade investors to contribute to projects [3]. Although these supporting policies incorporate various renewable resources like wind, photovoltaic (PV), hydropower, and thermal, PV systems have attracted remarkable attention in contrast to the other ones.…”

This paper investigates the impact of residential photovoltaic (PV) battery systems in a real test system with the goal of system peak load shaving. In order to encourage residential investors, a levelised feed‐in tariff (LFiT) scheme is introduced. Accordingly, two proposed cases and relevant suggestions are presented to reach a better performance. The profitability of the project is apprised via several economic criteria such as net present value, simple and discount payback period years (PBY and DPBY), internal rate of return (IRR), benefit to cost ratio, net cash flow, and levelised cost of energy. Moreover, different levels of peak shaving subject to customers’ participation and the size of the PV‐battery system are also obtained. An actual test system regarding 1‐year recorded data is employed to elevate the precision of results. Obtained results demonstrate that in the current situation in Iran, the PBY is about 5.83 years and the IRR is about 0.43. Meanwhile, the ratio of the LFiT should be about 3.5 to reach the same result as the current circumstances. Finally, a sensitivity analysis on systems’ parameters is performed to identify the impact of these parameters on economic indices.

“…For dual power supplies, the number of power supply access overload nodes should not exceed 50; the power of the second power supply is limited, and there is an expansion fee for expansion. Therefore, in the objective function, the related penalty coefficient problem of power expansion cost should be increased [10][11][12][13] .…”

A distribution network plays an extremely important role in the safe and efficient operation of a power grid. As the core part of a power grid’s operation, a distribution network will have a significant impact on the safety and reliability of residential electricity consumption. it is necessary to actively plan and modify the distribution network’s structure in the power grid, improve the quality of the distribution network, and optimize the planning of the distribution network, so that the network can be fully utilized to meet the needs of electricity consumption. In this paper, a distribution network grid planning algorithm based on the reliability of electricity consumption was completed using ant colony algorithm. For the distribution network structure planning of dual power sources, the parallel ant colony algorithm was used to prove that the premise of parallelism is the interactive process of ant colonies, and the dual power distribution network structure model is established based on the principle of the lowest cost. The artificial ants in the algorithm were compared with real ants in nature, and the basic steps and working principle of the ant colony optimization algorithm was studied with the help of the travelling salesman problem (TSP). Then, the limitations of the ant colony algorithm were analyzed, and an improvement strategy was proposed by using python for digital simulation. The results demonstrated the reliability of model-building and algorithm improvement.
