“…It has advantages of comparatively higher reliability, DG penetration, better voltage response (for DG critical voltage mode) and comparatively fewer power losses compared to LDN from objective viewpoint [74,75]. However, complex fault traceability makes is more susceptible to faults and early recovery from reliability viewpoint in traditional planning methods [76]. The limitations in MDN, serve as a vital research area, from planning and operation perspective.…”

Smart grids (SGs), as an emerging grid modernization concept, is spreading across diverse research areas for revolutionizing power systems. SGs realize new key concepts with intelligent technologies, maximizing achieved objectives and addressing critical issues that are limited in conventional grids. The SG modernization is more noticeable at the distribution grid level. Thus, the transformation of the traditional distribution network (DN) into an intelligent one, is a vital dimension of SG research. Since future DNs are expected to be interconnected in nature and operation, hence traditional planning methods and tools may no longer be applicable. In this paper, the smart distribution network (SDN) concept under the SG paradigm, has presented and reviewed from the planning perspective. Also, developments in the SDN planning process have been surveyed on the basis of SG package (SGP). The package presents a SDN planning foundation via major SG-enabling technologies (SGTF), anticipated functionalities (SGAF), new consumption models (MDC) as potential SDN candidates, associated policies and pilot projects and multi-objective planning (MOP) as a real-world optimization problem. In addition, the need for an aggregated SDN planning model has also been highlighted. The paper discusses recent notable related works, implementation activities, various issues/challenges and potential future research directions; all aiming at SDN planning.

The capability of the classical network to support the level penetration of Distribution Generation (DG) has been present to analysis how to achieve a better integration of flexible demand of Electrical Networks(Mesh and Radial systems). Based on this analysis, two simulation algorithms have been proposed to reduce CPU time and memory, can help the grid operator to assess power situation and increase penetration level of DG.Firstly, It deals with an algorithm developed for power load flow studies in electrical power systems using Schur complement method. By dividing Jacobian matrix into two separated matrices with reasonable computation time, It could be avoided divergence of the solution. A next step that was applied concerned Data Compression for the Simulated algorithms conceived to study load flow calculation in electrical power systems. Real time monitor of grids required less computation time in calculation of power system analysis. It proposed an algorithm based on Run Length Encoding (RLE) method where no zero values are included. Matlab results obtained by applying these algorithms match the analytical approaches. Results have been compared with Newton Raphson and Fast Decoupled methods in term of influence of convergence properties and it's efficiency. These methods have been implemented and tested on several IEEE bus test systems.

“…In areas where the expected service quality is high, the secured feeder can evolve into two main structures: the grid and the loop [14], which are also radially operated. The redundant paths increase the service quality but the operation of such structures can be very complex, and can also be very expensive.…”

Distribution networks will experience a deep mutation concerning their planning and operation rules due to the expected increase of distributed generation (DG) interconnection to the grid. Indeed, the opening of the electricity market or the growing global concern for environmental issues will lead to a massive development of DGs. Yet, a too large amount of DGs could raise technical problems on distribution networks which have not been planned to operate with bi-directional power flow. The existing solutions to solve marginal DG connections could be no longer relevant. The distribution network definitely has to evolve towards a smarter and more flexible network. Two possible ways to reach this goal are through new architectures and developing intelligent systems. This paper focuses on new architectures and operating modes. The traditional radial distribution network could accept more DGs by introducing appropriately specific loops. A new hybrid structure enabling the coexistence of the radial and meshed operation is proposed. It is equipped with autonomous circuit-breakers and automated switches that improve its reliability. A heuristic algorithm is also proposed to build this new architecture while ensuring the equality of consumers with respect to the continuity of service and while minimizing the global cost.
