“…For this reason, the scientific literature presents just a few works in this research field, that only border on the main research problem of finding the optimal planning solution properly taking into account cyber-risks (see Section 2). Wang et al in [51] propose an optimisation model for distributed generation and grid expansion planning taking into account substations failures due to cyber failures. The authors model the cyber failures events with random parameters characterized by a constant failure rate, and aim at minimizing the investments taking into account the costs of energy not supplied due to cyber failures.…”

During the grid planning process, electric power grid companies evaluate different options for the long-term grid development to address the expected future demands. The options can be passive measures, e.g., traditional reinforcement or building new lines, or active measures, e.g., support from ICT-solutions during operation to increase the power transfer capability. The ongoing digitalization of the electric power grid inevitably push the grid companies to assess potential cyber risks as part of the grid planning process. This applies especially for active measures which to a greater extent rely on support from ICT-solutions to operate the system closer to its limits. However, current grid planning approaches do not adequately provide the support needed in practice, and the industry is struggling to adopt and execute cyber-risk assessments. The contribution of this paper is threefold. First, we interview six companies from the energy sector, and based on the interviews we identify seven success criteria that cyber-risk assessment methods for the electric power sector need to fulfil to provide adequate support. Second, we present four risk assessment methods and evaluate the extent to which they fulfil the identified success criteria. Third, we address the specific need for approaches that are easy to use and comprehend, especially for grid planning purposes, and propose a low-threshold approach to support high-level cyber-risk assessment in an electric power grid planning process. Based on our findings, we provide lessons learned in terms of gaps that need to be addressed to improve cyber-risk assessment in the context of smart grids.

“…Moreover, in reference [28], similar to reference [33], simultaneous sub-transmission and distribution planning is performed, taking into account losses and reliability, with a specific emphasis on reliability. References [34] and [35] also aim to perform simultaneous network planning for electrical and thermal distribution systems. To simplify the planning in this case, only the costs of construction and operation are considered in their objective functions.…”

Development planning of electrical distribution networks is one of the oldest issues that has been addressed in the field of distribution system engineering, and numerous studies have been conducted in this regard. However, it should be noted that ultimately, it is the distribution companies that implement the development plans, and network planning should be carried out from an economic perspective for these companies, with an operational approach. In this research, a new approach is proposed for network planning issues, aiming to demonstrate the role of regulators as mediators of the common interests of electricity network consumers. The goal is to find a planning solution that not only focuses on the economic aspects and cost reduction for the distribution company but also ensures the common interests of consumers and governance, particularly in terms of reliability to a desirable extent. The proposed approach utilizes a genetic algorithm to solve a location-allocation problem and determine the capacity of distribution substations. It has been implemented and demonstrated the efficiency of the approach by discussing the objective functions, the performance of the distribution company, and its effectiveness.

“…The DSP optimization problem was solved using conventional mathematical techniques [2,[7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] as well as heuristic techniques [22][23][24][25][26][27]. Though heuristic techniques give reasonable results in rapid computation time, still the mathematical techniques provide better optimal solutions.…”

<span>This paper presents three planning models for optimal routing of radial distribution systems. In the first two models, the cost function includes capital cost of lines, energy loss cost, and bays cost. The constraints equations include power balance equations, voltage drop equations, radiality equations, logic equations, thermal limit equations, and bus voltage limit equations. The first model considers the energy loss equation in its quadratic form while the second model approximates the energy loss equation of each cable size by a simple linear segment considering the economic loading of each cable size. In the third model, two sub-models are used where the first one gets the optimal radial network configuration regardless of the cable sizes and voltage constraints. In the second sub-model the best cable size on each selected line of the first model is determined to minimize the system costs while considering the bus voltage limit constraint and thermal limit constraint. Verification of the proposed planning models has been made using a real 11 kV 34-bus distribution network with 68 initial lines.</span>
