This paper proposes a mixed‐integer non‐linear programming (MINLP) model for the multi‐period active low voltage (LV) distribution network expansion planning problem, which can be solved by off‐the‐shelf optimization solvers. In addition, the wide‐spread penetration of solar resources, optimal loading of transformers, and modeling of the multiple solar generation patterns are considered in the model. The solar resources are of roof‐top household‐scale photovoltaic panel type, developed using a host‐owned business model and are able to exchange energy with the distribution company (DISCO). This model enables the DISCO, as the owner of the network, to minimize the investment and operation costs while being able to determine the optimal location and capacity of the distribution transformers, the service zone of distribution transformers, the optimal route of the distribution lines, and the total and annual planning costs. In order to check the efficiency of the proposed model, a 0.4 kV distribution test network is considered to plan the LV network of a residential district over a planning horizon of 5 years. Results show the effectiveness of the proposed model in dynamic expansion planning of the active LV distribution network. Also, results illustrates that the penetration of solar sources can be a great tool to improve the technical, economic, and environmental criteria for planning studies. Specifically while reducing the billing costs of customers, it favors the government to reduce the pollution costs, and it enables the DISCO to reduce the loss costs and maintain the voltage in the standard boundaries.

“…A multi-year ADN planning model including both traditional and smart grid technologies is presented in [5]. The authors in [6] propose a model for coordinated planning of MV and LV DNs considering DG penetration at the MV level. In [7], a riskmanaged planning model is developed using both network and nonnetwork solutions to find the least cost investment plan for utilities.…”

“…Index R in each parameter indicates the related region. (9) presents feeder cost:

F_{L V F_{M G (μ)}} = C o s t_{R}^{f} = A . C o s t_{1}^{f} + B . C o s t_{2}^{f} + C . C o s t_{3}^{f}

Moreover, the cost is obtained using Equation (10) below [36]. By using (10), the costs of LV feeders that are connecting DG to the cluster centre and cluster centre to the load point (including fixed and variable costs) are obtained.…”

Nowadays, the deployment of micro-grids (MGs) is one of the important trends in modern distribution network planning. Implementing this strategy aims to improve the ability of the distribution network to withstand extreme weather conditions and supplying critical loads. While the literature has focused chiefly on operating distribution systems and partitioning them into MGs, in this work, the idea of planning a new low voltage (LV) radial distribution system based on multi MGs for a greenfield is proposed. The main contribution is providing a framework to plan a resilient LV distribution system step by step for a new town without any operating grid. In the planning process, some MGs are formed and their service area and technical specifications like the number of MGs and their sizes are determined by a multi-objective optimization algorithm considering hardening and resiliency issues. The planning is done in a way that all predefined critical loads will be supplied. To consider the effects of extreme weather conditions, failure rates of poles and conductors due to thunderstorms are considered as a function of wind speed, and their appropriate models are used. The provided method is implemented in a test case with three major scenarios. Accordingly, planning in normal conditions considering hardening options and resilient network planning cases are evaluated. Simulation results and resiliency metrics are compared in detail.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
